I know the function definition says it returns -1 on error, but that's
already not the case: It can return AVERROR_INVALIDDATA by means of the
call to parse_config_ALS(). I believe the doc should be changed, and
this code change should also return AVERROR_INVALIDDATA.

Furthermore, can you pass and find a useful context for this av_log()
(and for the one in parse_config_ALS()? av_log() with NULL context is
very unfortunate.

Cheers,
