[FFmpeg-devel] [PATCH v2] avcodec/videotoolbox: add AV1 hardware acceleration

From: Jan Ekström Use AV1DecContext's current_obu to access the original OBUs, and feed them to videotoolbox, rather than the bare slice data passed via decode_slice. This requires a small addition to AV1DecContext, for keeping track of the current range of OBUs that belong to the current frame.

Passing Objective-C flags from configure to the Makefiles was broken, as configure incorrectly used the OBJCCFLAGS instead of OBJCFLAGS variable which was then later overwritten in the common.mak: OBJCCFLAGS = $(CPPFLAGS) $(CFLAGS) $(OBJCFLAGS) The fix for this is simple, analogous to how it i

Mixing declarations and code is quite common in Objective-C (as can be seen by the number of warnings we have for this in Objective-C files) and forcing to not do it usually results in worse code, with unnecessary widely scoped variables, which in turn makes variable shadowing and accidentally usin

[FFmpeg-devel] [PATCH 06/10] lavfi/buffersink: allow av_buffersink_set_frame_size() to be called earlier

The function currently writes directly into the input link, which requires it to be called after the filter has been linked. However, the documentation does not mention this restriction and the natural place to call av_buffersink_set_frame_size() during the options-setting stage, that is before fil

This function creates AND initializes a filter, so setting any filter options after it is wrong. It happens to work when the filter's init function does not touch the options in question, but is forbidden by the API and is not guaranteed to remain functional. Instead, use avfilter_graph_alloc_filt
