Description Red 2019-04-20 06:19:52 UTC
When ffmpeg is built with USE=flite, it causes the following problems with mlt and kdenlive:

1. melt query="formats" gives the error:
mlt_repository_init: failed to dlopen /usr/lib64/mlt/
  (/usr/lib64/ undefined symbol: usenglish_init)
# No formats - failed to load avformat consumer

2. kdenlive replaces the video preview with a green box and refuses to import files with "Clip is invalid, will be removed from project" error.

3. When opening a previous project, all the clips in the project are replaced with "INVALID" etc and refuse to play.

4. After using Settings->Run Config Wizard, it gives an error message that the libavformat module is missing and that it is needed to run the program.

All of this can be avoided when removing USE=flite from ffmpeg.

Newer versions of dependency libraries breaking their users are normally not caused by the dependency library - the users of those libraries need to be updated instead.

Hence, this bug report is now about media-libs/mlt - please file a separate bug report for kde-apps/kdenlive
Comment 2 Red 2019-04-20 22:36:23 UTC
The kde-apps/kdenlive issues are filed as bug 683924.

Is that still happening with mlt-6.16.0?

No longer blocks stabilisation after USE=-flite was forced.
