Hello. I use youtube-dl (https://github.com/ytdl-org/youtube-dl), an open source application that utilizes ffmpeg to merge the audio and video streams that it downloads.
There apparently is an issue where ffmpeg will error out on trying to join VP9 HFR video in 720p and 1080p to Opus audio. The problem is that this doesn't happen all the time, just some of the time. In the github for youtube-dl, the issue (https://github.com/ytdl-org/youtube-dl/issues/28042) lays out the problem. On the chart of youtube itag formats here ( https://gist.github.com/AgentOak/34d47c65b1d28829bb17c24c04a0096f), it is format codes 302 and 303 that are failing to merge with itag code 251 (Opus audio). The other users in the github thread state that this is an issue with ffmpeg, and affects all versions, including Linux. This is an example of the error I experience on my Windows 10 x64 computer: Y:\youtube-dl>youtube-dl --cookies cookies.txt --download-archive "deltrons_hqv5vp9.log" -i --add-metadata --embed-thumbnail -o "deltron - Videos/%(title)s - %(id)s.%(ext)s" -f --merge-output-format --format (337/315/313/336/308/271/335/303/248/334/302/247/333/244/332/243/331/242/330/278/305/266/304/264/137/136/135/134/133/160)+(251/bestaudio) -x -k --write-description --write-info-json --cache-dir "Z:\cache" --sleep-interval 4 --max-sleep-interval 9 --verbose --fragment-retries 100 https://www.youtube.com/watch?v=MakTbhIZ5zo [debug] System config: [] [debug] User config: [] [debug] Custom config: [] [debug] Command-line args: ['--cookies', 'cookies.txt', '--download-archive', 'deltrons_hqv5vp9.log', '-i', '--add-metadata', '--embed-thumbnail', '-o', 'deltron - Videos/%(title)s - %(id)s.%(ext)s', '-f', '--merge-output-format', '--format', '(337/315/313/336/308/271/335/303/248/334/302/247/333/244/332/243/331/242/330/278/305/266/304/264/137/136/135/134/133/160)+(251/bestaudio)', '-x', '-k', '--write-description', '--write-info-json', '--cache-dir', 'Z:\\cache', '--sleep-interval', '4', '--max-sleep-interval', '9', '--verbose', '--fragment-retries', '100', 'https://www.youtube.com/watch?v=MakTbhIZ5zo'] [debug] Encodings: locale cp1252, fs mbcs, out cp437, pref cp1252 [debug] youtube-dl version 2021.04.07 [debug] Python version 3.4.4 (CPython) - Windows-10-10.0.19041 [debug] exe versions: ffmpeg 2021-02-16-git-8331eb058d-full_build-www.gyan.dev, ffprobe 2021-02-16-git-8331eb058d-full_build-www.gyan.dev [debug] Proxy map: {} [youtube] MakTbhIZ5zo: Downloading webpage [youtube] MakTbhIZ5zo: Downloading MPD manifest [info] Writing video description to: deltron - Videos\LIGHTSKINJOHN - only - MakTbhIZ5zo.description [info] Writing video description metadata as JSON to: deltron - Videos\LIGHTSKINJOHN - only - MakTbhIZ5zo.info.json [youtube] MakTbhIZ5zo: Downloading thumbnail ...

I would have wanted to submit a bug report itself, but I don't use ffmpeg directly most of the time, only through youtube-dl. There is no movement on this bug in youtube-dl and their developers don't seem to want to contact you, so I am doing it myself. I would appreciate it if we could look into this issue. Please let me know if I can provide further information. Thanks again. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
