Spectacle hanging at fullscreen recording
SUMMARY
Recording with Spectacle fails with
[AVFormatContext @ 0x7f1560956800] Unable to choose an output format for '';
use a standard extension for the filename or specify the format manually.
kpipewire_record_logging: Could not deduce output format from file: using WebM.
""
kpipewire_record_logging: Could not open "" No such file or directory
STEPS TO REPRODUCE
See attached video:
1. Start recording VP9 in fullscreen
2. Recording fails and application hangs
3. Restart application
4. Recording rectangular area first: recording works
5. Recording fullscreen after rectangular: fullscreen works too now
5. Changing recording format to h.264
6. Restart application and try to record fullscreen. Fails as with VP9, but
interestingly output still mentions WebM
In conclusion:
- Starting with a fullscreen recording fails with aforementioned error message
and spectacle hanging.
- Recording a rectangle area first and fullscreen afterwards works with VP9 and
h.264
