Black Hole
May contain traces of nut
Anybody know how to deal with this? It's in a youtube-dl download from iPlayer. Splash and VLC only play the AAC audio. VRD complains it can't find a video stream.
Rick Stein's Long Weekends, but the episode in question is no longer available.Where from, exactly?
What does ffprobe make of it?

Not really, I don't understand what it's telling me.Does this help?
many of the available streams use the new avc3 codec, which only Windows 10 can play, so if you use Windows 7 you will instead prefer to have a file containing a stream which has the avc1 codec
ffmpeg -i input.mp4 output.mp4
(just guessing) which appears to be asking for a simple copy but seems to have started a process to output avc1 (rather than avc3). It's going to take a few hours...G:\Downloads\youtube-dl>ffmpeg -i "Rick Stein's Long Weekends - Vienna.mp4" vienna.mp4

It does! And it completed at about 30x real time (run in parallel with the existing conversion).I don't know if this will be enough to make it playable
youtube-dl --list-formats
either, all I used was youtube-dl -F
– is that a synonym?youtube-dl -f 30 <url>
(for example), and the friend has a big telly and good eyes so HiDef is worth it, so I defaulted to just taking the unfiltered (best) download (I don't remember whether I had to remux it to MP4 - I might have done).Really? It told you how to change the tag. I didn't think it was a difficult post to read and then apply to your own circumstances.Not really, I don't understand what it's telling me.
