Hi!
Is there a patch/plugin/tool/whatever which would make VDR somehow tag recordings where there were stream-error when recording?
It shouldn't be too hard to scan a *.ts-File for discontinuity errors, but I would like to make VDR detect this while recording and somehow set a flag, so I can see if a recording might have errors.
BR,
Tobias

No idea anyone?
What else besides continuity errors could be checked, to see if a TS recording has errors?

There are at least a few tools for Windows that can do that. If you have a Windows box, you may want to look into using that for this.
I'm using attached script to see if there are any errors in the video.

On the outer TS layer, you can check for TS packet structure ("skipping bytes to sync on next TS packet") and TS discontinuity, thats probably all. However this gives quite good hints on data loss and buffer overruns.
On PES layer, there's not much to check, and everything below PES layer is encoding specific and would require mpeg2 / mpeg-audio / ac3 / h264 specific scans, that are more complicated.
Also, I wouldn't be surprised if there are errors close to the beginning / ending of a recording, that you may have to ignore.
Cheers,
Udo
