Hello, could anyone please help me with merging parts of a HD (HEVC) recording from a DVB-T2 set top box (001.ts, 001.dvr, 002.ts, ..., info3.dvr)? After merging in TSDoctor the video is corrupted on the divide between each two consecutive parts. Played in the set top box the video looks alright. The log:

Hello,
for this (ALi-) type of recording, you should simply open the info3.dvr file in TS-Doctor. It will automatically detect the existing parts, and drop the duplicated frames (or better: packets) at the end & beginning of the recording's segments.

Just my experience...

JiBen

That's what I did. Did you try it with a HEVC stream? With MPEG (SD) it works fine.

In fact, I did it on your own recording...
Here's the log file, with no errors detected through a check run:

PS:
Ah, I see: You actually ran the files through Tools -> File Merger, probably. There, I get the same errors.
I opened the info3.dvr file directly in TS-Doctor's main page, and created a new .ts file. That new file is also error-free like the previous check-run when opened again in TS-Doctor.

Perhaps that additional tool isn't "DVB-T2 aware"...

BTW:
Which version of The Doctor do you use?

JiBen

Yes! You're right, I merged them first. I'm using TSD 3.0.8. Now it works when I do it directly. However, I'm convinced that I tried it directly a few days ago in the same version of TSD, and it didn't work :) But meanwhile I have installed a new version of LAV Filters. May it be the reason that I had some weird version of LAV Filters installed before? Anyway, thanks a lot and I'm sorry that I didn't try it again directly (without merging first) before I posted my question.

tsduser

Glad to read that it works for you now, too.

But your question cannot be answered by me, sorry. Perhaps Cypheros could shed some light...

I, personally, doubt that the file's content will be pressed through the filters during a check, but, well, see above.

Cypheros

The file merger is a simple copy tool to merge files. Ali DVRs are needing a special treatment but that only works if all files belonging to the recording are in there. TS-Doctor can then detect the Ali format and fix the shift from one file to the next. The TS File Merger is missing this feature.

LAV Filters are not needed to process the files, only for the preview in the cutting windows or the video analysis.
