vf_scale_vaapi: Crop input surface to active region
Merged-by: Clément Bœsch <u@pkh.me>
|
| |
| |
| |
| |
| |
| | |
If the input has been decoded from a stream which uses edge cropping
then the whole surface need not be valid. This defines an input
region for the scaler so we only use the active area of the frame.

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.

to showwavespic by name
The 'sqrt' and 'cbrt' scalers were added in commit
80262d8c86e94ff9a4bb3a9e3c2d734e04ccb399, but their symbolic option values
only made available to the showwaves filter, not showwavespic, despite
the scalers working properly by their numerical option values.

When setting the channel layout directly using AVBufferSrcParameters
the channel layout was correctly set however the init function still
expected the old string format to set the number of channels (when it
hadn't already been specified).

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.

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.
