Avidemux Forum

I can confirm building avidemux from the updated source on both Ubuntu 2604 and Linux Mint 22.3 correctly opens and handles .ts and .m2t files. Nice work quick fix!

Any particular reason why the executable module is named avidemux3 in the build avidemux2 directory? Big changes coming needed a version upgrade?

Thanks again. This problem is closed. (and I will delete my linked files)

Correct, my first cursory assessment of the effects of that typo (and one leftover I missed back then) was incomplete.

I would very much recommend not to depend on anyone to provide binaries as building Avidemux from source on Linux is very easy (on Ubuntu 26.04, just please install qt6-base-private-dev package manually, it had been added to build requirements recently, but not yet to the convenience script createDebFromSourceUbuntu.bash).

Thank you for your report.

Yes, the files are on a system with write access, but changing Index Files to Enable did not work for me - same error. I will patiently wait for the next Nightly and will report when I test that one. Thank you for your help!

Typo of doom fixed, please build from source off the latest git master or wait for a future nightly, my apologies for the inconvenience.

Oops, if the files are located on a filesystem with write access, please switch indexing mode for MPEG-TS in the Preferences -> "Import" tab -> "Index files" to "Enable". In-memory indexing just for MPEG-TS with MPEG2 video must have got broken by demuxers/MpegTS: obey indexing preferences, remove a few redundant std::string ctors, reorder tsHeader class members for legibility. Will try to look into this regression ASAP.

Regular x86_64 and legacy x86_64 AppImages from 20260414 through the current 20260516 fail on open of recorded TV files .ts and .m2t. Regular AppImages were tested on Ubuntu 2604. Legacy AppImages were tested on Linux Mint 22.3 (Ubuntu 2404 base).

I have been recording television programs for years on my Hauppauge HVR2255 (creates .ts) and Hauppauge WinTV-quadHD (creates .m2t). AppImage 20260411 is the last to successfully open these files.

I can provide a sample 1 minute recorded TV file and a terminal log of the failure on my website, but it is 100% reproducible ... what else do you need?

Worked for me on my MacBook Air M5 16GB, Tahoe 26.5
Very simple and straightforward.
Thank you very much!!

thanks too, this was interesting to know .

Does Avidemux log these kinds of "EXCEPTION_ACCESS_VIOLATION" errors anywhere? I had a series of them before I finally figured out the culprit(s) and the fix(es), but I did not think to make a note of the details of the Error for future reference.
Any chance they got logged somewhere?

Say YES to the re-encoding. Then do a COPY SAVE (on both video and audio - no filters) of the file.
Load the newly saved file. The video frames should be corrected, but if your audio is still out of sync, use the audio Shift to move it back or ahead til sync is restored, and then COPY SAVE again.
If that does not help (with this problem or future ones), then it's probably more complicated than my experiences with keyframes and audio issues.
