[libav-devel] [PATCH 7/9] vf_hwmap: Add device derivation

Also refactor a little and improve error messages to make failure cases easier to understand. --- Removed the useless device reference. Example use: ./avconv -y -init_hw_device vaapi -hwaccel vaapi -hwaccel_output_format vaapi -i in.mp4 -an -vf

[libav-devel] [PATCH 6/9] hwcontext: Improve allocation in derived contexts

Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves. --- Added APIchanges + version bump.

[libav-devel] [PATCH 8/9] vf_hwmap: Add reverse mapping for hardware frames

This is something of a hack. It allocates a new hwframe context for the target format, then maps it back to the source link and overwrites the input link hw_frames_ctx so that the previous filter will receive the frames we want from ff_get_video_buffer(). It may fail if the previous filter

[libav-devel] [PATCH 9/9] avconv_dxva2: Allow output of hardware frames

--- Kindof hacky, but a simple way to make hardware transcode with dxva2 work in avconv without needing the hw_device_ctx support to convert it to the hw-generic tooling. Slightly unfortunate that the pixfmt is called "dxva_vld", though. Example: ./avconv.exe -y -init_hw_device dxva2 -hwaccel

[libav-devel] [PATCH 3/9] hwcontext: Add frame context mapping for nontrivial contexts

Some frames contexts are not usable without additional format-specific state in hwctx. This change adds new functions frames_derive_from and frames_derive_to to initialise this state appropriately when deriving a frames context which will require it to be set. --- map_frames_to/from renamed to

[libav-devel] [PATCH 1/9] avconv: Support setting the hardware device to use when filtering

This only supports one device globally, but more can be used by passing them with input streams in hw_frames_ctx or by deriving new devices inside a filter graph with hwmap. --- Added doc. avtools/avconv.h| 1 + avtools/avconv_filter.c | 10 -- avtools/avconv_opt.c| 21

[libav-devel] [PATCH 5/9] hwcontext_qsv: Implement mapping frames to the child device type

--- Now uses frame context derivation, so should properly support DXVA2 (previously it didn't look like a fixed-size pool, but that didn't actually matter for some use-cases). It feels like the MemId stuff should be done more consistently, but actually every use is slightly different so the
