ffmpeg
doesn't seem to frame index at all, maybe it doesn't need to. However, if you plan to use AVC videos with
AviSynth or VapourSynth or are trying to get the best possible deinterlace, then I recommend using libavcodec
's
indexing capabilities.
For synth programs, this can be done using L-SMASH-WORKS, do NOT use FFMS2 or ANY ffmpeg based sourcer for synth programs, they are WAYYYY too outdated and I can confirm they break color in specific ways that you WONT notice (proof: https://slow.pics/c/R5sA6wli comparison between ffms2 output vs without)!!
