Uses a similar approach as vf_yadif to flush the last frame in idet. Quick test with 50 frames from vsynth1: ./ffmpeg.old -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 | grep Multi (gives) [Parsed_idet_0 @ 0x261ebb0] Multi frame detection: TFF:0 BFF:0 Progressive:48 Undetermined:1 ./ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1 | grep Multi (gives) [Parsed_idet_0 @ 0x35a0bb0] Multi frame detection: TFF:0 BFF:0 Progressive:49 Undetermined:1 Fate tests have been updated. (In testing, it seems this filter will also need a subsequent patch for single frame input) Signed-off-by: Neil Birkbeck <neil.birkbeck@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
