* avcodec: add GSM parserJustin Ruggles2012-01-11
| | | | | 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.
* Fix a bunch of platform name and other typos.Diego Biurrun2012-01-11

* threads: add CODEC_CAP_AUTO_THREADS for libvpx and xavsJanne Grunau2012-01-11

* rv34: frame-level multi-threadingJanne Grunau2012-01-10

* mpegvideo: claim ownership of referenced picturesJanne Grunau2012-01-10
| | | | | | | | | 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.
* aacsbr: prevent out of bounds memcpy().Alex Converse2012-01-10
| | | | | | | | | | | 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. Signed-off-by: Alex Converse <alex.converse@gmail.com>

* rv34: use get_bits_left()Janne Grunau2012-01-10
| | | | | It is not necessary to store the bit stream length in a RV34DecContext field.
* bmpdec: support for rgb444 with bitfields compressionPaul B Mahol2012-01-10

| | | | Fixes al_sbr_cm_48_5.1.mp4.
* cabac: remove put_cabac_u/ueg from cabac-test.Diego Biurrun2012-01-09
| | | | | 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.

* avcodec: fix avcodec_encode_audio() documentation.Justin Ruggles2012-01-07
| | | | | the previous documentation indicated how many bytes are read from the input, not how many samples are read.

|
* g722enc: set frame_size, and also handle an odd number of input samplesJustin Ruggles2012-01-07
| | | | | 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.

* parsers: initialize MpegEncContext.slice_context_count to 1Janne Grunau2012-01-06
| | | | | | | | | The mpeg4 video, H264 and VC-1 parser hold (directly or indirectly) a MpegEncContext in their private context. Since they do not call the common mpegvideo init function slice_context_count has explicitly set to 1. Prevents a null pointer dereference in the h264 parser and fixes bug 193.
* truemotion2: check size before GetBitContext initialisationJanne Grunau2012-01-05
