Problems with quicktime reference clips

[bastibeckr]

Summary of the bug:
Hi, i have tried to convert a quicktime reference clip that links to 2 original files. The clip is made with final cut 7, ​test-clip. Let me know if you also need the original footage, it's simply some prores footage, but the codec doesn't matter.
How to reproduce:
If the sequence in final cut does not contain a "cut", everything is ok. So i can export a part of a single file, export it as qt reference and encode it with ffmpeg.
But if I add a second clip or even the same clip twice, export the sequence as reference, it will output an error. This only happens with reference clips. The clips are viewable with quicktime player or MPEG Streamclip.
I tried this with "-use_absolute_path 1" and without, always the same error.
Any help is appreciated. Thank you.

test_two.mov is missing afaict, and if possible, it would be nice if you could provide a sample with relative paths. Or is that impossible with fc?
Please test current git head.

Generally, please do not cut FFmpeg output but provide complete, uncut output, do not use external libraries if it is not necessary to reproduce the problem and it is appreciated if your command line matches the sample that you provide.

Hi, thanks for your fast response.

I will find out if I can create a clip that contains references to relative paths.

test_two.mov is reported by ffmpeg to be missing. But with other players I can play the clip - it fails in ffmpeg.

if I create a sequence that contains only test_two.mov or one part of it, it will work.

e.g. my sequence looks like:

[test_two.mov] => works
[test_two.mov|test_two.mov] => doesn't work
[test_two.mov|test_one.mov] => doesn't work

(the source clips may be truncated, but the result must only consist of one clip (no cuts)):

[first-part-of-test_two.mov]  => works
[first-part-of-test_two.mov|second-part-of-test_two.mov] => won't work

There are no gaps between the cuts, it's comparable to a "playlist". Again, will seems to be valid quicktime because other players don't complain and play the file without any problem.

thanks again, i will try to match your requirements (no ext. libraries, etc) and provide feedback with full output when i'm done.
