This function is implemented based on libva and currently supports H.264 and H.265 decoding, and will gradually support encoding and other profiles in the future.
Mesa on the guest side: mesa/mesa!17157
I played the following files using MPV player(--hwdec=auto/no):
| File | Desc. |
|---|---|
| bbb_sunflower_1080p_60fps_normal.mp4 | H.264+AC3+MP3, 1920x1080, 60fps, 339MB |
| bbb_sunflower_2160p_60fps_normal.mp4 | H.264+AC3+MP3, 3840x2160, 60fps, 642MB |
| caminandes_llamigos_1080p_hevc.mp4 | H.265+AAC, 1920x1080, 24fps, 27MB |
Here are the test results(use mesa-20.0.8):
On x86_64 (Intel i5-9500 + AMD Radeon RX550), the CPU usage:
| software decoding | hardware decoding | |
|---|---|---|
| H.264/1080p@60fps | 65.0% | 17.3% |
| H.264/4K@60fps | 108.0% | 17.6% |
| H.265/1080p@24fps | 42.6% | 9.5% |
On aarch64 (Kunpeng-920 + AMD Radeon RX550), the CPU usage:
| software decoding | hardware decoding | |
|---|---|---|
| H.264/1080p@60fps | 76.0% | 6.7% |
| H.264/4K@60fps | 321.0% | 8.4% |
| H.265/1080p@24fps | 63.7% | 4.1% |
