Precise cut of remote video file
20 août 2014, par Nicolas GoyI have hours long video files living on a server, and I need to be able to cut segments in them in an accurate and fast way.
I tried :
ffmpeg -ss 10:00 -i http://server/input.mp4 -t 5:00 -vcodec copy -acodec copy out.mp4
This works and is fast, but it’s not precise as ffmpeg seeks backward until it finds a keyframe. The resulting video file ends up with a negative start time which is not working nice with browsers.
I know I can re-encode the video for accurate seeking, but this would be slow and lose quality.
I came up with the following idea :
For example, let’s say we have a 20 seconds video, with keyframes every 5 secs, at 0,5,10,15,20.
If I want a segment from sec 2 to sec 17, I would re-encode from sec 2 to 5, vcopy from sec 5 to 15, re-encode from sec 15 to 17 and concat the three files.
This is the general problem and my idea, now the requirements are :
- Source files must be accessed over HTTP
- There must be no or very few quality loss
- It must be fast, cutting 10 minutes in a 2h video should take around 1-2 sec
- It must be accurate
- It must work for webm and mp4
It doesn’t have to be a ffmpeg command, I’m quite sure I’ll have to write a C wrapper around libav.
Source file can be pre-processed in any necessary way to make it work.
UPDATE : After getting more info, it seems my "idea" of gluing re-encoded extremities parts with a stream copied middle part won’t work because of different encoding settings. But I could extract a longuer part (keyframe -> keyframe) and extract timecodes I could add in an HTTP header, like
Time-Range: 0.25,15.14
which would mean "play from sec 0.25 to 15.14 and discard the rest".
