2013-07-15indeo: Reject impossible FRAMETYPE_NULLLuca Barbato
A frame marked FRAMETYPE_NULL cannot be scalable and requires a previous frame successfully decoded. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

Trim some overly long lines.

The same is done already for qdelta. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-07-01indeo: use proper error codeLuca Barbato
2013-07-01indeo: Properly forward the error codesLuca Barbato
If the tile data size does not match the buffer size it did not return an AVERROR_INVALIDDATA causing futher corruption later. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-06-01indeo4: expand allowed quantiser rangeKostya Shishkov
Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping quantiser leads to incorrect quantisation and DC prediction on low-quality videos. This fixes bug 259.
2013-05-04avcodec: Add av_cold attributes to init functions missing themDiego Biurrun
2013-03-08ivi_common: do not call MC for intra frames when dc_transform is unsetAnton Khirnov

2012-12-14ivi_common: make some functions and tables static.Anton Khirnov
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.
2012-10-26ivi_common: Drop unused function parameter from decode_band()Diego Biurrun
2012-10-12Move av_reverse table to libavcodecDiego Biurrun

Fixes bogus uninitialized value compiler and coverity warnings.
2012-09-29indeo4/5: check empty tile size in decode_mb_info().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.
