Hi, I want to sequentially parse a set of input videos and output all their keyframes in monotonic unbroken order... so videos a,b,c,d with 10 frames each should produce 0-50.jpg If thye videos where concatable and the concat process lossless I could do ffmpeg -f concat -i vids.txt concat.vid and then ffmpeg vsync -skip_frame nokey -i concat.vid %06d.jpg But they arent, and it isnt... tips?
