* lavc: Rename hwaccel.h to hwconfig.hMark Thompson2020-04-261-1/+1
| | | | | This already applied to decoders as well as hwaccels, and adding encoder support was going to make the name even more inaccurate.
* pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov2020-04-101-22/+7
| | | | | | | | | | | | | | | | init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).
* lavc: replace AVCodecInternal.allocate_progress with an internal capAnton Khirnov2020-04-101-3/+2
| | | | This is a constant codec property, so a capability flag is more appropriate.

* lavc/h2645_parse: Don't automatically remove nuh_layer_id > 0 packetsAndriy Gelman2020-01-171-1/+1
| | | | | | | | | | | | | | | | | | | HEVC standard supports multi-layer streams (ITU-T H.265 02/2018 Annex F). Each NAL unit belongs to a particular layer defined by nuh_layer_id in the header. Currently, all NAL units that do not belong to a base layer are automatically removed in ff_h2645_packet_split(). Some data may therefore be lost when future filters/decoders are designed to support multi-layer streams. A better approach is to forward nuh_layer_id > 0 packets and let blocks down the chain decide how to process them. The condition to remove packets has been moved to hevcdec and cbs.

| | | | | | | | | It's better to do it before the buffers are actually created. At least in VLC we currently don't support changing some parameters dynamically easily so we don't use the information if it comes after the buffer are created.

* avcodec/nvdec: Add support for decoding HEVC 4:4:4 contentPhilip Langdale2019-02-161-0/+3
| | | | | | | | | | | | | The latest generation video decoder on the Turing chips supports decoding HEVC 4:4:4. Supporting this is relatively straight-forward; we need to account for the different chroma format and pick the right output and sw formats at the right times. There was one bug which was the hard-coded assumption that the first chroma plane would be half-height; I fixed this to use the actual shift value on the plane. We also need to pass the SPS and PPS range extension flags.

| | | | | | | | | | | | | | HEVCSEIPictureHash should store only the information extracted from the bitstream and exported to the higher layer (the decoder or the parser). The MD5 context is allocated, used and freed by this higher layer, so it makes more sense for it to also be stored there.

| | | | | | | | | | | | | | | | | | | | | | | | Not all compilers can do alignment larger than the normal stack alignment for variables on the stack.
