What is Vaapi driver?
VAAPI (Video Acceleration API) is an open-source library and API specification, which provides access to graphics hardware acceleration capabilities for video processing. It consists of a main library and driver-specific acceleration backends for each supported hardware vendor.
What is hardware acceleration video decoding?
Hardware video acceleration makes it possible for the video card to decode/encode video, thus offloading the CPU and saving power. Video Acceleration API (VA-API) is a specification and open source library to provide both hardware accelerated video encoding and decoding, developed by Intel.
How do I check Vaapi?
Decoding: sudo apt-get install i965-va-driver libva-intel-vaapi-driver vainfo Then setup vlc to use hardware decoding, run it from the command line (to get the debug messsages) and open am . mp4 file. You should see: [0x1781058] main libvlc: Running vlc with the default interface.
Which is better software or hardware decoding?
Hardware decoding is faster but doesn’t support as many file types. Software decoding is flexible and can support many media formats, but it’s slower. Hardware decoding in general can also lead to glitches/artifacts in the video.
What is the best encoder for recording?
For recording, use a hardware encoder (nvenc, quicksync) with quality-based rate control (CQP, ICQ, CRF) and no bitrate-based rate control (everything with BR in it). Use a quality setting of about 18-21. This gives a quality almost indistinguishable from the original and has no CPU power demand.
How many encodes can I run with VAAPI?
Unlike Nvidia’s NVENC, there are no simultaneous encodes limitations on the consumer SKUs. I was able to run 10 encode sessions siumultaneously with VAAPI, whereas with NVENC, I’d have been limited to two maximum simultaneous encodes on the GeForce GTX series GPUs on the testbeds.
How to get ffmpeg to encode with VAAPI?
It’s a prerequisite to building libva with the desired configuration so we can access VPX-series hybrid decode capabilities on supported hardware configurations. This package provides the VA-API (Video Acceleration API) user mode driver for Intel GEN Graphics family SKUs.
How can I test the VAAPI supported featureset?
When done, test the VAAPI supported featureset by running vainfo: The output on my current testbed is:
Can you use VAAPI on an AMD A10?
I would like to use the VAAPI hardware encoding working on my AMD A10-7870K APU (with a Radeon R7 integrated GPU) with Emby 4.0.0.2 running in a Docker container. I believe I have set up everything correctly, but the hardware detection script is returning an error code.
