Omitting the bitrate, using CRF only (without -b), using VP8, or invoking vpxenc manually all work.

Is the problem reproducible with -an
?
Does -f lavfi -i testsrc
allow to reproduce?
Please test current git head.

Replying to cehoyos:
Is the problem reproducible with
-an
?
Yes.
Does
-f lavfi -i testsrc
allow to reproduce?
[lavfi @ 0xd1b820] No such filter: '4ls.mkv'
4ls.mkv: Invalid argument
Please test current git head.
Compiling.
Of note, the issue may not be -b:v itself, but passing a sufficiently high -b:v. -b:v 200k does not appear to exhibit the problem, but -b:v 1M does. Is there any way to extract a vpxenc command that I could run manually to test this?
When I ran vpxenc, I passed --target-bitrate=1000, but I have no idea what any of the more internal options do, so I omitted them.

Wait, no, there's still some improper encoding. In the last few seconds, the fadeout has chunks lingering at too-high brightness.

Actually, that may have been due to my video setup. I can't reproduce it anymore.
How do I close this?
