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.

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.)

fdclose://123 will instruct mpv to close the file descriptor
when it is no longer needed (usually when playing finishes).

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.

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.

While subtly duplicating such checks happens a lot in this file, this
particular case can be easily factored into a function.

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.

Clearly the licensing situation isn't confusing enough.
I don't know why that guy insists on LGPLv3.
|
|
|
|
|
|
|
|
|
|
| |
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.

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.

One minor exception is 21a9221e7bb2 (patch by someone who wasn't asked),

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.)

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.

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.

Some fields (notably tv_channel_list) were left uninitialized,
potentially causing problems later on.

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.

"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.

This makes the player spam timestamp warnings. Return NOPTS instead.

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.

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.

Only FFmpeg supports them and they need to be in the format data://

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.

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.)

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: 2 duration: 00:00:50 (playlist: 00003.mpls)
should play the expected idx 1.

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".

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.

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.

|
|
|
|
|

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.

--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.

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.

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

instead.

Instead, parse manually. This is to get rid of the option API usages,
