"ExceptionFilter" while opening a mpg-File

[DerAndereMicha]

Hi,

I have been using Avidemux for a long time and have never had any problems. But now I have a problem while opening an mpg-file (error message attached). I hope somebody can help me.

Updating to the latest version didn't help either.

Best regards

The latest build is from 2019-09-24: https://avidemux.org/nightly/win64/
Did you try it (just to be sure)?

Please rename the corresponding *.idx2 file, let Avidemux re-index the video. If the problem persists, please compress (7z, zip) the new *.idx2 file as well as the corresponding admlog.txt from %localappdata%\avidemux and attach them to your reply.

It may be necessary to have a look at the .mpg video itself later in the process.

[DerAndereMicha]

Yes, I have used the latest build.

I could only attach the log, the packed idx2 file is too large (8 MB). The corresponding MPG file has a size of 20 GB (a record from a whole night). However, the large size has never caused any problems.

Best regards

Would you please upload the compressed *.idx2 file to a service like WeTransfer, Mega, Dropbox or Google Drive?

The size and the duration of the source video is really huge, maybe we do hit some internal limits.

[eumagga0x2a]

Thank you for the log and the index file, will try to look into the latter soon.

If you have a text editor capable to handle files that large and able to preserve unix-style line endings (LF instead of CR+LF), you could copy the end of the index

[End]

to a different file, delete e.g. the half of the index (always pairwise the lines starting with "Audio:" and "Video:"), then append the end of the index and see whether the problem is located in the second half of the index.

[eumagga0x2a]

We crash reading the entry 6476 from the index. As suspected, the max line length of 2000 chars allocated is too small, this happens at line 12961 of the index.

[DerAndereMicha]

If I delete the first 15,000 lines, it'll work. I can work with it for now.

Thank you very much for the quick help!

Fix upcoming.

[eumagga0x2a]

Should be fixed by [demuxers/MpegPS] Increase max video index entry length, fix NULL pointer dereference from a truncated entry, please try a future nightly.

Thank you for your report.

Fresh nighly builds have been uploaded, please try a 191003 one --> https://avidemux.org/nightly/win64/

[DerAndereMicha]

Yeah, it's working. But now there is a new problem. Saving doesn't work anymore (already with the last nighly build).

The following message appears:

[eumagga0x2a]

More info, please (admlog.txt).

This looks like the destination were a network drive. I'm not sure this is supported by Avidemux (the only protocol enabled in the internal libavformat is the file protocol). Please retest with a local output target.

[DerAndereMicha]

Right, that's a NAS. But it still worked with version 2.73. Local saving also works with the latest nighly build.

It would be a pity if functionalities that once worked were removed.
