* audio: redo internal AO APIwm42020-06-011-60/+30
| | | | | | | | | | | | | | | | | | | | | | | | | This affects "pull" AOs only: ao_alsa, ao_pulse, ao_openal, ao_pcm, ao_lavc. There are changes to the other AOs too, but that's only about renaming ao_driver.resume to ao_driver.start. ao_openal is broken because I didn't manage to fix it, so it exits with an error message. If you want it, why don't _you_ put effort into it? I see no reason to waste my own precious lifetime over this (I realize the irony). ao_alsa loses the poll() mechanism, but it was mostly broken and didn't really do what it was supposed to. There doesn't seem to be anything in the ALSA API to watch the playback status without polling (unless you want to use raw UNIX signals). No idea if ao_pulse is correct, or whether it's subtly broken now. There is no documentation, so I can't tell what is correct, without reverse engineering the whole project. I recommend using ALSA. This was supposed to be just a simple fix, but somehow it expanded scope like a train wreck. Very high chance of regressions, but probably only for the AOs listed above. The rest you can figure out from reading the diff.
* audio: remove ao_driver.drainwm42020-05-271-11/+0
| | | | | | | | | | The recent change to the common code removed all calls to ->drain. It's currently emulated via a timed sleep and polling ao_eof_reached(). That is actually fallback code for AOs which lacked draining. I could just readd the drain call, but it was a bad idea anyway. My plan to handle this better is to require the AO to signal a underrun, even if AOPLAY_FINAL_CHUNK is not set. Also reinstate not possibly waiting for ao_lavc.c. ao_pcm.c did not have anything to handle this; whatever.
* options: change option macros and all option declarationswm42020-03-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change all OPT_* macros such that they don't define the entire m_option initializer, and instead expand only to a part of it, which sets certain fields. This requires changing almost every option declaration, because they all use these macros. A declaration now always starts with {"name", ... followed by designated initializers only (possibly wrapped in macros). The OPT_* macros now initialize the .offset and .type fields only, sometimes also .priv and others. I think this change makes the option macros less tricky. The old code had to stuff everything into macro arguments (and attempted to allow setting arbitrary fields by letting the user pass designated initializers in the vararg parts). Some of this was made messy due to C99 and C11 not allowing 0-sized varargs with ',' removal. It's also possible that this change is pointless, other than cosmetic preferences. Not too happy about some things. For example, the OPT_CHOICE() indentation I applied looks a bit ugly. Much of this change was done with regex search&replace, but some places required manual editing. In particular, code in "obscure" areas (which I didn't include in compilation) might be broken now. In wayland_common.c the author of some option declarations confused the flags parameter with the default value (though the default value was also properly set below). I fixed this with this change.
* audio/out: rip out old unused app/softvolume reportingwm42019-10-111-2/+0
| | | | | | | | | | | This was all dead code. Commit 995c47da9a (over 3 years ago) removed all uses of the controls. It would be nice if AOs could apply a linear gain volume, that only affects the AO's audio stream for low-latency volume adjust and muting. AOCONTROL_HAS_SOFT_VOLUME was supposed to signal this, but to use it, we'd have to thoroughly check whether it really uses the expected semantics, so there's really nothing useful left in this old code.
* Revert "ao_openal: enable building on OSX"Michael Hoang2018-08-261-14/+0
| | | | | | This reverts commit af6126adbe61fb2b6cc780025246d33df93072e6. Apple's OpenAL support is ridiculously out of date, revert back to just using OpenAL Soft on macOS (fixes #4645).
* ao_openal: document the muted↔gain conversionJan Ekström2018-04-151-0/+3
| | | | This struck me as odd for a moment, so adding a comment.
* ao/openal: Add option to set buffering characteristicsLAGonauta2018-04-151-23/+62
| | | | | | | | | One can now set the number of buffers and the buffer size. This can reduce the CPU usage and the total latency stays mostly the same. As there are sync mechanisms the A/V sync continue intact and working. It also modifies 6.1 channel order, as per OpenAL spec and add AOPLAY_FINAL_CHUNK support
* ao/openal: Add better sample format and channel layout selectionLAGonauta2018-04-151-139/+73
| | | | Also re-added floating-point support.
* ao/openal: Add OpenAL Soft extension to get the correct latencyLAGonauta2018-04-151-1/+16
| | | | | | | | OpenAL Soft's AL_SOFT_source_latency extension allows one to correctly get the device output latency, facilitating the syncronization with video. Also added a simpler generic fallback that does not take into account latency of the device.
* ao/openal: Add support for direct channels outputLAGonauta2018-04-151-0/+10
| | | | | | | Uses OpenAL Soft's AL_DIRECT_CHANNELS_SOFT extension and can be controlled through a new CLI option, --openal-direct-channels. This allows one to send the audio data direrctly to the desired channel without effects applied.
* ao/openal: Add hardware mute supportLAGonauta2018-04-151-0/+12
| | | | | While the volume is set on the listener, mute is set on the sound source. Seemed easier that way.
* ao/openal: Use only one source for audio outputLAGonauta2018-04-151-52/+153
| | | | Floating point audio not supported on this commit.
* audio: fix annyoing af_get_best_sample_formats() definitionwm42018-01-251-1/+1
| | | | | | | | | | | | | | | | The af_get_best_sample_formats() function had an argument of int[AF_FORMAT_COUNT], which is slightly incorrect, because it's 0 terminated and should in theory have AF_FORMAT_COUNT+1 entries. It won't actually write this many formats (since some formats are fundamentally incompatible), but it still feels annoying and incorrect. So fix it, and require that callers pass an AF_FORMAT_COUNT+1 array. Note that the array size has no meaning in C function arguments (just another issue with C static arrays being weird and stupid), so get rid of it completely. Not changing the af_lavcac3enc use, since that is rewritten in another branch anyway.
* audio/out: require AO drivers to report period size and correct bufferwm42017-06-251-0/+1
| | | | | | | | | | | | | | | | Before this change, AOs could have internal alignment, and play() would not consume the trailing data if the size passed to it is not aligned. Change this to require AOs to report their alignment (via period_size), and make sure to always send aligned data. The buffer reported by get_space() now always has to be correct and reliable. If play() does not consume all data provided (which is bounded by get_space()), an error is printed. This is preparation for potential further AO changes. I casually checked alsa/lavc/null/pcm, the other AOs might or might not work.
* ao_openal: change license to LGPLwm42017-06-241-7/+7
| | | | All authors have agreed.
* ao_openal: kill off device listingwm42017-04-231-41/+1
| | | | | Probably helps with #4311. It surely is not the correct fix, of course. But ao_openal has no business of causing trouble anyway.
* options: remove deprecated sub-option handling for --vo and --aowm42016-11-251-1/+1
| | | | | | | | 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.)

* options: simplify M_OPT_EXITwm42016-09-171-1/+1
| | | | | | | | | | | | | 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.
* audio/out: deprecate device sub-optionswm42016-09-051-1/+2
| | | | | We have --audio-device, which can force the device. Also add something describing to this extent to the manpage.

* ao_openal: wipe out global context on init errorKevin Mitchell2016-01-181-0/+1
| | | | | Previously this would break all further attempts to init the driver after one had failed.

* ao_openal: fix virtual speaker positioningJustas Lavišius2015-11-181-10/+10
| | | | | | Place speakers in standard positions equidistant from the listener. use standard coordinate system
* ao_openal: accommodate more sample formatsKevin Mitchell2015-11-171-7/+44
| | | | | | Try and and choose the closest sample format to the one requested. fixes #2494

* audio/out: consistently use double return type for get_delaywm42014-11-091-2/+2
| | | | | ao_get_delay() returns double, but the get_delay callback still returned float.
* ao_openal: implement device listingwm42014-10-131-1/+16
|
* audio/out: remove old thingswm42014-09-061-1/+2
| | | | | | | | Remove the unnecessary indirection through ao fields. Also fix the inverted result of AOCONTROL_HAS_TEMP_VOLUME. Hopefully the change is equivalent. But actually, it looks like the old code did it wrong.
* audio/out: make draining a separate operationwm42014-03-091-9/+12
| | | | | | | | | | | | Until now, this was always conflated with uninit. This was ugly, and also many AOs emulated this manually (or just ignored it). Make draining an explicit operation, so AOs which support it can provide it, and for all others generic code will emulate it. For ao_wasapi, we keep it simple and basically disable the internal draining implementation (maybe it should be restored later). Tested on Linux only.
* audio/out: make ao struct opaquewm42014-03-091-0/+1
| | | | | | We want to move the AO to its own thread. There's no technical reason for making the ao struct opaque to do this. But it helps us sleep at night, because we can control access to shared state better.
* m_option: add mp_log callback to OPT_STRING_VALIDATE optionswm42013-12-211-5/+5
| | | | | And also convert a bunch of other code, especially ao_wasapi and ao_portaudio.
* Split mpvcore/ into common/, misc/, bstr/wm42013-12-171-1/+1
|
* Move options/config related files from mpvcore/ to options/wm42013-12-171-1/+1
| | | | | | | | | Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.
* ao_openal: support non-interleaved outputwm42013-11-121-18/+11
| | | | | | Since ao_openal simulates multi-channel audio by placing a bunch of mono-sources in 3D space, non-interleaved audio is a perfect match for it. We just have to remove the interleaving code.
* audio/out: prepare for non-interleaved audiowm42013-11-121-4/+5
| | | | | | | | | | | | | | | | | | | This comes with two internal AO API changes: 1. ao_driver.play now can take non-interleaved audio. For this purpose, the data pointer is changed to void **data, where data[0] corresponds to the pointer in the old API. Also, the len argument as well as the return value are now in samples, not bytes. "Sample" in this context means the unit of the smallest possible audio frame, i.e. sample_size * channels. 2. ao_driver.get_space now returns samples instead of bytes. (Similar to the play function.) Change all AOs to use the new API. The AO API as exposed to the rest of the player still uses the old API. It's emulated in ao.c. This is purely to split the commits changing all AOs and the commits adding actual support for outputting N-I audio.
* audio/out: remove useless info struct and redundant fieldswm42013-10-231-6/+2
|
* audio/out: do some mp_msg conversionswm42013-08-221-3/+3
| | | | | | | Use the new MP_ macros for some AOs instead of mp_msg. Not all AOs are converted, and some only partially. In some cases, some additional cosmetic changes are made.
* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-2/+2
| | | | Followup commit. Fixes all the files references.
* audio/out: remove options argument from init()wm42013-07-221-1/+1
| | | | Same as with VOs in the previous commit.
* ao_openal: use new option APIwm42013-07-211-42/+29
|
* audio/out: remove ao->outburst/buffersize fieldswm42013-06-161-2/+0
| | | | | | | | | | | | | | | The core didn't use these fields, and use of them was inconsistent accross AOs. Some didn't use them at all. Some only set them; the values were completely unused by the core. Some made full use of them. Remove these fields. In places where they are still needed, make them private AO state. Remove the --abs option. It set the buffer size for ao_oss and ao_dsound (being ignored by all other AOs), and was already marked as obsolete. If it turns out that it's still needed for ao_oss or ao_dsound, their default buffer sizes could be adjusted, and if even that doesn't help, AO suboptions could be added in these cases.
* audio/out: don't require AOs to set ao->bpswm42013-06-161-1/+0
| | | | | | | Some still do, because they use the value in other places of the init function. ao_portaudio is tricky and reads ao->bps in the stream thread, which might be started on initialization (not sure about that, but better safe than sorry).

* ao_openal: uncrustifywm42013-06-041-172/+185

* Replace calls to usec_sleep()wm42013-05-261-1/+1
| | | | | | This is just dumb sed replacement to mp_sleep_us(). Also remove the now unused usec_sleep() wrapper.
* audio/out: channel map selectionwm42013-05-121-5/+5
| | | | | | | | | Make all AOs use what has been introduced in the previous commit. Note that even AOs which can handle all possible layouts (like ao_null) use the new functions. This might be important if in the future ao_select_champ() possibly honors global user options about downmixing and so on.
* ao_openal: use channel map instead of ALSA fixed layoutwm42013-05-121-10/+31
| | | | | | | | | Now mpv's channel map is used to map each channel to a speaker. This allows in theory for playback of any layout for which ao_openal actually has a speaker defined. Also add the back-center (BC) speaker, which allows playback of 6.0 audio. Enabling more layouts by adding other speakers would be possible, but I'm not sure about the speaker positions.
* audio/out: switch to channel mapwm42013-05-121-20/+23
| | | | | | This actually breaks audio for 5/6/8 channels. There's no reordering done yet. The actual reordering will be done inside of af_lavrresample and has to be made part of the format negotiation.
* Rename directories, move files (step 2 of 2)wm42012-11-121-4/+4
| | | | | | | | | | | | Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)
* Rename directories, move files (step 1 of 2) (does not compile)wm42012-11-121-0/+280
Tis drops the silly lib prefixes, and attempts to organize the tree in a more logical way. Make the top-level directory less cluttered as well. Renames the following directories: libaf -> audio/filter libao2 -> audio/out libvo -> video/out libmpdemux -> demux Split libmpcodecs: vf* -> video/filter vd*, dec_video.* -> video/decode mp_image*, img_format*, ... -> video/ ad*, dec_audio.* -> audio/decode libaf/format.* is moved to audio/ - this is similar to how mp_image.* is located in video/. Move most top-level .c/.h files to core. (talloc.c/.h is left on top- level, because it's external.) Park some of the more annoying files in compat/. Some of these are relicts from the time mplayer used ffmpeg internals. sub/ is not split, because it's too much of a mess (subtitle code is mixed with OSD display and rendering). Maybe the organization of core is not ideal: it mixes playback core (like mplayer.c) and utility helpers (like bstr.c/h). Should the need arise, the playback core will be moved somewhere else, while core contains all helper and common code.
