[FFmpeg-devel] [PATCH 3/4] ffmpeg: with filter_complex, avoid random in<->out mapping.

[Nicolas George]

Le septidi 17 prairial, an CCXX, Michael Niedermayer a écrit :
> ffmpeg -i matrixbench_mpeg2.mpg -filter_complex null test.avi

Indeed, and that is to be expected. OTOH, the current behaviour, or the one
you suggested, break, differently, on something like that:

ffmpeg -i matrixbench_mpeg2.mpg -filter_complex 'setpts=2*PTS' test.avi

Using -filter_complex is, inherently, complex. The code I propose to remove
only works in the simplest of cases. In fact, mostly in the cases where
complex filters are useless.
