FFmpeg Idet with Timecode/Frame Number ?
13 avril 2021, par Matt CohenIs it possible to get ffmpeg to tell you which frames it thinks are interlaced/progressive when running the idet filter ?


My use case is that when interlaced frames are detected in a file I need to be able to know which frames ffmpeg thinks are interlaced so I can easily pull them up and check if ffmpeg was correct in its assessment. Sometimes aliasing and thin lines in animation throw it off.
