12 ffmpeg xfade transitions : "option not found"
17 juillet 2023, par nimdaI'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :


- 

- hlwind
- hrwind
- vuwind
- vdwind
- coverleft
- coverright
- coverup
- coverdown
- revealleft
- revealright
- revealup
- revealdown


























I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :

Sporadic "Error parsing Cues... Operation not permitted" errors when trying to generate a DASH manifest
22 novembre 2023, par kshetlineI have already-generated .webm audio and video files (1 audio, 3 video resolutions for each video I want to stream). The video has been generated not (directly) by ffmpeg, but HandbrakeCLI 1.7.0, with V9 encoding. The audio (which has never caused an error) is generated by ffmpeg using libvorbis.


Most of the time ffmpeg (version 6.1) creates a manifest without any problem. Sporadically, however, "Error parsing Cues" comes up (frequently with the latest videos I've been trying to process) and I can't create a manifest. Since this is happening during an automated process to process many videos for streaming, the audio and video sources are being created exactly the same way whether ffmpeg succeeds or fails in generating a manifest, making this all the more confusing.


The video files ffmpeg chokes on play perfectly well using VLC, and mediainfo doesn't show any problems with these files.


Here's the way I've been (sometimes successfully, sometimes not) generating a manifest, with extra logging added :


ffmpeg -v 9 -loglevel 99 \
 -f webm_dash_manifest -i '.\Sample Video.v480.webm' \
 -f webm_dash_manifest -i '.\Sample Video.v720.webm' \
 -f webm_dash_manifest -i '.\Sample Video.v1080.webm' \
 -f webm_dash_manifest -i '.\Sample Video.audio.webm' \
 -c copy -map 0 -map 1 -map 2 -map 3 \
 -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1,2 id=1,streams=3" \
 '.\Sample Video.mpd'



Here's the result when it fails :

I don't know if I need different command line options, or whether this might be an ffmpeg or Handbrake bug. It has taken many, many hours to generate these video files (VP9 is painfully slow to encode), so I hate to do a lot of this over again, especially doing it again encoding the video with ffmpeg instead of Handbrake, as Handbrake is (oddly enough, considering it uses ffmpeg under the hood) noticeably faster.


I have no idea what these "Cues" are that ffmpeg wants and can't parse, or how I would change them.
