Michael Niedermayer	488383afd1	avformat/avidec: add mp2 to the list of exceptions instead of generally treating dshow_block_align==1 special Fixes Ticket4552 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Andreas Cadhalpun	4d0ee4962b	avi: Validate sample_size And either error out or set it to 0 if it is negative. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Michael Niedermayer	c7369f3a4b	avformat/avidec: print a warning for negative sample_size Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Andreas Cadhalpun	ca234639ac	avidec: avoid infinite loop due to negative ast->sample_size If max in clean_index is set to a negative ast->sample_size, the following loop never ends: while (max < 1024) max += max; Thus set ast->sample_size to 0 if it would otherwise be negative.

Andreas Cadhalpun	0eec40b713	avidec: check for valid bit_rate range If bit_rate is negative, it can trigger an av_assert2 in av_rescale_rnd. Since av_rescale returns int64_t, but st->codec_bit_rate is int, it can also overflow into a negative value.

Michael Niedermayer	8a91ee7837	avformat/avidec: Do not call av_log() per byte, use ff_tlog() This was av_dlog() previously and should not have been changed to av_log() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	1a3eb042c7	Replace av_dlog with normal av_log at trace level This applies to every library where performance is not critical.	10 years ago

Gabor Nagy	ae8168074e	avformat/avidec: Increase dshow_block_align use threshold by 1 Fixes 00.avi Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Joakim Plate	90411b333d	Allow reading of growing avi files (currently being written) This uses the RIFF header stored size to figure out the expected AVI file size, instead of the actual file. To work fully it requires handling failed avio_seek() instead of assuming they always succeed. Some fate file has been cut off and contains half a frame at the end which previously was not output during demuxing. This frame is now output to encoder, thus the fate diff update.

Benoit Fouet	9c843fb1d0	avformat/avidec: ensure that palette does not contain the BottomUp info. Considering the palette is located at the end of extradata may be flawed when the extradata contains the palette followed by the BottomUp field. When the BottomUp field is present, exclude it from the palette. Fixes part of ticket #1304 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
