--- Comment #9 from Chris Gebhardt <d...@openserve.org> --- I got my local build working and pulled your latest changes on 'Applications/16.04'. Behavior is still inconsistent. On a fresh project, some clips will get thumbnails. On existing projects, I can sometimes get thumbnails to generate when switching project profiles. It does seems as though "Use FFMPEG for audio thumbnails" is a problem, even though FFMPEG is installed. (2.7.6-0ubuntu0.15.10.1) When this option is selected, I will sometimes get audio fingerprints, although the waveform amplitude is extremely low, and often it only works on audio files. With the FFMPEG option deselected, I can get proper waveforms on all clips, but sometimes only after switching profiles to force regeneration. Also, are thumbnails cached anywhere besides $HOME/.cache/kdenlive-thumbs.kcache? Deleting this seems to have no effect in any case. Sidenote: After changing the project profile, I'm also very consistently getting crashes during many operations, including attempting to save the project or adding a new clip to the timeline. -- You are receiving this mail because: You are watching all bug changes.
