* dnn: introduce dnn operand (in c code) to hold operand infos within networkGuo, Yejun2019-08-306-134/+236
| | | | | | | | | | | the info can be saved in dnn operand object without regenerating again and again, and it is also needed for layer split/merge, and for memory reuse. to make things step by step, this patch just focuses on c code, the change within python script will be added later.

* configure: fix --enable-omx compile on raspberry piAman Gupta2019-08-291-1/+1
| | | | | | | | | | | | | | | | | | | Many ffmpeg + rpi compilation guides on the internet recommend using `./configure --enable-omx --enable-omx-rpi`. This fails to find the IL OMX headers on device because the omx require_headers check happens first before the add_cflags in omx_rpi. A workaround is to use `./configure --enable-omx-rpi` only, since omx_rpi already implies omx. But because many users expect to use existing scripts and commands, we swap the order here so omx_rpi special cases are applied first. In the past this wasn't an issue because users noticed the OMX_Core.h missing error and installed libomxil-bellagio-dev. But since 76c82843ccad1, the rpi specific headers from /opt/vc/include/IL are required. Signed-off-by: Aman Gupta <aman@tmm1.net>

* libavcodec/amfenc: Vulkan initialization support for encoder.OvchinnikovDmitrii2019-08-274-6/+30
| | | | | | | | | | | | | | | | | | Added linux support for amf encoder through vulkan. To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and amf-amdgpu-pro package(amdgru-pro contains, but does not install automatically) are required. This driver can be installed using amdgpu-pro-install script in official amd driver archive. Initialization of amf encoder occurs in this order: 1) trying to initialize through dx11(only windows) 2) trying to initialize through dx9(only windows) 3) trying to initialize through vulkan Only Vulkan initialization available on linux.

| | | | | | | | | | | | | | change ff_reget_buffer() will attempt to create a writable copy of the frame, which is not needed when the decoder intends to return a reference to the same buffer as the previous frame.
