2013-09-29xan: Use bytestream2 to limit reading to within the bufferMartin Storsjö

2013-03-08lavc decoders: work with refcounted frames.Anton Khirnov
2013-01-09xan: Convert to bytestream2Alexandra Khirnova

2013-01-06xan: return a meaningful error code.Anton Khirnov
2012-12-24xan: remove a trivially true if().Anton Khirnov
This function used to be shared with the xxan decoder, but that is not true anymore.
2012-12-05lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov
It's got_frame, not data size
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-10-25avutil: Move memcpy_backptr() to mem.cDiego Biurrun
The function is used elsewhere and does not belong with the LZO code.
2012-10-08Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov
2012-08-07Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov
2011-12-22Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun
The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.

2011-09-12Fixed size given to init_get_bits() in xan decoder.Laurent Aimar
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.

2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
