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

Martin Storsjö	d872fb0f7f	lavf: Reset the entry count and allocation size variables on av_reallocp failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Nigel Touati-Evans	ef8cc06d6e	avformat/avidec: Fix incorrect detection of badly interleaved avi The method guess_ni_flag needs to divide timestamps in the index by sample_size if it is set in order to compare different streams correctly.

Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Michael Niedermayer	82d79289db	avformat: Allocate duration_error separately This significantly reduces the memory needed per AVStream when the array is not needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
