Justin Ruggles	56f22b7e16	pcmenc: set frame_size to 0. This indicates that the actual frame size is based on the buf_size passed to avcodec_encode_audio().	13 years ago
Justin Ruggles	82390f57d1	avcodec: add GSM parser The WAVE demuxer returns packets with many blocks per frame, which needs to be parsed into single blocks. This has a side-effect of fixing the timestamps.	13 years ago
Diego Biurrun	5ea20630b4	Fix a bunch of platform name and other typos.	13 years ago
Janne Grunau	f6a152db11	threads: add CODEC_CAP_AUTO_THREADS for libvpx and xavs	13 years ago

Janne Grunau	3ab7700018	mpegvideo: claim ownership of referenced pictures Under certain conditions pictures could be released before they were returned with frame-threading. Broken mv computation in the upcoming rv34 frame-threading patch was caused by this. To prevent contexts from running out of available pictures the loop releasing "unused" pictures has to be run for B frames too.	13 years ago
Alex Converse	17ce52912f	aacsbr: prevent out of bounds memcpy(). Fixes Libav Bug 195. This doesn't make the code handle sample rate or upsample/downsample change properly but this is still a good sanity check. Based on change by Michael Niedermayer.

Diego Biurrun	1ef8ff4534	cabac: remove put_cabac_u/ueg from cabac-test. The functions are not used in any part of Libav, therefore testing them in the cabac-test is unnecessary. Since this makes them unused, remove the functions.	13 years ago

Justin Ruggles	07837e4158	avcodec: fix avcodec_encode_audio() documentation. the previous documentation indicated how many bytes are read from the input, not how many samples are read.	13 years ago

Justin Ruggles	77c5b66cbe	g722enc: set frame_size, and also handle an odd number of input samples The fate reference is updated because the previous test skipped a sample in each encode() call due each input frame having an odd number of samples.	13 years ago

Janne Grunau	f907615f08	parsers: initialize MpegEncContext.slice_context_count to 1 The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly) a MpegEncContext in their private context.
