I tried to add a watermark on a testing video to test video studio, and ffmpeg crashed every single time.
Available formats of the video on the server:
- Original file (16:9 1080p MP4)
- HLS (transcoded successfully by the server):
- 1080p
- 720p
- 480p
- audio-only
Information about watermark file:
1920x1080p PNG with transparency (created with GIMP)
Tested on PeerTube docker images: v7.1.0-bookworm and v6.3.3-bookworm. No remote transcoders were used.
This error causes videos to be forever stuck in [Privacy] - to edit state, so Public - to edit, Private - to edit, Unlisted - to edit etc. Video can be viewed as if nothing has changed, because nothing has changed. But there is a banner warning about video is being edited.
Also the Studio option is not available in the three-dots menu of that video since video supposedly being already edited at the moment.
