* Avoid calling close(-1)Gravatar wm42017-06-29
| | | | | | | | | | While this is perfectly OK on Unix, it causes annoying valgrind warnings, and might be otherwise confusing to others. On Windows, the runtime can actually abort the process if this is called. push.c part taken from a patch by Pedro Pombeiro.
* stream_bluray: change license to LGPLGravatar wm42017-06-26
| | | | | | | | While I'm not particularly attached to this, the history is pretty simple, and all relevant authors have agreed. 2f004875: removed in 2c693a47, patch author was not asked. 1ef239a4: removed, author was not asked.
* demux_mf, stream_mf: change license to LGPLGravatar wm42017-06-24
| | | | | | | | | | | | | | | | | | | cehoyos, who did not agree to the relicensing, added bcb5c78ce3. If there was copyright, we consider it gone, because the table changed. It does not map file extension to a FourCC anymore, and codecs.conf is gone. The new mapping is a libavcodec codec name (happens to be the same as the file extension). The same applies to commits 60ecafec, b749836b, 5b3e3be1. None of these authors were contacted. These were before the code was replaced with a table (in d0326807). The parts outside of demux_mf.c were removed a long time ago. Like in the previous comment, we don't think any copyright applies at least to the new code (at least after the FourCC removal). iive authored 0aa37a0d, which is probably still left in some form, and makes demux_mf.c "LGPL 3 or later". stream_avdevice.c (unrelated) has been marked as LGPL before.
* stream: move cache option declarations to cache.cGravatar wm42017-06-23
| | | | | | | | If they are copyrightable, iive's changes (commits listed in cache.c) would make them LGPL 3+. To avoid that options.c becoming LGPL 3, move the option declarations to cache.c. struct mp_cache_opts is still in options.h, but we consider that irrelevant, and options.h will become LGPL 2.1+ later.
* build: simplify OSS checks and remove changes by "bugmen0t"Gravatar wm42017-06-22
| | | | | | | | | | | | | | | | | | The user bugmen0t was apparently a shared github account with publicly available login. Thus, we can't get LGPL relicensing permission from the people who used this account. To relicense successfully, we have to remove all their changes. This commit should remove 20d1fc13, f26fb009, defbe48d. It also should remove whatever test fragments were copied from the ancient configure, as well as some configure logic (potentially that device path stuff). I think this change still preserves the most important use-cases of OSS: BSDs, and the Linux OSS emulation (the latter for testing only). According to an OSS user, the 4front checks were probably broken anyway. The SunAudio stuff was probably for (Open)Solaris, which is dead. ao_oss.c itself will remain GPL, and still contains bugmen0t changes.
* stream: change license to LGPLGravatar wm42017-06-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All relevant authors have agreed. There are two exceptions, patches by authors who could not be reached. This commit tries to remove their copyright. a0f08fbe: messes with the seeking code corner cases. The EOF flag logic was changed at some point, and always had a flaky history (see e.g. 347cf972 50274ca3 70411f27 5999efb9 0d5e6084 ff08d0c3 2e2f77e3 de5566f0 9554a844, all which happened after that patch, MPlayer ones without that patch). I claim that all of the copyright the patch might have added is gone. Except the message in stream_seek(), which this commit removes. The other code removed/changed in stream_seek() is probably not from that patch, but it doesn't hurt to be sure, and also makes it more readable. (It might change the behavior so that sometimes the eof flag is set after a seek, but it doesn't matter here.) 2aa6acd9: it looks like the seek_forward() modified by this patch was later moved to stream.c and renamed to stream_skip_read() in a790f2133. (Looking closer at it, it was actually modified again a bunch of times, fixing the logic.) I rewrote it in this commit. The code ended up rather similar, which probably could lead to doubts whether this was done properly, but I guess the reader of this will just have to believe me. I knew what stream_skip_read() was supposed to do (which was reinforced when I tried to replace it on the caller side), without reading the pre-existing code in detail. I had to "relearn" the logic how buf_pos and bug_len work - it was actually easy to see from stream_read_char() how to skip the data, essentially by generalizing its logic from 1 byte to N bytes. From the old code I only "used" the fact that it's obviously a while(len>0) look, that has to call stream_fill_buffer repeatedly to make progress. At first I actually didn't use stream_fill_buffer_by(), but the variant without _by, but readded it when I checked why the old code used it (see cd7ec016e7). This has to be good enough. In the end, it's hard to argue that this could be implemented in a way not using such a loop. Other than this, I could add the usual remarks about how this code was not modularized in the past, and how stream.c contained DVD code, and how this was later modularized, moving the copyright to other files, and so on. Also, if someone wrote a stream module, and was not asked about LGPL relicensing, we don't consider the entry in stream_list[] copyrightable.
* Drop/move img_fourcc.hGravatar wm42017-06-18
| | | | | | | | | | | | | | | This file is an leftover from when img_format.h was changed from using the ancient FourCCs (based on Microsoft multimedia conventions) for pixel formats to a simple enum. The remaining cases still inherently used FourCCs for whatever reasons. Instead of worrying about residual copyrights in this file, just move it into code we don't want to relicense (the ancient Linux TV code). We have to fix some other code depending on it. For the most part, we just replace the MP_FOURCC macro with libavutil's MKTAG (although the macro definition is exactly the same). In demux_raw, we drop some pre-defined FourCCs, but it's not like it matters. (Instead of --demuxer-rawvideo-format use --demuxer-rawvideo-mp-format.)
* stream_file: option to close fd after use -> fdclose://Gravatar sfan52017-06-16
| | | | | fdclose://123 will instruct mpv to close the file descriptor when it is no longer needed (usually when playing finishes).
* stream_lavf: change license to LGPLGravatar wm42017-06-16
| | | | | | | | | | All authors agreed. The author of 1ee8ce75 did not respond, but it was a mpv pull request, and at this time DOCS/contribute.md and the "Copyright" file stated that all contributions must include LGPL relicensing permission. But you could claim that this was too "hidden". Sort of a corner case, I guess, but not my problem.
* stream: rewrite url escaping/unescaping functionsGravatar wm42017-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | The original functions come from 24c6f11c8b8, which says that these functions were copied from another project. This other project is GPL and was written by an unknown author, so there is no hope to relicense them to LGPL. Replace the existing functions with code written by Avi Halachmi. He did not see the old code, but wrote it based on the function signature and an extended description of what they should do (http://sprunge.us/edia). Some additional help was provided by me (in particular the function of the "ok" parameter and how to implement it - not in the original ASFRecorder code). Some of the code is hilariously similar, but these are coincidences. The name of the variable "c" probably "leaked" from me, but "o" is a true coincidence. The code was integrated by me - my only change is changing the function names to the old ones, moving the order of the top-level declarations, and changing "default_ok" to "url_default_ok", and changing the strings from char* to char[]. The author of the new code is Avi Halachmi.
* cache: move duplicated condition to a functionGravatar wm42017-05-15
| | | | | While subtly duplicating such checks happens a lot in this file, this particular case can be easily factored into a function.
* cache: fix unnecessary seek blocking from f4d62dc4a0Gravatar Uoti Urpala2017-05-15
| | | | | | | | | | | | | | | | | | | | | Commit 374600cec0 ("cache: propagate seek failures") changed stream-level seeks to be done in the calling thread so possible errors could be reported. This commit included some rationale why doing the stream-level seeks synchronously was not a big issue. However, the following fixup commit f4d62dc4a0 changed the seek code to always synchronize with the cache thread and do seek handling there. This is a problem because it affects even seeks within already cached data (which require no stream-level seek). With a network server that sends data in bursts, the cache thread can be blocked in a read call for a long time; the added synchronization means that seeking within already downloaded data can have unnecessary long delays. Change cache_seek() to check whether the seek is expected to result in a stream-level seek, and skip synchronization if it is not. This means that seeks within the cached portion of the file now again happen immediately without possibly waiting for network. Signed-off-by: wm4 <wm4@nowhere>
* cache: clarify that copyright will be changed to LGPL v2.1 if possibleGravatar wm42017-05-11
| | | | | | Clearly the licensing situation isn't confusing enough. I don't know why that guy insists on LGPLv3.
* stream_smb: disable by default, mark as GPLv3Gravatar wm42017-05-11
| | | | | | | | | | It seems libsmbclient has been GPLv3 for years. Also, it's certainly not LGPL (unlike some of its support libs like talloc). Thus, mpv built with Samba support is GPLv3. Disable it by default, so we don't have to go through the trouble to indicate the correct license in our output, and we don't trick people into distributing stuff under the wrong license.
* stream_file: change license to LGPLGravatar wm42017-05-11
| | | | | | | | | | | | | | | | | | | | | This has a messy history all back to the initial commit with multiple refactors, but it seems almost all authors agreed. Exceptions: 2aa6acd9747: patch by someone who could not be reached. Whether or not this code is still in mpv is unknown, but the affected code was moved to stream.c at one point anyway. 3859bbd9fef: not sure if this is a patch by the mentioned person (I assume not) or the committer (who agreed to LGPL), but it seems the change is too trivial to affect copyright. It seems even the FD check can be dropped, which I'm doing in this commit. 58846451f0e: author doesn't reply. But reverting this and letting someone who has never seen this commit before redo it would lead to exactly the same code. So I'm claiming that the change is not copyrightable.
* cookies: change license to LGPLGravatar wm42017-05-11
| | | | | | | All authors have agreed. One minor exception is 21a9221e7bb2 (patch by someone who wasn't asked), but we just remove the added line again. It seems unneeded.
* cache: change license to LGPL v3Gravatar wm42017-05-08
| | | | | | | | | | | | | All authors have agreed to the relicensing. iive has insisted on "LGPL v3 or later", which makes the file LGPL v3. His commits are the following: 84ec57750883 9b0d8c680f63. All other contributions are LGPL v2.1. I hope we can remove these changes completely one day to make this file LGPL v2.1. iive also authored commit 3934b160a829, but this code is completely gone today. (fork() and shared memory use was removed completely in favor of threads.)

* wscript: decouple dvdnav check from dvdreadGravatar Ricardo Constantino2017-03-31
| | | | | | | | | Reallows enabling dvdnav without enabling dvdread which was broken in 77cbb3543 when they were both disabled by default. Since dvdnav requires dvdread, we can enable dvdread:// even if --enable-dvdread isn't passed. Fixes #4290
* stream/stream_dvdnav: show list of titles on verboseGravatar Ricardo Constantino2017-03-29
| | | | Same as stream_bluray, but only if no title is selected already.
* stream/stream_dvdnav: don't ignore setting titleGravatar Ricardo Constantino2017-03-29
| | | | | Probably a typo in 5e30e7a04. Fixes #4283
* stream_dvd: fix subs/audio detection on DVDs containing multi-PGC titlesGravatar qrwyeui2017-03-15
| | | | | | | | | | On some DVDs, title number is not necessarily the same as the (first) PGC number. (Most often they are equal, since there's usually exactly one PGC per title, which is likely why this issue wasn't noticed before.) When searching for audio/subtitle metadata, we want to look at the actual PGC we're about to play. See discussion in issue #4235. Signed-off-by: wm4 <wm4@nowhere>
* dvb: add support for DVB-T2Gravatar ivan-832017-03-06
| | | | | | | | | | | | | | | | | | | | | | | | Probably does much more: + add support DVB-T2 * DVB params set to AUTO by default * MAX_CARDS: 4 -> 16 * DMX_SET_BUFFER_SIZE: 64kb -> 256kb + add DTV_CLEAR call before tune + add logic from https://github.com/olifre/mpv/commits/dvb-mixed-api-scan * rename type to delsys * single playlist per adapter * card -> adapter * fix channels order in playlist * update internal api * auto fallback to old DVB API on tune * fix DELSYS_SUPP_MASK value * remove tone - unused * add channel mem zeroize in config parser + add code from libdvbv5 for detect delivery systems * SYS_DVBC_ANNEX_AC replaced to SYS_DVBC_ANNEX_A + SYS_DVBC_ANNEX_C Signed-off-by: wm4 <wm4@nowhere>
* Revert "dvb: add support for DVB-T2"Gravatar wm42017-02-14
| | | | | | | | This reverts commit df91e492fd3365cf7db9c6ba4a721f8fcce0521c. Multiple issues such as weird code with undefined behavior (like (like conf_file*). The PR wasn't properly reviewed anyway (my error), so this commit should be reviewed and then merged again.
* dvb: add support for DVB-T2Gravatar ivan-832017-02-13
| | | | | | | | | | | | | | | | | | | | | | | | Probably does much more: + add support DVB-T2 * DVB params set to AUTO by default * MAX_CARDS: 4 -> 16 * DMX_SET_BUFFER_SIZE: 64kb -> 256kb + add DTV_CLEAR call before tune + add logic from https://github.com/olifre/mpv/commits/dvb-mixed-api-scan * rename type to delsys * single playlist per adapter * card -> adapter * fix channels order in playlist * update internal api * auto fallback to old DVB API on tune * fix DELSYS_SUPP_MASK value * remove tone - unused * add channel mem zeroize in config parser + add code from libdvbv5 for detect delivery systems * SYS_DVBC_ANNEX_AC replaced to SYS_DVBC_ANNEX_A + SYS_DVBC_ANNEX_C Signed-off-by: wm4 <wm4@nowhere>
* dvb: move priv allocation to dvb_openGravatar Thomas V2017-02-10
| | | | | | | This fixes a crash when changing channels; previously stream->priv would not be initialized when dvb_get_state reused the existing state. Signed-off-by: Thomas VanSelus <tvanselus@diospyros.us>
* tv: Zero-out newly-allocated handle in tv_new_handle()Gravatar Frédéric Brière2017-02-05
| | | | | | | Some fields (notably tv_channel_list) were left uninitialized, potentially causing problems later on. Fixes #4096
* stream: get rid of streamtype enumGravatar wm42017-02-02
| | | | | | | | | Because it's kind of dumb. (But not sure if it was worth the trouble.) For stream_file.c, we add new explicit fields. The rest are rather special uses and can be killed by comparing the stream impl. name. The changes to DVD/BD/CD/TV are entirely untested.
* stream: better method signal caching, rename weird uncached_stream fieldGravatar wm42017-02-02
| | | | | | | | "uncached_stream" is a pretty bad name. It could be mistaken for a boolean, and then its meaning would be inverted. Rename it. Also add a "caching" field, which signals that the stream is a cache or reads from a cache. This is easier to understand and more flexible.
* tvi_dummy: don't return bad dummy PTSGravatar wm42017-02-02
| | | | This makes the player spam timestamp warnings. Return NOPTS instead.
* stream: minor cleanup to previous commitGravatar wm42017-01-27
| | | | | | | This is almost cosmetic, but removes the duplicated EOF-setting. Somewhat oddly, this will enter the reconnect path and exit it immediately again - should be fine.
* stream: set EOF if stream is canceledGravatar wm42017-01-26
| | | | | | | | | Commit 7be495b3 added the cancellation test, but forgot to set the eof flag. This could lead to demux_mkv.c not terminating if the stream was cancelled in some code paths. This function is what is supposed to set the EOF flag in the first place, so just add the missing code.
* stream_lavf: add support for data URIsGravatar Ricardo Constantino2017-01-25
| | | | | | | Only FFmpeg supports them and they need to be in the format data:// like other protocols or prefixed with ffmpeg:// or lavf://. Closes #4058
* stream: check for playback aborts on reading tooGravatar wm42017-01-24
| | | | | | | | | Benefits demux_mkv.c, or demux_lavf.c during probing. In particular demux_lavf.c can sometimes get "stuck" when reading from a slow/blocking source, and if probing needs more than a few iterations. Since this is a read of an atomic variable with relaxed semantics, this should have no impact on reading speed at all, not even theoretically.
* player: remove --stream-capture option/propertyGravatar wm42017-01-21
| | | | | | | | | | | | | | | This was excessively useless, and I want my time back that was needed to explain users why they don't want to use it. It captured the byte stream only, and even for types of streams it was designed for (like transport streams), it was rather questionable. As part of the removal, un-inline demux_run_on_thread() (which has only 1 call-site now), and sort of reimplement --stream-dump to write the data directly instead of using the removed capture code. (--stream-dump is also very useless, and I struggled coming up with an explanation for it in the manpage.)
* stream_bluray: use proper 0-based idxGravatar Ricardo Constantino2017-01-16
| | | | | | | | | | | | | | | | | | | | | | | | | Even though the title list code was copied from FFmpeg/libbluray, I didn't check that mpv used 0-based title indexing. $ mpv bd://1 --bluray-device=. --msg-level=bd=v [bd] Opening bd:// [bd] List of available titles: [bd] idx: 1 duration: 00:00:36 (playlist: 00000.mpls) [bd] idx: 2 duration: 01:31:30 (playlist: 00001.mpls) [bd] idx: 3 duration: 00:00:50 (playlist: 00003.mpls) bd://1 actually opens idx 2 from the list, not 1. bd://mpls/1 opens playlist 00001.mpls as expected. With this commit: $ mpv bd://1 --bluray-device=. --msg-level=bd=v [bd] Opening bd:// [bd] List of available titles: [bd] idx: 0 duration: 00:00:36 (playlist: 00000.mpls) [bd] idx: 1 duration: 01:31:30 (playlist: 00001.mpls) [bd] idx: 2 duration: 00:00:50 (playlist: 00003.mpls) should play the expected idx 1.
* cache: remove redundant free()Gravatar wm42017-01-09
| | | | | | This code used to check/free multiple things, so the argument to free() was not always NULL. After the code was simplified, the free() became redundant.
* demux, stream: add option to prevent opening referenced filesGravatar wm42016-12-04
| | | | Quite irresponsibly hacked together. Sue me.
* tv: fix option typeGravatar wm42016-11-22
| | | | | It appears this makes it actually compatible with the property. It was an ancient MPlayer artifact all along.
* stream_bluray: check title index/playlist rangeGravatar schnusch2016-10-17
| | | | | Blu-ray title index/playlist must be in the range 0-99999, otherwise an error will be returned
* stream_bluray: select title by playlistGravatar schnusch2016-10-17
| | | | | Blu-ray titles can now be selected by playlist number like this: bd://mpls/[playlist]
* stream_file: don't use poll() on directoriesGravatar wm42016-10-14
| | | | | | | | | | POSIX leaves poll() behavior on directories unspecified. While on Linux, it seems to behave the same way as regular files (always return immediately), this is not guaranteed. At least with OSX 10.12, it seems to wait, which essentially means that opening directories will "hang". Fixes #3530 and #3649.
* stream_libarchive: add some more points at which reading can be stoppedGravatar wm42016-10-01
|
* stream_lavf: check seekable flag correctlyGravatar wm42016-09-27
| | | | | | AVIOContext.seekable is actually a bitfield. Currently, it has only AVIO_SEEKABLE_NORMAL defined, but it might be extended with a hint for non-byte seekability. Thus we should check it correctly.
* stream_lavf: fix determining seekabilityGravatar wm42016-09-26
| | | | | | | | | | | | | | | | | | | | demux_lavf.c forces seek to being determined as supported if STREAM_CTRL_HAS_AVSEEK is returned as success. But it always succeeds with current FFmpeg versions. (Seems like Libav commit cae448cf broke this in early 2016.) Now we can't determine via private API whether the underlying protocol supports read_seek anymore. The affected protocols (mostly rtmp) also set seekable=0, meaning they signal they're not seekable, even though read_seek would work. (My guess is that this can't be fixed because even though seekable is in theory a combination of elaborate flags [of which only 1 is defined, AVIO_SEEKABLE_NORMAL], a seekable!=0 always means it's byte-seekable in some way.) So the FFmpeg API is being garbage _again_, and all what we can do is determining this via protocol name and a whitelist. Should fix the behavior reported in #1701.
* stream/stream_lavf: user-agent option is deprecatedGravatar RiCON2016-09-18
| | | | | | There was both user-agent and user_agent options, the former is deprecated in FFmpeg/FFmpeg@27714b462 master. Libav uses both forms. This avoids constant `[ffmpeg] http: the user-agent option is deprecated, please use user_agent option` warnings using ytdl_hook.
* stream_cb: don't add "*://" to protocol listGravatar wm42016-09-10
| | | | | | | | | --list-protocol was printing a *:// entry, which looked strange at best. The "*" protocol was used to always match everything, so stream_cb.c could hook in custom protocols with a prefix chosen by the API user. Change it instead so that an empty protocol list means "match all", which also gets rid of the special-cased "*" entry.
* stream, demux, config: remove some dead/unneeded option-related codeGravatar wm42016-09-09
| | | | | | | | | | This has all been made unnecessary recently. The change not to copy the global option struct in particular can be made because now nothing accesses the global options anymore in the demux and stream layers. Some code that was accidentally added/changed in commit 5e30e7a0 is also removed, because it was simply committed accidentally, and was never used.
* stream_cdda: remove weird option parsing stuffGravatar wm42016-09-09
| | | | | | | | | | Mostly untested. This is not compatible. It removes the URL fields for track range and cdrom speed (what did this even do). The device is not not to be prefixed with an additional "/" if it's put into the URL. I can't be bothered to keep these things compatible, just rip your damn CDs instead.
* tv: remove weird option parsing stuffGravatar wm42016-09-09
| | | | Mostly untested.
