I’ve searched and found many examples of people having the same issue and it finally happend to me as well. I checked the problematic file and it turns out that FFmpeg can’t handle the file correctly: [h264 @ 00000171edc519c0] mmco: unref short failure [h264 @ 00000171edc52740] illegal short term b…

I don’t think bidir is better than nokey for this issue. It’s been a while but I’m 95% sure I tested that too. Are you having this issue? Does your media match the discussion above? Share a sample if you like.

I have noticed this happening more often in the last month or two as well. Pretty convinced I have wonked files, but it didn’t happen before.

yeah, i have the same error message on my file. [h264 @ 000002071c3f9a40] illegal short term buffer state detectedup=45 drop=0 speed= 117x [h264 @ 000002071c375340] mmco: unref short failure bitrate=N/A dup=45 drop=0 speed=1.22x [h264 @ 000002071c375340] illegal short term buffer state detected [h2…

Sure, I will. I wonder if it’s a similar-but-different issue, or if I’m mis-remembering about testing bidir before. The issue in the files we were looking at was poor identification of keyframes when nokey was used. In some cases I frames were almost all skipped, leaving nothing to make previews wi…

You can find a test sample in this thread . Anyway, I remember testing with bidir and yeah, it works, although it can/will generate duplicates. The preferred solution is still default for those problematic videos, but maybe bidir would be a better default than nokey (because it’s still fast and does…

[image] Ari: it works, although it can/will generate duplicates bidir shouldn’t be worse than nokey in that regard, and it ought to be better. That’s part of why I’m comfortable recommending an increased GenerateBIFFrameInterval value. Making duplicate preview frames because of dropped sourc…

[image] Volts: @Mitzsch what’s the origin story/provenance of your file? The file is from a bluray that I purchased a while back. (Score - Eine Geschichte der Filmmusik) MediaInfo: Video ID : 1 ID in the original source medium : 4113 (0x1011) Fo…

Another file (Lady Vengeance - remastered bluray) with almost the same behavior. (no mmco: unref short failure bitrate error message) [h264 @ 0000027d8d30ad80] illegal short term buffer state detectedup=23 drop=0 speed=1.97x [h264 @ 0000027d8d30ad80] illegal short term buffer state detectedup=23 dr…
