Wallset video feature MP4 compression issues
vsawce opened this issue · comments
The video feature compresses the MP4 file rather than displaying the source quality. The video tested is a simple 7 second, 1920*1080, 9MB MP4 video.
It was set using wallset --video [directory] using both regular and superuser privileges.

Issue occurs on Linux Mint 19.3 Cinnamon.
CPU: Ryzen 2700x
GPU: GTX 1060 3GB
Memory: 16GB 2933MHz
A workaround is to adjust the ffmpeg arguments under the _video function.
Adding "-qscale:v [2-31, 2 = better quality and 31 = worst quality]" before "-t 10" should fix poor compression issues. Note that in able for this workaround to work, you must uninstall and reinstall wallset using "sudo ./install.sh uninstall" and then preferably restart your computer.
However, this workaround seems to slow the frame-rate somewhat, even after minimizing/deleting the sleep statement under the feh loop. The issue seems to stem from a limit of feh's speed.
I commented out the convert and feh lines and reduced sleep to 0.005
