AMD's amf in ffmpeg
by Andrew Randrianasulu 12 Dec '24

12 Dec '24

As Terje requested I looked up into amf compilation, _it seems_ it just require headers at compilation stage BUT amdgpu-pro runtime for any real use, and it goes via vulkan anyway ? https://ffmpeg.org/general.html#AMD-AMF_002fVCE

Video accelerators support, builds and use
by Terje J. Hanssen 11 Dec '24

11 Dec '24

To clarify some pieces once again, I put up some basic statements or questions: For an end-user to utilize video acceleration support, he/she need a computer with supported graphical hardware with libs/API and drivers for it(?) The libs and drivers can be dynamical linked (enabled) to the system or static built (embedded) in CinGG? So what happened when adding oneVPL (qsv) support to the build system; dynamic linked to system or static added embedded into the build? If oneVPL was dynamic linked, the qsv support may be be distribution specific, or if static built it will be generic available on compliant hardware? Is it correct to say the build machine does not need the specific graphical hardware, but needs the actual graphic libs installed to build Cingg with it? Could in principle similar methods be extended to include broader video acceleration support for AMD/amf and NVIDIA/nvenc? -------------- So a confusing piece if "oneVPL" instead should have been replaced with "libvpl?, because I just read /Note for Users of Intel® oneAPI Video Processing Library (oneVPL) and for Intel® Media SDK/ /https://www.intel.com/content/www/us/en/developer/tools/vpl/overview.html/ /oneVPL is now called the Intel® Video Processing Library (Intel® VPL). The library will no longer be part of the oneAPI specification so that Intel can focus on providing video processing features on Intel GPUs./ In comparision on openSUSE/Slowroll on Intel, there are libvpl(2) (and no oneVPL). /The oneAPI Video Processing Library (oneVPL) provides a single video processing API for encode, decode, and video processing that works across a wide range of accelerators. / ffmpeg similar has --enable-libvpl --enable-vaapi --enable-vdpau --enable-vulkan / /

Checked into GIT several hardware specific mods
by Phyllis Smith 10 Dec '24

10 Dec '24

Outcome from all of the hard work that Andrew did with Terje for the newer Intel hardware performance enhancements has been checked into GIT. Here is a rough description of what was checked in. - 12 new or replaced "vaapi" encoding render formats (vainfo shows if supported) - 12 new or replaced "qsv" encoding render formats (requires Intel HW build) - patches to ffmpeg.C and ffmpeg.h to support the above - 3 new Termux (Android) encoding render formats - 2 mediacodec which will only work on Android + an mpeg one that works everywhere - mjpegtools patch to accommodate clang compiling continuance There should be no impact to standard usage of CinGG but users need to be especially aware of the fact that using a render encoding format that requires specific hardware/software implementation will give an error. In addition, the standard appimage releases will not provide the availability to use this Intel hardware. This is the same as the inability to use vdpau/vaapi from those same appimages since the appimages are created on a computer without the end users same hardware. I need to update the Manual to make this clear in the Hardware video acceleration section.

x265 4.1 is out for some time ...
by Andrew Randrianasulu 09 Dec '24

09 Dec '24

https://x265.readthedocs.io/en/4.1/releasenotes.html reverted some of 4.0 api changes, so our ffmpeg patch for this probably not needed anymore if we decide to update. Memleak fixes also. https://bitbucket.org/multicoreware/x265_git/downloads/x265_4.1.tar.gz

OT: GPU-Viewer - A GUI front-end to glxinfo, vulkaninfo, clinfo and es2_info.
by Terje J. Hanssen 02 Dec '24

02 Dec '24

/"This project aims to capture all the important details of glxinfo, vulkaninfo and clinfo in a GUI. The project is being developed using python 3 pygobject with GTK4. All the important details are extracted using glxinfo/vulkaninfo/clinfo with the combination of grep, CAT , AWK commands and displayed in the front-end. There is no hard OpenGL Programming involved, until glxinfo, vulkaninfo and clinfo works the GPU-viewer will also work" /https://github.com/arunsivaramanneo/GPU-Viewer https://arunsivaramanneo.github.io/GPU-Viewer/ https://linux.softpedia.com/get/System/Monitoring/GPU-Viewer-104591.shtml There are DEB based and Arch packages. Thanks to malcolmlewis at openSUSE Build Service who has build it for Tumbleweed/Slowroll.

test patch for 7.0 ffmpeg
by Andrew Randrianasulu 20 Nov '24

20 Nov '24

It may work or break it completely ... apply by normal patch command from inside thirdparty/ffmpeg (may be "cat pathname | patch -p1", may be "cat patchname | patch -p0") or edit libavcodec/qsvenc.c by hand. rebuild ffmpeg, do not do make clean, cd ../../ so you again in main directory with ./autogen.sh and bin directory with cinelerra. touch cinelerra/ffmpeg.C make Hopefully this rebuild cin so on next start from bin/cin you will have something to test with tff sources. Unfortunately, netBSD does not support hardware virtualization on AMD cpus, so for now I do not have my virtual machines. I also forgot type of cable from PSU to disks, so now I can only power up one of two sata drives. It will be fixed eventually, but for now I hope to live up this netBSD install a bit ...
