[MP4] Can't fast forward or rewind

[yetanotherlogin]

Hello

I searched the archives but didn't find a thread on the subject.

Using TubeMaster I saved a streaming video into a file, but when I try to view it in VLC, it plays OK but I can't either fast forward or rewind.

Would another container solve this issue? If that's the case, can ffmpeg do this?

Here's what VLC says about the file:

Video H264 MPEG4 AVC (part 10)
Audio MPEG AAC mp4a

Thank you.

You could try remux with ffmpeg,

ffmpeg -i video.mp4 -acodec copy -vcodec copy newvideo.mp4

It just copies the video and audio.

You could also try change to newvideo.mkv and make a mkv. Or use mkvtoolnix, add mp4 the and make a mkv.

Some could probably give a more complete answer, but some encoding options can negatively affect video seeking.

For more help with that particular file it's really help if you opened it with mediainfo (which every video user should have) and posting the results.

Or if possible you could see what file options tubemaster (which I don't know) has and try again.

Or ... just try another program. If I paid for a program I'll spend a lot more time and effort jiggering it than with a free program. With those my first impulse tends to be to try another one.

I usually just use the download helper firefox plugin, but my needs are simple. I don't download streams from sites that hide the actual url.

Thanks for the help.

ffmpeg -i video.mp4 -acodec copy -vcodec copy newvideo.mp4

Here's the output:

...
[flv @ 02102320] Stream discovered after head already parsed
...
[mp4 @ 02759020] Application provided invalid, non monotonically increasing dts
to muxer in stream 1: 12816 >= 11952

You could also try change to newvideo.mkv and make a mkv.

It fails the same way:

C:\>ffmpeg -i myfile.mp4 -acodec copy -vcodec copy newvideo.mkv
...
