Jun Zhao 0baf540461 vf_hwupload: Add missing return value check 
Add missing return value checks to suppress build warning and
remove noop ff_formats_unref() calling.

Note: most filters using ff_formats_ref() didn't have a suitable
error handling, it's a potential memory leak issue.

Nicolas George 5f344b5c1f lavfi: make ff_framequeue_skip_samples() more useful. 
Instead of just updating statistics and leaving the work to the
call site, have it actually do the work.

Also: skip the samples by updating the frame data pointers
instead of moving the samples. More efficient and avoid writing
into shared frames.

Marton Balint 7ec3250899 avfilter/formats: do not allow unknown layouts in ff_parse_channel_layout if nret is not set 
Current code returned the number of channels as channel layout in that case,
and if nret is not set then unknown layouts are typically not supported.

Also use the common parsing code. Use a temporary workaround to parse an
unknown channel layout such as '13c', after a 1 year grace period only '13C'
will work.
