Why not use a video native tool like ffmpeg ? I'm unclear on what the advantage of dd is here.
You could seek to second, keyframe, etc, and it would continue to work for formats that don't have fixed frame sizes.
It's true that it is quite a lifehack if you often seek to frame in raw though.
- dfox 4y agoThe advantage of dd in this case is that dd is designed for exactly this use case of having a file (or character device, ie. magnetic tape) with some kind of fixed-size records.
- verall 4y agoBecause it's bespoke raw video, ffmpeg wouldn't know what to do with it. Sure if I'm chopping up an MP4 then dd isn't going to 'cut' it ;P
