RPi4 troubleshooting

    Hi,

    I have a RPi4 running 10.0.3. When I try to play 4K content it is choppy and unwatchable (I do get source is too slow messages). Regular HD is OK.

    Connection is 1Gb.

    I have the RPi connected to the same switch my workstation is connected to. If I play the same video file on my workstation using VLC it plays flawlessly. VLC shows 0 lost/corrupted frames, even after playing for an extended while.

    File info using Mediainfo:

    Logs from the RPi are attached.

    Is this too much for the RPi?

    I noticed a couple of things:

    First of all you are running LE 10.0.2 - please test with the current 10.0.3 release

    You seem to have connected the HDMI cable to the wrong HDMI port of the RPi - use HDM0 as HDMI1 has limited capabilities.

    You seem to be playing through the emby addon - have you tested with SMB or the file copied to a USB pendrive / HDD?

    You didn't enable debug logging and from the looks of it also not adjust refresh rate, together with whitelisting the important modes as described in the wiki. Please to the latter, permanently, and the first when you still have issues after the steps above.

    Then upload the logfile either with the log upload function in LE settings or with "pastekodi" via ssh - the logfiles via the SMB share are unfortunately missing important info (guess we should fix that...)

    so long,

    Hias

    How do I upgrade to 10.0.3? I'm normally in auto update and it hasn't updated automatically past 10.0.2. If I set update to manual it doesn't show as a version.

    Tried using the other HDMI port but no change (I did reboot).

    Tried using a normal added video source (non Emby) but that didn't change anything. The video name for that test is Testvid.mkv and is a copy of the original 4K movie. FWIW I have Emby set to use native paths.

    debug log is at http://ix.io/4gS3

    Oh, this does appear to be a resource issue on the RPi4. When in debug the CPU usage is consistently in the 90% on all 4 CPUs and regularly will hit 100%.

    I've been using NFS. I added another source to access the TestVid.mkv file using CIFS (direct, not Emby). Same result.

    Edited 2 times, last by TugboatBill: Merged a post created by TugboatBill into this post. (November 25, 2022 at 10:12 PM).

    I updated to 10.0.3. Turned on debug and started the mkv from the non Emby source. Problem is still there.

    Here is the debug log http://ix.io/4gSd

    Here are the results from "top" and "perf top" while displaying the TestVid.mkv video from the non Emby source (SMB).

    It seems ffmpeg is using software decoding which is too much for 4k - please verify if settings->player "Allow using DRM Decoder" and "Allow hardware acceleration with DRM PRIME" are both at the default (enabled) and "PRIME Render Method" is also at default (Direct To Plane)

    so long,

    Hias
