* command: add af-command commandwm42016-01-221-0/+2
| | | | Similar to vf-command. Requested. Untested.
* audio: change downmix behavior, add --audio-normalize-downmixwm42016-01-201-0/+1
| | | | | | This is probably the 3rd time the user-visible behavior changes. This time, switch back because not normalizing seems to be the more expected behavior from users.
* audio/filter: remove reentrancy flagwm42015-09-201-5/+0
| | | | | | | | | | This flag was used by some filters and made sure none of these filters were inserted twice. This triggers only if the user explicitly tries to add multiple filters (and not e.g. due to auto-insertion), so at best this warned the user from doing something potentially pointless. At worst, it blocked some (mildly) legitimate use-cases. Get rid of it. Also see #2322.
* af_lavfi: implement af-metadata propertywm42015-09-111-0/+2
| | | | | | | Works like vf-metadata. Unfortunately requires some code duplication (even though it's not much). Fixes #2311.
* af: use generic statuc codeswm42015-09-111-7/+7
| | | | | | | The reason MPlayer traditionally duplicated them all over the place is that it wanted every component to be a self-contained library (e.g. audio filters were in "libaf"). But this is not necessarily helpful, and this change makes the following commit a bit simpler.
* af: move af_from_dB() function to af_volume.cwm42015-06-231-1/+0
| | | | | And also simplify it (it certainly had the most awkward API you could think of for such a simple function).
* af: restore detaching of PCM filters when using spdifwm42015-06-221-0/+2
| | | | | | Basically, af_fix_format_conversion() behaves stupid you insert a conversion filter that won't work, and adding back the conversion test function is the simplest fix to it.
* af: remove conversion filter searchwm42015-06-161-1/+0
| | | | | | This attempted to find a minimal filter graph for a format conversion involving multiple conversion filters. With the last 2 commits it becomes dead code - remove it.
* Update license headersMarcin Kurczewski2015-04-131-5/+4
| | | | Signed-off-by: wm4 <wm4@nowhere>
* audio: change a detail about filter insertionwm42015-04-071-1/+2
| | | | | | | | | | The af_add() function has a problem: if the inserted filter returns AF_DETACH during init, the function will have a dangling pointer. Until now this was avoided by making sure none of the used filters actually return AF_DETACH, but it's getting infeasible. Solve this by requiring passing an unique label to af_add(), which is then used instead of the pointer.
* af: remove unused functionswm42015-04-011-2/+0

* af: remove old filter compatibility hackwm42015-01-151-5/+0
|
* audio: use refcounted frames in the filter chainwm42015-01-131-4/+24
| | | | | | | | | | | | | | | | | | | The goal is switching the whole audio chain to using refcounted frames. This brings the architecture closer to FFmpeg, enables better integration with libavfilter, will reduce useless copying somewhat, and will probably allow better timestamp tracking. For now, every filter goes through a semi-awful wrapper in af_do_filter(), though. This will be fixed step by step, and the wrapper should eventually be removed. Another thing that will have to be done is improving the timestamp handling and avoiding extra copies for the AO. Some of the new code is rather similar to the video filter code (the core filter code basically just has types replaced). Such code duplication is normally very unwanted, but in this case there's probably no other choice. On the other hand, this code is pretty simple (even if somewhat tricky). Maybe there will be unified filter code in the future, but this is still far away.
* audio/filter: remove unused af_calc_filter_multiplier()wm42015-01-131-4/+0
| | | | | | | | | | | | The purpose of this function was to filter only as much audio input as needed to produce a certain amount of audio output. This could (in theory) avoid excessive buffering when e.g. changing playback speed with resampling. Use of this was already removed in commit 5fd8a1e0. No problems were experienced, so let's assume this feature is practically worthless. (Though it's possible that it was quite useful over a decade ago, or in some cornercases with evil files.)
* audio: make decoders output refcounted frameswm42014-11-101-1/+3
| | | | | | | | | | | | | | This rewrites the audio decode loop to some degree. Audio filters don't do refcounted frames yet, so af.c contains a hacky "emulation". Remove some of the weird heuristic-heavy code in dec_audio.c. Instead of estimating how much audio we need to filter, we always filter full frames. Maybe this should be adjusted later: in case filtering increases the volume of the audio data, we should try not to buffer too much filter output by reducing the input that is fed at once. For ad_spdif.c and ad_mpg123.c, we don't avoid extra copying yet - it doesn't seem worth the trouble.
* audio: change how filters are inserted on playback speed changeswm42014-11-101-0/+1
| | | | | | | | | | Use a pseudo-filter when changing speed with resampling, instead of somehow changing a samplerate somewhere. This uses the same underlying mechanism, but is a bit more structured and cleaner. It also makes some of the following changes easier. Since we now always use filters to change audio speed, move most of the work set_playback_speed() does to recreate_audio_filters().
* audio/filter: allow removing filters by labelwm42014-10-021-0/+3
| | | | | | | | Although the "af" command already could do this, it seems it's better to introduce a lower level mechanism for now. This avoids some messy issues, since that code would recursive call reinit_audio_chain(). To be used by the next commit.
* audio: refactor some aspects of filter chain setupwm42014-10-021-0/+2
| | | | | | | | | | | There's no real reason why audio_init_filter() should exist. Just use af_init or af_reinit directly. (We lose a useless message; the same information is printed in a quite close place with more details.) Requires less code, and the way the filter chain is marked as having failed to initialize allows just switching off audio instead of crashing if trying to insert a volume filter in mixer.c fails, and recreating the old filter chain fails too.
* audio: remove unused metadata fieldwm42014-07-211-2/+0
| | | | | This was used for replaygain at some point, until replaygain info was passed through explicitly.
* af: add replaygain_data field to af_stream and af_instanceAlessandro Ghedini2014-04-041-0/+2
| | | | Closes #664
* af: add metadata field to af_stream and af_instanceAlessandro Ghedini2014-03-131-0/+2
| | | | | | This allows to propagate metadata information to audio filters. Closes #632
* audio: mp_msg conversionswm42013-12-211-1/+4
|
* Reduce recursive config.h inclusions in headerswm42013-12-181-2/+0
| | | | | | In my opinion, config.h inclusions should be kept to a minimum. MPlayer code really liked including config.h everywhere, though, even in often used header files. Try to reduce this.
* 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.
* audio/filter: change filter callback signaturewm42013-12-051-2/+8
| | | | | | | | | The new signature is actually closer to how it actually works, and someone who is not familiar to the API and how it works might make fewer fatal mistakes with the new signature than the old one. Pretty weird. Do this to sneak in a flags parameter, which will later be used to flush remaining data of at least vf_lavfi.
* af: remove af->setup fieldwm42013-12-041-1/+0
| | | | Used to be used by filters that didn't use the option parser.
* af: remove legacy option parsing hackswm42013-12-041-1/+0
|
* options: add options that set defaults for af/vf/ao/vowm42013-12-011-1/+0
| | | | | | | | There are some use cases for this. For example, you can use it to set defaults of automatically inserted filters (like af_lavrresample). It's also useful if you have a non-trivial VO configuration, and want to use --vo to quickly change between the drivers without repeating the whole configuration in the --vo argument.
* audio: drop buffered filter data when seekingwm42013-11-181-0/+2
| | | | | This could lead to (barely) audible artifacts with --af=scaletempo and modified playback speed.
* audio/filter: remove unneeded AF_CONTROLs, convert to enumwm42013-11-181-1/+23
| | | | | | | | The AF control commands used an elaborate and unnecessary organization for the command constants. Get rid of all that and convert the definitions to a simple enum. Also remove the control commands that were not really needed, because they were not used outside of the filters that implemented them.
* af: cleanup documentation commentswm42013-11-181-132/+2
| | | | | | And by "cleanup", I mean "remove". Actually, only remove the parts that are redundant and doxygen noise. Move useful parts to the comment above the function's implementation in the C source file.
* audio/filter: fix mul/delay scale and valueswm42013-11-121-3/+4
| | | | | | | | | | | | | Before this commit, the af_instance->mul/delay values were in bytes. Using bytes is confusing for non-interleaved audio, so switch mul to samples, and delay to seconds. For delay, seconds are more intuitive than bytes or samples, because it's used for the latency calculation. We also might want to replace the delay mechanism with real PTS tracking inside the filter chain some time in the future, and PTS will also require time-adjustments to be done in seconds. For most filters, we just remove the redundant mul=1 initialization. (Setting this used to be required, but not anymore.)
* af: don't require filters to allocate af_instance->data, redo bufferswm42013-11-121-5/+1
| | | | | | | | | | | | | Allocate af_instance->data in generic code before filter initialization. Every filter needs af->data (since it contains the output configuration), so there's no reason why every filter should allocate and free it. Remove RESIZE_LOCAL_BUFFER(), and replace it with mp_audio_realloc_min(). Interestingly, most code becomes simpler, because the new function takes the size in samples, and not in bytes. There are larger change in af_scaletempo.c and af_lavcac3enc.c, because these had copied and modified versions of the RESIZE_LOCAL_BUFFER macro/function.
* af: remove a pointless macrowm42013-11-071-16/+1
| | | | | The code should be equivalent; a compatibility macro definition is left. (It should be mass-replaced later.)
* af: replace macros with too generic nameswm42013-10-261-21/+0
| | | | | | | | Defining names like min, max etc. in an often used header is not really a good idea. Somewhat similar to MPlayer svn commit 36491, but don't use libavutil, because that typically causes us sorrow.
* audio/filter: remove useless af_info fieldswm42013-10-231-2/+0
| | | | | | | Drop the author and comment fields. They were completely unused - not even printed in verbose mode, just dead weight. Also use designated initializers and drop redundant flags.
* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-2/+2
| | | | Followup commit. Fixes all the files references.
* audio/filter: use new option APIwm42013-07-221-36/+8
| | | | | | | | | | | | | Make the VF/VO/AO option parser available to audio filters. No audio filter uses this yet, but it's still a quite intrusive change. In particular, the commands for manipulating filters at runtime completely change. We delete the old code, and use the same infrastructure as for video filters. (This forces complete reinitialization of the filter chain, which hopefully isn't a problem for any use cases. The old code forced reinitialization too, but it could potentially allow a filter to cache things; e.g. consider loaded ladspa plugins and such.)
* audio: add some setters for mp_audio, and require filters to use themwm42013-05-121-20/+1
| | | | | | | | | | | | | | | | mp_audio has some redundant fields. Setters like mp_audio_set_format() initialize these properly. Also move the mp_audio struct to a the file audio.c. We can remove a mysterious line of code from af.c: in.format |= af_bits2fmt(in.bps * 8); I'm not sure if this was ever actually needed, or if it was some kind of "make it work" quick-fix that works against the way things were supposed to work. All filters etc. now set the format correctly, so if there ever was a need for this code, it's definitely gone.
* audio: add channel map APIwm42013-05-121-3/+2
| | | | | | | Unused, will be used in the following commits. Let chmap.h define the number of maximum channels, because that is most convenient.
* af: streamline format negotiationwm42013-04-131-1/+7
| | | | | | | | | | | | | Add dummy input and output filters to remove special cases in the format negotiation code (af_fix_format_conversion() etc.). The output of the filter chain is now negotiated in exactly the same way as normal filters. Negotiate setting the sample rate in the same way as other audio parameters. As a side effect, the resampler is inserted at the start of the filter chain instead of the end, but that shouldn't matter much, especially since conversion and channel mixing are conflated into the same filter (due to libavresample's API).
* options: remove --af-advwm42013-04-131-19/+0
| | | | | | | Anything this option did has been removed in the preceding 3 commits. Note that even though these options sounded like a good idea (like setting accuracy vs. speed tradeoffs), they were not really properly implemented.
* af: use af_lavrresample for format conversions, if possiblewm42013-04-131-0/+1
| | | | | | | | | | | | | Refactor to remove the duplicated format filter insertion code. Allow other format converting filters to be inserted on format mismatches. af_info.test_conversion checks whether conversion between two formats would work with the given filter; do this to avoid having to insert multiple conversion filters at once and such things. (Although this isn't ideal: what if we want to avoid af_format for some conversions? What if we want to split af_format in endian-swapping filters etc.?) Prefer af_lavrresample for conversions that it supports natively, otherwise let af_format handle the full conversion.
* af: remove automatically inserted filters on full reinitwm42013-04-131-2/+4
| | | | | | | | | | | | | | | | | | | | | | Make sure automatically inserted filters are removed on full reinit (they are re-added later if they are really needed). Automatically inserted filters were never explicitly removed, instead, it was expected that redundant conversion filters detach themselves. This didn't work if there were several chained format conversion filters, e.g. s16le->floatle->s16le, which could result from repeated filter insertion and removal. (format filters detach only if input format and output format are the same.) Further, the dummy filter (which exists only because af.c can't handle an empty filter chain for some reason) could introduce bad conversions due to how the format negotiation works. Change the code so that the dummy filter never takes part on format negotiation. (It would be better to fix format negotiation, but that would be much more complicated and would involving fixing all filters.) Simplify af_reinit() and remove the start audio filter parameter. This means format negotiation and filter initialization is run more often, but should be harmless.

* Rename directories, move files (step 2 of 2)wm42012-11-121-4/+3
| | | | | | | | | | | | 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/+349
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.
