Please keep us updated! Very curious to see how it does with the updated gpu.

Looking forward to some 4K transcoding benchmarks!
LOL that was my first thought. Can Jellyfin transcode 4K to 1080p with this new hardware for streaming. I’m hoping OP gives it a shot.
Same. I'm running JF on a Pi3b with 1GB ram rn
I believe you mean a jellyfin server (as opposed to some jellyfin client), right? Does it serve you as good as it should? Of course transcoding is off-limits, but does 1080p streaming run smoothly on the client(s), even with high bitrates?
That's correct yes. The server runs fine I average a load of less than 1 during a stream. However I do have to use the Applications as using the web interface for the larger files really chugs along.
Thanks for clarifying. So serving video while serving the webinterface is asking too much of it? Or is the bottleneck actually in your client device?
Yeah, the decoding is too much. So offloading it to the device makes more sense. My average load while streaming is 0.5
Please also check the power consumption. It is my understanding that the Pi5 does not have dedicated hardware codecs anymore except for HEVC/H.265.
Did the Pi4 have more hardware transcoding capabilities? I thought it was just those codecs as well.
I've got my info from here, look under "Media Decoding": https://libreelec.tv/2023/09/28/rpi5-support/
BCM2712 supports HEVC 4K60 hardware decoding. It no longer supports H264 in hardware. This might sound odd but it removes the RPi4’s 1080p restriction on H264 decoding and the 4K H264 test media we have has played. The big increase in performance from the Quad-Core A76 chip means RPi5 can software decode AV1, H264, VC1, VP9, and more at 1080p with ease. In our testing with YouTube and inputstream.adaptive a surprising amount of 4K media also plays. Optimised (lower refresh-rate and bitrate) 4K30 VP9 is generally fine while more demanding 4K60 VP9 content is not possible; it will play but frames are being dropped.
@Lemmchen I do not have any tools currently to do power consumption - however I will think about getting one before the #RaspberryPi5 ships
I think the Pi5 has a vcgen command to output power consumption, but I'm not sure it's available for the Pi4. Just an idea to play around if you're interested.
