    So, with the same cable and display the RPi4B working well and the RPi3B+ not. Maybe is something wrong with your RPi3B+. Did you tried with something else, like the "Raspberry Pi OS"? Just to check if with another OS you get the same issue. I'm using now RPi3B, RPi3B+ and RPi4B (now with the latest LE12 nightly), and only once had a display detection issue (last year, cheap bad HDMI cable).

    You might be right about this. I tried different displays and cables and it's always the same, 4B shows HD resolutions and 3B+ only up to 1024x768. The streaming blur seems to be a different problem though, because other videos still play correctly despite the resolution issue.


    Bingo! RPi4 can play 4K, but RPi3B+ can't. That's part of the official hardware specs.

    Please pastebin a Kodi debug log that shows this stream being played.

    Even 640x480 stream showed the same problem on the 3B+. I will upload a recording and log later when I get to it.

    Hi, I didn't seen any 16:9 display with 1024x768 max resolution (the 1024x768 isn't a 16:9 resolution at all). What's the maximum display resolution detected with RPi4B and 3B+? Looks like the 3B+ using only max. 1024x768, and if the display able for something better, it's a display detection issue there (HDMI cable?). Could you try with an another HDMI cable and/or display? Probably that isn't the main issue, but should be clarified to exclude any conection with it.

    Different cable and display show same result. Only those three 4:3 resolutions are available on 3B+, even after fresh installation on formatted SD card.

    The 4B connects at 1920x1080 automatically with the same cable. But I agree, this is probably a secondary issue.


    You could try overclocking. If not working afterwards, post the media info of the stream.

    Is it a security camera?

    Yes, an IP camera offering RTSP steam. The information window in Kodi player only says "Not available" and below:

    H.264 / 4K / 1.78:1 / AAC / 1.0


    The display pipeline on RPi0/1/2/3 is 1920x1080 maximum and supports a specific set of configurations. The much newer RPi4/5 can handle 4096x2160 max and a wider variety of configurations.

    If you can capture/share some examples of the stream we can look deeper.

    Just to be clear, by capture examples you mean screenshots`?

    The monitor is actually 16:9 and supports a higher resolution. The 4B also makes use of this, but the 3B+ only offers 640x480, 800x600 and the selected 1024x768. I couldn't get it to set higher one, or any in the correct format.

    Still this doesn't seem to be the only problem. I tried a 640 stream and still got the blur for most of the screen (about two third, interestingly the top third works quite well, and below that it blurs).

    Hi everyone! I have two RPis, a 3B+ and a 4B. Both have latest LibreELEC installed. When I open a local RTSP stream via strm file, the 4B plays it correctly, while the 3B+ opens the video player without playback and only shows black screen.

    The log shows only one error, which I can't make sense of or find anything useful online: CVideoLayerBridgeDRMPRIME::Map - failed to add fb 0, ret = -22

    A fresh new installation did not help. What else can I try? Thanks in advance!
