Hi,it seems that versions 7.1 and 8.0 of ffmpeg introduce a regression in the select filter. Indeed, in order to extract images from a video at specific times, I use the following command: ffmpeg -y -nostdin -ss 1 -i video.mov -vf "select='eq(pict_type\,I)+eq(pict_type\,P)'" -pix_fmt yuvj420p -an -frames:v 1 -q:v 3 -update 1 thumbs_0001.jpg This works well for MP4/H264 videos, but for MOV/ProRes videos (when the file is larger than 50GB) the command only works in version 7.0 and runs forever on version 7.1 or 8.0 Using ffprobe, I confirm that all the frames are of type pict_type=I ? So I could suppress the filter for MOV videos but then I will have multiple commands depending on the kind of videos.
Can you open an issue about that? https://code.ffmpeg.org/FFmpeg/FFmpeg/issues
