Michael Niedermayer	d3d9a00bcd	ffmpeg: Use filter graph output frame rate also for frame duration estimation Previously the duration was sometimes wrong, this addition limits the value and improves which frames are choosen when reducing the frame rate Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	7b32856011	ffmpeg: Maintain higher precision pts between video filter and fps code This is a bit ugly as it attempts to keep most of the computation in integers before the double based fps code. The use of integers is to reduce the chances of rounding differences between platforms Previously the timestamp was rounded to the encoder timebase before being converted back to double precision which could cause loss of precision Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Michael Niedermayer	242f1152bf	ffmpeg: drop usage of coded_frame It causes all kinds of problems and there is no code in the muxers that reads this field Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Christophe Gisquet	4c592c3908	ffmpeg: take bsf arguments from the command line The format is now: -bsf:X filter1[=opt1=str1/opt2=str2],filter2 ie the parameters are appended after the filter name using '='. As ',' has been reserved already for the list of filters, '/' is just an example of token separation for now, but that could become part of the API to avoid each bsf using its own tokenization. The proper solution would be using AVOption, but this is overkill for now. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Christophe Gisquet	33fefdb449	ffmpeg: fix streamcopy with side data The issue is that, when the main packet data buffer is changed, streamcopy uses a temporary new packet to store that buffer, frees the old packet, and replace it with the new packet. However, in doing so, it forgets about the side data, which gets freed, but is still needed and referenced. Then, when the packet gets freed again in the normal code path, it attempts to free its side data which has already been freed. Therefore, simply avoid the first free on side data by removing that side data from the packet. Fixes ticket #3773. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
