Hi there,

I have imported an *.mp4 File (downloaded by MediathekView from the German TV)

It plays fine, but Fast Forward doesn't work in the Media Player.

 

Set Top Box.: vu+ duo 4K SE

 

Any ideas why that might be?

Any chance of a fix?

Best regards,

Dave

In my opinion seeking is problematic for files that are not ts. If i remember correct a requirement for succesful seeking is order of the frames and/or frame index file present. Otherwise seeking will not work.
Seeking currently work very poorly even for recorded files from streams that are 4097 type. Since it records .stream files and meadia player process them in different way (probably throught gstreamer).
Renaming the files to ts fix that issues but that to work the file codec should be mpeg2, mpeg4, hevc...

Seeking uses MPEG I-frames, the more it is compressed, the less I-frames there are. Jumping using the number keys usually works better, but not always.

Any suggestion how I could recode it to fix this issue?
e.g. LosslessCut, Handbrake, FFmpeg et al...

Did you try the numerical keys to jump into the file?

3,6,9 with go forward and 1,4,7 will go backward.

Yes, that was helpful.

Thanks.
I'd still be interested in finding a suitable "Swiss Army Knife" utility to analyse & recode.

I use TSmuxerGui to first remux .mp4 files to .ts files. It's a fast process, it does not re-encode the file.

 

After copiing to the box I select the imported .ts file, press [menu] and select [Reconstruct AP/SC].

This will create the needed index file.
