Can not import movies

[magdesign]

when importing a movie, I always get following error and it crashes:

the "deprecated pixel format used, make sure you did set range correctly" can be ignored

"Lavf mjpeg" mmmm.... I think this means your trying to import a mjpeg clip? not tried that before. Ideally, I'd like to get my hands on the actual file you are trying to import to be sure, but if not, can you confirm the codec 'eg. via VLC > tools > video codec information' or however you would normally do it. In the mean time I'll see if I can reproduce. Cheers.

had success downloading and importing some mjpegs here. Looking again at the error, it looks like its more to do with ffmpeg then anything I'm doing.

I could do with a file like this, so I can improve recovery from the ffmpeg crash, any chance you could point me at an offending file? could send a link to vidifold@gmail. cheers.

sorry for the late replay, was busy producing our exhibition (with using vidifold!), the workaround I used was converting the movie to matroska format and then importing worked.

Here a file which is causing vidifold to crash on import: https://www.swisstransfer.com/d/9df801e2-a491-4aed-86e4-5df08f56e092 The file is made with DaVinci Resolve, AVC CABAC MPEG-4, they say its a h264 mp4, on Linux.

Hi, cool, hope it all works out. Big thank you for the file. Unfortunately, it just loaded in with no problems here. Must be some difference in the ffmpeg versions :( I haven't done anything special with mine, just went with what was default.

ffmpeg -version

do you want to post yours here, or shall we close this ticket for now?

I've just twigged that the metadata you sent over is from the frame extraction, which does indeed map h264 > mjpeg. This was the source of my confusion with the file type. Anyway, no idea yet why it fails for you.

My ffmpeg version:

ffmpeg version 4.2.4-1ubuntu0.1 Copyright (c) 2000-2020 the FFmpeg developers
  built with gcc 9 (Ubuntu 9.3.0-10ubuntu2)

I have one proprietary mpeg video codec (RVA) installed, maybe this is causing the issue...

thanks for looking into it!

[magdesign]

I will close this issue since I can not figure out if its an issue on vidifold, ffmpeg or the RVA codec.

If someone else have the same trouble, please re-open.

Hi again, apologies, but I think I've twigged the problem.

It was me, I didn't see the error at all as it was a new check I'd forgotten I'd added recently after seeing a blank 'Bank' label (which could cause a lot of problems). I'm not 100% sure why, but I suspect it's to do with character encodings in the file path. I've put a 'Default' option rather than this exception.

Funnily enough, I've just been researching encoding problems in C++, and it's starting to look like a nightmare, it seems that a lot of the basic string functions are not safe! Silly me thinking that string manipulation would be simple and robust by now.

I mostly use PHP at work where this is so much easier.

Anyway,

New version uploaded to site, v0.31.10, hopefully that should help.

[magdesign]

Great, I will test with the new version and report...
