Hi :) been using the forum for a few years but my time with a question has come, so I only registered now. Sorry for that guys;)
That said my problem is: I have a captured FLV from a streaming website and when I have the completed file the timeline shows something like 6 days, 23h, etc when it actually has 5 or 6h. I can solve that by using FLVextract and then join the files together with mkvmerge.
After this the video and audio length are okay but the audio is coming early so I had to go into mp3directcut to had 9.25s to the audio file and join them together again.
Things were going fine until almost the end of the video. This is when I face the following: video goes normally and audio too, a still picture shows up (part of the captured stream, all fine here including length) and then the audio delay has to be shifted to 7.8s so everything matches.
As the video (avc1) has keyframes I can't really cut and paste the video to add the extra 1.5s to the still image. The ideal is to at the precise point things doesn't match anymore I could shift the audio. A problem surfaces, the audio gap between part1 and part2, and that's when I tried to copy audio from part1 to part2 but everything gets messy and I still have delay.
The goal here is to not re-encode the video/audio or at least not the video.
Here is my file info:

Any help? I used avidemux/virtualdub/video to video/mp3directcut/yamb all with direct stream copy to not re-encode the video/audio
