Jun Zhao	bf238a6a3c	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.

Mark Thompson	e3fb74f7f9	lavfi: Always propagate hw_frames_ctx through links Also adds a new flag to mark filters which are aware of hwframes and will perform this task themselves, and marks all appropriate filters with this flag. This is required to allow software-mapped hardware frames to work, because we need to have the frames context available for any later mapping operation in the filter graph. The output from the filter graph should only propagate further to an encoder if the hardware format actually matches the visible format (mapped frames are valid here and have an hw_frames_ctx, but this should not be given to the encoder as its hardware context).	9 years ago
