postprocessing tsduck on recordings

[Druhl]

I have concluded (Martin has helped me to conclude) I have a few channel streams of less than optimal quality. They *seem* fine but produce TS files when recorded that have skipping / seeking problems (I suspect caused by time index or stream interruption issues). After having really optimized groups and EPGs etc. I don't wish to change providers unless I have to, and hope I can instead do the following:

I see people using postprocessing scripts for various things here but not for tsduck; I see people using tsduck for stream and file analysis but not seemingly postprocessing.

I was wondering about having tsduck run after a recording completes to analyze and correct errors it finds (e.g. tsfclean, tsfixcc, tsftrunc, tsresync)
and re-write the file. I wish to avoid actual "re-encoding" of a file in a way that lowers quality.

Is this something anyone here is doing, or is even possible?

You can use any utility you want in post processing, but why do you think tsduck is going to fix your issue or is any better than ffmpeg?

I know I am only basing things on one sample but to make it seekable you need alchemy and would be surprised if you have come up with any way to automate a clean up, tsduck utilities won't even open that recording as-is.

My objective would be that tsduck is hopefully able to analyze and correct timeline and other errors and just re-write the container for the file, rather than have ffmpeg re-encode the bitstream.

In any case, I don't want to reinvent the wheel; this looks like a lot of bother. I'm going to try a couple other providers and see if the problem just goes away.

I think you over estimate tsduck and under estimate ffmpeg. Your recording needs much more than a simple remux.
