Hardware H264/H265(HEVC) decode acceleration for Raspberry Pi 4 64bit #129

Open MELSunny opened 2 years ago

MELSunny commented 2 years ago

Raspberry pi officially announced the 64bit OS on Feb 2022. On 64bit Raspbian, I found the following hardware acceleration is available on ffmpeg of rpi's distribution RPi-Distro/ffmpeg. H264 decode/encode H265 decode

It just need a single commend to enable the V4L2 decoder. (For more informations: jc-kynesim/hello_drmprime) sudo dtoverlay rpivid-v4l2

I downloaded two sample h265 videos 

wget http://www.jell.yfish.us/media/jellyfish-3-mbps-hd-hevc.mkv
wget http://www.jell.yfish.us/media/jellyfish-3-mbps-hd-hevc-10bit.mkv

and tried to convert videos from h265/h265-10bit to h264 with RPi-Distro/ffmpeg, here is the output.

ffmpeg -hwaccel drm -i file:"jellyfish-3-mbps-hd-hevc.mkv" -codec:v h264_v4l2m2m -b:v 16M -codec:a aac -f mp4 jellyfish-3-mbps-hd-hevc_converted.mkv

RPI4/4GB(RAM) CPU load usage during the conversion is around 0.9 on average, and the converted videos can be correctly played. However, jellyfin-ffmpeg is not working with the following error. I am grateful if jellyfin team could provide hardware encode acceleration for RPI, and make the RPI a cost-effective home media centre with jellyfin.

da-anda commented 2 years ago

is the linked blocker the reason why there is no "enable h265 HW decoding" setting in JF atm? h264 is already available.

PimTournaye commented 2 years ago

Hi, has there been any progress towards this on this side of things? Sadly don't know enough about low level stuff to help out with this, but if I can help any other way, please let me know.

Arthedian commented 1 year ago

Hi, @nyanmisaka could you please tell us if there is any progress? It would help a lot.

nyanmisaka commented 1 year ago

@Arthedian This has been blocked by the fact that scale_v4l2m2m video scaler it not available in upstream. I'm not versed in Linux V4L2 and the closed source Broadcom GPU so you'd better turn to https://github.com/jc-kynesim/rpi-ffmpeg for help. It seems the author jc-kynesim is an employee of the RPi Foundation.
