audio/out: switch to channel map 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.

#include "audio/chmap.h"
audio: don't write decoded audio format to sh_audio sh_audio is supposed to contain file headers, not whatever was decoded. Fix this, and write the decoded format to separate fields in the decoder context, the dec_audio.decoded field. (Note that this field is really only needed to communicate the audio format from decoder driver to the generic code, so no other code accesses it.)

Rename directories, move files (step 2 of 2) 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.)

audio: switch output to mp_audio_buffer Replace the code that used a single buffer with mp_audio_buffer. This also enables non-interleaved output operation, although it's still disabled, and no AO supports it yet.

core: redo how codecs are mapped, remove codecs.conf Use codec names instead of FourCCs to identify codecs. Rewrite how codecs are selected and initialized. Now each decoder exports a list of decoders (and the codec it supports) via add_decoders(). The order matters, and the first decoder for a given decoder is preferred over the other decoders. E.g. all ad_mpg123 decoders are preferred over ad_lavc, because it comes first in the mpcodecs_ad_drivers array. Likewise, decoders within ad_lavc that are enumerated first by libavcodec (using av_codec_next()) are preferred. (This is actually critical to select h264 software decoding by default instead of vdpau. libavcodec and ffmpeg/avconv use the same method to select decoders by default, so we hope this is sane.) The codec names follow libavcodec's codec names as defined by AVCodecDescriptor.name (see libavcodec/codec_desc.c). Some decoders have names different from the canonical codec name. The AVCodecDescriptor API is relatively new, so we need a compatibility layer for older libavcodec versions for codec names that are referenced internally, and which are different from the decoder name. (Add a configure check for that, because checking versions is getting way too messy.) demux/codec_tags.c is generated from the former codecs.conf (minus "special" decoders like vdpau, and excluding the mappings that are the same as the mappings libavformat's exported RIFF tables). It contains all the mappings from FourCCs to codec name. This is needed for demux_mkv, demux_mpg, demux_avi and demux_asf. demux_lavf will set the codec as determined by libavformat, while the other demuxers have to do this on their own, using the mp_set_audio/video_codec_from_tag() functions. Note that the sh_audio/video->format members don't uniquely identify the codec anymore, and sh->codec takes over this role. Replace the --ac/--vc/--afm/--vfm with new --vd/--ad options, which provide cover the functionality of the removed switched. Note: there's no CODECS_FLAG_FLIP flag anymore. This means some obscure container/video combinations (e.g. the sample Film_200_zygo_pro.mov) are played flipped. ffplay/avplay doesn't handle this properly either, so we don't care and blame ffmeg/libav instead.

struct mp_decoder_list;
audio: move ready-for-ao data buffer from decoder to AO Move the buffer storing audio data ready to be fed to the audio output driver from the audio decoder object to the AO object. This will help encoding code deal with end of input, and may also be useful to improve other general gapless audio behavior (as AOs which do not accept chunks smaller than a certain size may keep them in the buffer while the decoder changes). Less data may be dropped now when changing audio filters or switching timeline parts.

audio: move decoder context from sh_audio into new struct Move all state that basically changes during decoding or is needed in order to manage decoding itself into a new struct (dec_audio). sh_audio (defined in stheader.h) is supposed to be the audio stream header. This should reflect the file headers for the stream. Putting the decoder context there is strange design, to say the least.

audio: ignore (some) decoding errors on initialization It probably happens relatively often that the first packet (or even the first N packets) of a stream will fail to decode, but decoding will eventually succeed at a later point. Before commit 261506e3, this was handled by an explicit retry loop (although this was also for other purposes), but with then was changed to abort on the first error. This makes it impossible to decode some audio streams. Change this so that errors are ignored for the first 50 packets, which should make it equivalent to the old code.

int init_retries;
audio: make decoders output refcounted frames 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 playback restart and resyncing This commit makes audio decoding non-blocking. If e.g. the network is too slow the playloop will just go to sleep, instead of blocking until enough data is available. For video, this was already done with commit 7083f88c. For audio, it's unfortunately much more complicated, because the audio decoder was used in a blocking manner. Large changes are required to get around this. The whole playback restart mechanism must be turned into a statemachine, especially since it has close interactions with video restart. Lots of video code is thus also changed. (For the record, I don't think switching this code to threads would make this conceptually easier: the code would still have to deal with external input while blocked, so these in-between states do get visible [and thus need to be handled] anyway. On the other hand, it certainly should be possible to modularize this code a bit better.) This will probably cause a bunch of regressions.

cosmetics: rename video/audio reset functions These used the suffix _resync_stream, which is a bit misleading. Nothing gets "resynchronized", they really just reset state. (Some audio decoders actually used to "resync" by reading packets for resuming playback, but that's not the case anymore.) Also move the function in dec_video.c to the top of the file.
