I can modify the script to extract the parts I need, that's not the problem, but I don't know how to modify the timestamps. The timestamps of the first part are fixed correctly, but the start time of the second part does not 'connect' to the end time of the first part.

If the first part is one minute long, then the timestamp of the last video frame is 1:00.724, this is correct, but the timestamp of the first video frame of the second part starts with 5:37.141.

I don't know if there's a fairly easy fix for that or if a large part of the script needs to be rewritten, which is not worth it.

without actually trying to make it do so i can't say for sure but it may be a bit tricky. $baseTS value should be updated with new starting timestamp for correct rebasing.

Re: FLV fixer script

Trimming Video! For example, I give it a duration or imputing a value that trim from a time to another time! like start and stop of rtmpdump!

Re: FLV fixer script

KSV is there any way you can modify the script to fix the videos from MyFreeCams.com, Naked.com and Cams.com?

These websites deliberately put a random wrong timestamp in the video after 2/10th of a second, so most video players are not able to play the recorded videos properly. VLC can play them, but most other video players play only those first 2/10th of a second.

The only frames with the correct timestamp are the keyframes.

Re: FLV fixer script

I could be wrong but it appears you can fix this by simply remuxing with FFmpeg

Code:
$ ffmpeg -i sample.flv -c copy a.flv
