* ad_spdif: Fix crash when spdif muxer is not availableGravatar Michael Forney2016-12-11
| | | | | | | Currently, if init_filter fails after lavf_ctx is allocated, uninit is called which frees lavf_ctx, but doesn't clear the pointer in spdif_ctx. So, on the next call of decode_packet, it thinks it is already initialized and uses it, resulting in a crash on my system.
* Remove compatibility thingsGravatar wm42016-12-07
| | | | | | Possible with bumped FFmpeg/Libav. These are just the simple cases.
* ao_alsa: print certain ALSA errors as string instead as numberGravatar wm42016-12-07
|
* ao_wasapi: log return code when probing audio formatsGravatar wm42016-11-30
| | | | | | | | | We log a large number of formats, but we rarely log the result of the probing. Change this. The logic in try_format_exclusive() changes slightly, but should be equivalent. EXIT_ON_ERROR() checks for FAILED(), which should be exclusive to SUCCEEDED().
* ao_wasapi_utils: remove unused variableGravatar pavelxdd2016-11-27
| | | | | Introduced in 1a2319f3e4cc42c680e2fd3ba30022c7a9adf3fe Produced a warning during compilation on Windows.
* options: remove deprecated sub-option handling for --vo and --aoGravatar wm42016-11-25
| | | | | | | | Long planned. Leads to some sanity. There still are some rather gross things. Especially g_groups is ugly, and a hack that can hopefully be removed. (There is a plan for it, but whether it's implemented depends on how much energy is left.)
* audio/out/push: play silence on --audio-stream-silenceGravatar wm42016-11-24
| | | | | | | | | | | | | | | | | | | Until now, this was only implemented for ao_alsa and AOs not using push.c. ao_alsa.c relied on enabling funny underrun semantics for avoiding resets on lower levels, while other AOs using push.c didn't do anything. Change this and at least make push.c copy silent data to the AO. This still isn't perfect as keeping track of how much silence was played when seems complex, so we don't do it. The consequence is that frame-stepping will essentially randomize the A/V offset (it'll recover immediately when unpausing, but still ugly). Also, in order to empty the currently buffered audio on seeks etc., we still call ao_driver->reset and so on, so the AO driver will still need to handle this specially. The intent is to make behavior with ALSA less weird (for one we can remove the code in ao_alsa.c that tries to trigger an initial underflow). Also might help with #3754.
* audio: fix --audio-stream-silence with ao_wasapiGravatar wm42016-11-21
| | | | | Seems like wasapi will restart the HDMI stream if resume is called during playback.
* audio: fix --audio-stream-silence with ao_alsaGravatar wm42016-11-21
| | | | | | | ao_alsa.c calls this before the common code sets ao->sstride. Other than this, I'm still not sure whether this works. Seems like no, or depends.
* ao_alsa: explicitly add default device manuallyGravatar wm42016-11-14
| | | | | | | | | | | | | | The "default" entry (which is and always was mpv/mplayer's default) does not have a description set in the ALSA API. (While "sysdefault" strangely has.) Instead of an empty description, this should show something nice, so reuse the ao.c code for naming default devices (see previous commit). It's still a bit ugly that audio-device-list will have a default entry for "Autoselect device" and "Default (alsa)", but then again we probably want to allow the user to force ALSA (i.e. prevent fallbacks to other AOs) just because ALSA is so flaky and makes this a legitimate feature.
* audio: make empty device ID mean default deviceGravatar wm42016-11-14
| | | | | | | | | This will make it easier for AOs to add explicit default device entries. (See next commit.) Hopefully this change doesn't lead accidentally to bogus "Default" entries to appear, but then it can only happen if the device ID is empty, which would mean the underlying audio API returned bogus entries.
* audio: avoid returning audio-device-list entries without descriptionGravatar wm42016-11-14
| | | | | | Use the device name as fallback. This is ugly, but still better than skipping the description entirely. This can be an issue on ALSA, where the API can return entries without proper description.
* dec_video, dec_audio: avoid full reinit on switches to the same segmentGravatar wm42016-11-09
| | | | | | Same deal as with the previous commit. (Unfortunately, this code is still duplicated.)
* ao_alsa: fill unused ALSA channels with silenceGravatar wm42016-11-08
| | | | | | | | | | This happens when ALSA gives us more channels than we asked for, for whatever reasons. It looks like this wasn't handled correctly. The mpv and ALSA channel counts could mismatch, which would lead to UB. I couldn't actually trigger this case, though. I'm fairly sure that drivers or plugins exist that do it anyway. (Inofficial ALSA motto: if it can be broken, then why not break it?)
* ao_alsa: strictly disable chmap use for mono/stereoGravatar wm42016-11-08
| | | | | | | | | | If the input is already mono or stereo, or if channel map selection results in mono or stereo, then disable further use of the champ ALSA API (or rather, stop trusting its results). Then we behave like a simple application that only wants to output mono or stereo. See #3045 and #2905. I couldn't actually test these cases, but this commit is supposed to fix them.
* ao_alsa: _really_ disable chmap API use in cases where we shouldGravatar wm42016-11-08
| | | | | | | | | | | set_chmap() skipped _setting_ the ALSA chmap if chmap use was requested to be disabled by setting dev_chmap.num=0 by the caller, but it still queried the current ALSA channel map. We don't trust it that much, so disable that as well. But we still query and log it, because that could be helpful for debugging. Otherwise we could skip the entire set_chmap() call in these cases.
* ao_alsa: slightly better debug loggingGravatar wm42016-11-08
| | | | | | | Try to make it more compact, and also always list the reordered layout, but only if it's actually different. Should be the same functionally.
* audio/out: add AudioUnit output driver for iOSGravatar Aman Gupta2016-11-01

* ad_lavc, vd_lavc: fix a recent libavcodec deprecation warningGravatar wm42016-10-17
| | | | | | | | | | | | | | Both AVFrame.pts and AVFrame.pkt_pts have existed for a long time. Until now, decoders always returned the pts via the pkt_pts field, while the pts field was used for encoding and libavfilter only. Recently, pkt_pts was deprecated, and pts was switched to always carry the pts. This means we have to be careful not to accidentally use the wrong field, depending on the libavcodec version. We have to explicitly check the version numbers. Of course the version numbers are completely idiotic, because idiotically the pkg-config and library names are the same for FFmpeg and Libav, so we have to deal with this explicitly as well.
* ao_alsa: try to fallback to "hdmi" before "iec958" for spdifGravatar wm42016-10-07
| | | | | | | | | | | | | If the "default" device refuses to be opened as spdif device (i.e. it errors due to the AES0 etc. parameters), we were falling back to the iec958 device. This is needed on some systems for smooth operation with PCM vs. spdif. Now change it to try "hdmi" before "iec958", which supposedly helps in other situations. Better suggestions welcome. Apparently kodi does this too, although I didn't check directly.
* audio/out: prevent underruns with spdif under certain conditionsGravatar wm42016-10-04
| | | | | | | | | | | | | | | | | The player tries to avoid splitting frames with spdif (sample alignment stuff). This can in certain corner cases with certain drivers lead to the situation that ao_get_space() returns a number higher than 0 and lower than the audio frame size. The playloop will round this down to 0 bytes and do nothing, leading to a missed wakeup. This can lead to underruns or playback completely getting stuck. It can be reproduced by playing AC3 passthrough with no video and: --ao=null --ao-null-buffer=0.256 --ao-null-outburst=6100 This commit attempts to fix it by allowing the playloop to write some additional data (to get a complete frame), that will be buffered within the AO ringbuffer even if the audio device doesn't want it.
* audio: dump timestamp differenceGravatar wm42016-10-02
| | | | | Can help to analyze timestamp jitter or seeing completely bogus timestamps.
* win32: build with -DINITGUIDGravatar James Ross-Gowan2016-09-28
| | | | | | | | | | | | We always want to use __declspec(selectany) to declare GUIDs, but manually including <initguid.h> in every file that used GUIDs was error-prone. Since all <initguid.h> does is define INITGUID and include <guiddef.h>, we can remove all references to <initguid.h> and just compile with -DINITGUID to get the same effect. Also, this partially reverts 622bcb0 by re-adding libuuid.a to the build, since apparently some GUIDs (such as GUID_NULL) are not declared in the source file, even when INITGUID is set.
* ao_openal: enable building on OSXGravatar Josh de Kock2016-09-21
| | | | Signed-off-by: Josh de Kock <josh@itanimul.li>
* af_pan: fix typoGravatar Hector Martin2016-09-19
| | | | | | | | | This was in the parser code all along. As far as I can tell, *cp was intended. There is no need to check cp for NULL (nor does it make any sense to do so every time around the loop) for AF_CONTROL_COMMAND. However, s->matrixstr can be NULL, so checking for that separately is in order.
* af_rubberband: default to channels=togetherGravatar Hector Martin2016-09-19
| | | | | | | | For stereo and typical L/R-first channel arrangements, this avoids undesirable phasing artifacts, especially obvious when speed is changed and then reset. Without this, there is a very audible change in the stereo field even when librubberband is no longer actually making any speed changes.
* af_rubberband: add af-command and option to change the pitchGravatar Hector Martin2016-09-19
| | | | | This allows both fixed and dynamic control over the audio pitch using librubberband, which was previously not exposed to the user.
* af_pan: add af-command support to change the matrixGravatar Hector Martin2016-09-19
| | | | | This allows for seamless changes in the downmixing matrix without having to reinitialize the filter chain.
* af_pan: coding style fixesGravatar Hector Martin2016-09-19
|
* options: simplify M_OPT_EXITGravatar wm42016-09-17
| | | | | | | | | | | | | There were multiple values under M_OPT_EXIT (M_OPT_EXIT-n for n>=0). Somehow M_OPT_EXIT-n either meant error code n (with n==0 no error?), or the number of option valus consumed (0 or 1). The latter is MPlayer legacy, which left it to the option type parsers to determine whether an option took a value or not. All of this was changed in mpv, by requiring the user to use explicit syntax ("--opt=val" instead of "-opt val"). In any case, the n value wasn't even used (anymore), so rip this all out. Now M_OPT_EXIT-1 doesn't mean anything, and could be used by a new error code.
* player, ao, vo: don't call mp_input_wakeup() directlyGravatar wm42016-09-16
| | | | | | | | | | | | | Currently, calling mp_input_wakeup() will wake up the core thread (also called the playloop). This seems odd, but currently the core indeed calls mp_input_wait() when it has nothing more to do. It's done this way because MPlayer used input_ctx as central "mainloop". This is probably going to change. Remove direct calls to this function, and replace it with mp_wakeup_core() calls. ao and vo are changed to use opaque callbacks and not use input_ctx for this purpose. Other code already uses opaque callbacks, or has legitimate reasons to use input_ctx directly (such as sending actual user input).
* ao_rsound: fix compilationGravatar wm42016-09-07
| | | | Probably fixes #3501.
* ao_pcm: remove some useless messagesGravatar wm42016-09-07
| | | | | | The first one is printed even if the user disabled video (or there's no video), so just remove it. The second one uses deprecated sub-option syntax, so remove that as well.
* osdep: rename atomics.h to atomic.hGravatar wm42016-09-07
| | | | | The standard header is stdatomic.h, so the extra "s" freaks me out every time I look at it.
* audio/out: deprecate "exclusive" sub-optionsGravatar wm42016-09-05
| | | | | | | And introduce a global option which does this. Or more precisely, this deprecates the global wasapi and coreaudio options, and adds a new one that merges their functionality. (Due to the way the sub-option deprecation mechanism works, this is simpler.)
* audio/out: deprecate device sub-optionsGravatar wm42016-09-05
| | | | | We have --audio-device, which can force the device. Also add something describing to this extent to the manpage.
* options: deprecate suboptions for the remaining AO/VOsGravatar wm42016-09-05
|
* options: add automagic hack for handling sub-option deprecationsGravatar wm42016-09-05
| | | | | | | | | | | | | | | | | I decided that it's too much work to convert all the VO/AOs to the new option system manually at once. So here's a shitty hack instead, which achieves almost the same thing. (The only user-visible difference is that e.g. --vo=name:help will list the sub-options normally, instead of showing them as deprecation placeholders. Also, the sub-option parser will verify each option normally, instead of deferring to the global option parser.) Another advantage is that once we drop the deprecated options, converting the remaining things will be easier, because we obviously don't need to add the compatibility hacks. Using this mechanism is separate in the next commit to keep the diff noise down.
* ao_jack: move to global optionsGravatar wm42016-09-05
|
* options: add a mechanism to make sub-option replacement slightly easierGravatar wm42016-09-05
| | | | | | | | Instead of requiring each VO or AO to manually add members to MPOpts and the global option table, make it possible to register them automatically via vo_driver/ao_driver.global_opts members. This avoids modifying options.c/options.h every time, including having to duplicate the exact ifdeffery used to enable a driver.
* ao_alsa: change sub-options to global optionsGravatar wm42016-09-02
| | | | | | Same deal as with vo_opengl. Also edit the outdated information about multichannel output a little.
* m_config: add helper function for initializing af/ao/vf/vo suboptionsGravatar wm42016-09-02
| | | | | | | | Normally I'd prefer a bunch of smaller functions with fewer parameters over a single function with a lot of parameters. But future changes will require messing with the parameters in a slightly more complex way, so a combined function will be needed anyway. The now-unused "global" parameter is required for later as well.
* vo, ao: disable positional parameter suboptionsGravatar wm42016-09-01
| | | | | | | | | | | | | | | | Positional parameters cause problems because they can be ambiguous with flag options. If a flag option is removed or turned into a non-flag option, it'll usually be interpreted as value for the first sub-option (as positional parameter), resulting in very confusing error messages. This changes it into a simple "option not found" error. I don't expect that anyone really used positional parameters with --vo or --ao. Although the docs for --ao=pulse seem to encourage positional parameters for the host/sink options, which means it could possibly annoy some PulseAudio users. --vf and --af are still mostly used with positional parameters, so this must be a configurable option in the option parser.
* vd_lavc, ad_lavc: set pkt_timebase, not time_baseGravatar wm42016-08-29
| | | | | | | | | These are different AVCodecContext fields. pkt_timebase is the correct one for identifying the unit of packet/frame timestamps when decoding, while time_base is for encoding. Some decoders also overwrite the time_base field with some unrelated codec metadata. pkt_timebase does not exist in Libav, so an #if is required.
* ad_lavc: actually tell decoder about the timebaseGravatar wm42016-08-23
| | | | Essentially forgotten in commit 05e4df3f.
* ao_alsa: log if retrieving supported channel maps failsGravatar wm42016-08-22
| | | | It's a sign that the driver doesn't implement the channel map API.
* af_lavrresample: better swr reinitializationGravatar Paul B Mahol2016-08-20
|
* af_lavrresample: fix error if resampler could not be recreatedGravatar wm42016-08-19
| | | | | | | | There are situations where the resampler is destroyed and recreated during playback. If recreating the resampler unexpectedly fails, the filter function is supposed to return an error. This wasn't done correctly, because get_out_samples() accessed the resampler before the check. Move the check up to fix this.
* video/audio: always provide "proper" timestamps to libavcodecGravatar wm42016-08-19
| | | | | | | | | | | | | | | | | | | Instead of passing through double float timestamps opaquely, pass real timestamps. Do so by always setting a valid timebase on the AVCodecContext for audio and video decoding. Specifically try not to round timestamps to a too coarse timebase, which could round off small adjustments to timestamps (such as for start time rebasing or demux_timeline). If the timebase is considered too coarse, make it finer. This gets rid of the need to do this specifically for some hardware decoding wrapper. The old method of passing through double timestamps was also a bit questionable. While libavcodec is not supposed to interpret timestamps at all if no timebase is provided, it was needlessly tricky. Also, it actually does compare them with AV_NOPTS_VALUE. This change will probably also reduce confusion in the future.
* audio: improve aspects of EOF handlingGravatar wm42016-08-18
| | | | | | | | | | | The code actually kept going out of EOF mode into resync mode back into EOF mode when the playloop had to wait after an audio EOF caused by the endpts. This would break seamless looping (as added by the next commit). Apply endpts earlier, to ensure the filter_audio() function always returns AD_EOF in this case. The idiotic ao_buffer makes this an amazing pain in the ass.
