  • What does "100" inside a blue circle mean? RPi4 freezing

    Quote from Michael_B

    Disabling DRMPRIME in the expert settings solved the problem for me.

    I wasn't aware that the hardware decoders can have such an impact on system stability. If the decoder stops playing my (maybe broken/non-standard) ile -> ok. But, freezing the whole RPi4?

    Can you be more specific. There are a few combinations of options here that will narrow it down. You have:

    1) Allow using DRM PRIME decoder

    2) Allow hardware acceleration with DRM PRIME

    3) PRIME render method

    The default is 1=enabled, 2=enabled and 3=direct which you've reported as hangs

    Can you test:

    1=enabled, 2=enabled, 3=EGL

    1=enabled, 2=disabled, 3=direct

    1=enabled, 2=disabled, 3=EGL

    1=disabled, 2=N/A, 3=EGL

    As chewitt says, provide us with an example file. Ideally cut one down to a couple of minutes, confirm issue still occurs and upload it somewhere (e.g. google drive).

    If you believe it occurs with all files, then can you test a publicly available file (e.g. Big Buck Bunny and confirm you still see the issue?

  • Video Orientation

    If you disable "Allow using DRM PRIME decoder" in settings/player/video then the orientation flag is supported.

    But performance will be lower.

    I think on the nightly builds, you can leave that setting enabled but change "PRIME Render method" to EGL,

    which will have better performance (but still not as good as using DRM for rendering).

  • LibreElec 10.0 B1 RPi4 switch audio to analog output (3.5mm jack)

    It may be possible to setup dual audio using pulseaudio combine-sink. See here:

    Post

    RE: Libreelec 10.0.1 on RPi-4B : Simultanous output to HDMI and Bluetooth Box?

    it works for me

    my /storage/.config/autostart.sh :

    pactl load-module module-udev-detect

    pactl load-module module-combine-sink slaves=alsa_output.0.hdmi-stereo,alsa_output.3.iec958-stereo



    however I have 2 problems

    1) playing video create sometimes echo artifacts (crackling) on hdmi output

    2) playing spotify plugin librespot? causes lagging / pitch during palyback

    Not sure if this is pulseaudio problem or HW is just too weak to send audio to 2 sinks.. (RPi3)

    anyone knows?b

  • LE 11.0.1 & 4K TV screen flicker, no problem 4K Monitor

    Quote from Nahannidog

    3. With old cable and 4KTV, I had flicker problems until resolution dropped all the way down to 720x576!!!! Any guesses as to why the old cable performed so much more poorly (poorly only with RPi4 & 4KTV, fine with RPi4 & 4K Monitor)? The microHDMI connector seems like a weak link, being so tiny. Or maybe 4KTV spews alot more EMI and old cable was poorly shielded?

    The usual reason is thin wires, which means high resistance, which means significant voltage drop (and that is more significant with the higher resolution, higher clock frequency hdmi modes).

    This video may be illuminating showing just how many random hdmi cables are sub-par.

  • LE 11.0.1 & 4K TV screen flicker, no problem 4K Monitor

    My guess would be the HDMI cable. 4kp60 requires a very high clock rate and that needs a high quality cable.

    Just because it works on another TV doesn't guarantee the cable is perfect (the other TV may just be better and handling a low level noisy signal).

    But as chewitt says, follow the recommended instructions and you'll rarely be running at 4kp60 (most video content is 24fps) so are much less likely to hit the issue.

  • RPi4 62Hz Refresh problem

    Quote from jcjefferies

    I think I was a bit hasty saying the new RPi4 was faulty. I have configured the mains so I can switch on the TV first and view the full boot sequence. Running 11.0.3 on one TV I am using to test bootup the first display frequency is 1080p 60Hz next 1366x786 62Hz for most of the boot sequence then 720p 50Hz which is the resolution in system settings! On this TV during the 62Hz time the display is torn and unreadable. In normal use with this RPi4 if this TV is not taken out of Standby within 5 seconds the screen locks up! Another TV displays nothing if this RPi4 is connected.

    I'm not entirely understand the sequence of events here.

    For TV's that don't provide an EDID when powered off (many but not all do),

    you should power the TV on and select the correct AV input first.

    Assuming you have done this, then I'm not sure how this occurs:

    > In normal use with this RPi4 if this TV is not taken out of Standby within 5 seconds the screen locks up!

    So, does the TV behave as desired when it is powered on and switched to correct AV input before powering on the Pi?

    If yes, then then getedid create will make things much smoother in future (order of powering on won't matter).

    If no, then post a debug log.

  • Youtube and Tubed errors

    Looks like carsten888 has found the answer here.

    (It's always better to check for the official addon thread on the kodi forum).

    But for anyone else, the repo version of YouTube is broken and there is a fixed alpha version which you need to update from zip file.

    (which for some reason has been working fine for a couple of months but hasn't been pushed to stable).

  • Playing 4K Video on 1080p TV

    Quote from symean

    For that to work properly do I need to whitelist the modes the tv supports?

    It will work whatever you do. Enabling "adjust display refresh rate to match video" is recommended for smooth playback.

    You can use the whitelist, but if the display is 1080p, then it will use 1080p for gui and for video playback which is what you want anyway.

  • Playing 4K Video on 1080p TV

    The is no problem with 4k decode and downscale to 1080p.

    But you may hit a problem with HDR.

    HDR is pretty common in 4k hevc files.

    HDR is pretty rare on a 1080p display.

    With this combination the video will play, but the colours will be off (it looks a bit over exposed with muted colour).

  • Video File Crashes LibreELEC 11.0.3 on Raspberry Pi 4

    Quote from bikeseat

    Haven't had a chance to try LE12 nightly, but glad to hear it doesn't seem to crash it.

    I think whether it crashes or not on a given platform is just luck - whether the invalid pointers accessed happen to point to previously allocated memory or not.

    kodi didn't crash for me on RPiOS bookworm (using ffmpeg 5.1.3) but did on Ubuntu 23.04 (using ffmpeg 5.1.2).

    But feel free to try LE12 and see if it is more reliable.

  • Video File Crashes LibreELEC 11.0.3 on Raspberry Pi 4

    I tested this file with mplayer on my x86 Ubuntu laptop.

    It played for a while then got very confused

    and crashed here:

    It may be best to report this to ffmpeg - it is not a Pi specific or kodi/libreelec specific issue.

  • Pi4 crashing while playing video

    Quote from Crackbat

    chewitt Do any of these logs help with figuring out the issue? I have not been able to pinpoint it myself yet. It only seems to do it for some video files, and at the same times on the files. So I am assuming my Pi is just having issues with certain video codecs? Maybe?

    I think it is more likely a network issue.

    Copy a problematic file to local storage (sdcard or usb stick) and play it.

    Does it also stop in the same way? If it does there is a video codec issue (and a sample file that exhibits the issue can be analysed).

    If it doesn't it suggests a network issue that would need a very different diagnosis.

  • Recommendation on new hardware

    Quote from shedrock

    I am not sure if I would have to use an external SSD drive on the RPI4, and in doing so, would that not be a slower option to run LE, as oppose to the Micro SD drive, which appears to be insufficient in regards to capacity?

    An SSD will typically be faster than a micro SD card.

    sdcards can be up to 1TB, so it's not limited in capacity, but I wouldn't recommend an sdcard that large.

    An SSD is likely cheaper and faster at that capacity.
