Bug 423028

SUMMARY

Sometimes, when many videos are imported at the same time, or a new folder is set to be proxied, proxy clips failed to be create because of running out of memory.

I am using x264-nvenc encoding profile for the proxy clips.

STEPS TO REPRODUCE
1. Choose x264-nvenc as encoding profile in Settings -> Proxy clips -> Encoding profile
2. Put a few videos in a folder and then right click -> Proxy folder

OBSERVED RESULT

Two or three proxy clips start to be generated. Next one failed with the error: "[h264_nvenc @ 0x563c15416d80] OpenEncodeSessionEx failed: out of memory (10)"

When first clips are done, it doesn't try to generate the ones that failed.


EXPECTED RESULT

It would be nice if Kdenlive could know when not to start a new proxy clip because of low memory (or handle the out of memory error better, and try again when other clips are finished). Or if this is not possible, at least an option to limit the amount of simultaneous proxy clips. That also would work nice.
