Logging can't be disabled

Created by: pohmelie

Overview

I want to shut up any logging from av and underlying ffmpeg. I tried all of this:

logging.basicConfig()
av.logging.set_level(av.logging.PANIC)
logging.getLogger('libav').setLevel(logging.ERROR)

Btw, docs said there is av.logging.QUIET, but it missed.

Expected behavior

No logs.

Actual behavior

I encode video frame by frame. I see tons of almost equal output like this:

[jpeg2000 @ 0x7f8408000940] End mismatch 3
[jpeg2000 @ 0x7f8408000940] End mismatch 4
[jpeg2000 @ 0x7f8408000940] End mismatch 4
[jpeg2000 @ 0x7f8408000940] End mismatch 3
[jpeg2000 @ 0x7f8408000940] End mismatch 3
[jpeg2000 @ 0x7f8408000940] End mismatch 3
