Bug ID: 419091
Summary: x264-nvenc too many jobs at the same time
Product: kdenlive
Version: 19.12.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Video Display & Export
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1. Add a bunch of clips, more than the amount of GPU's in the system...
2. Select all the clips
3. Make proxies
OBSERVED RESULT
The x264-nvenc proxy process is spawned for every clip selected, which is
undesirable as you can only encode one video per GPU. You will get a bunch of
errors which become very cumbersome to click away if you added a hundred clips.
x264-nvenc either complains it ran out of memory or that parameters were
incorrect for the video, but a single proxy encode always works.
EXPECTED RESULT
x264-nvenc is spawned once per GPU and the entire proxy process is batched to
keep every GPU occupied.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: KDE neon 5.18
(available in About System)
KDE Plasma Version: 5.18.3
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.1
ADDITIONAL INFORMATION
I have two GPU's in my system and seem to be able to encode two videos at the
same time. I assumed it spawned a job on each GPU, but have not tested yet.
