Description Laptander 2015-07-26 18:01:25 UTC
It is not possible to edit audio clip in external default audio editor application if that music file contains image inside itself.

Reproducible: Always

Steps to Reproduce:
1. Click in top menu Project -> Add clip 
2. Choose audio file, that contains an image in it
3. Right click in project tree on that file
4. Try to click "Edit clip"

Actual Results:  
You cannot edit clip, due to that menu entry is gray.

Expected Results:  
Default application editor (for example, audacity) should open with that audiofile imported.

kdenlive version 15.04.3
Using KDE Frameworks 5.12.0
Default application path is set correctly.
If you try the same, but with audio file that has not got image inside, than edit clip function is working correctly (audacity is opening with audio file opened).

Comment 3 Jean-Baptiste Mardelle 2015-07-26 19:02:23 UTC
Thanks for the report. These music files are detected as video files because FFmpeg finds a PNG stream inside, so Kdenlive thinks it is a video. I have to find a way to work around this..

And by the way, that image is not dislayed when playing on timeline. It just displays white rectangle. Probably, I should create another bug for this.
Comment 5 Jean-Baptiste Mardelle 2015-07-26 22:44:44 UTC
Fixed in 15.08 branch. 
The image is not displayed because MLT does not support this:
# melt clip.mp3 
only shows audio, no video. You can file a bug report on MLT, however I guess there are more important issues to handle in MLT.

Confirmed fixed in recent git.

The provided audio with image can now be edited and it loads in Audacity.

It seems it would be ok to close this ticket.
