Support for it was apparently never in the codebase, and the enum values were recently removed from the public headers [1] Fixes build with latest libaom build. [1] https://aomedia.googlesource.com/aom/+/2e3cd5c5c30fa02134681cda900c32486807af3f Signed-off-by: James Almer <[email protected]>

Allows to manage the AV_LOG_PRINT_LEVEL flag as a prefix to the loglevel option value, similar to the existing AV_LOG_SKIP_REPEATE flag.

This is the only code I found within FFmpeg that still inherently requires AV_PIX_FMT_FLAG_PSEUDOPAL. It's easily changed not to require it. Preparation for the next patch.
This reverts commit 858db4b.

…ion parameter
If memory allocation fails, ERROR(ENOMEM) '-12' will be returned.
When resample() is done first, the negative size param would cause buffer-overflow and SEGV in swri_rematrix().
When swri_rematrix() is run first, resample() would not cause an error but Err num as a wrong parameter passing.
Err num should be returned immediately. And remove an unneeded term from an assert.
