Re: Setting up Pi4 as dedicated 4k looping video player

Except for H265 all RPi HW decoders only support 1080p videos. Currently the H265 decoder is only available for Kodi (on Raspbian) or LibreElec.

Re: Memory management question

Using different swappiness values makes no difference at all, even setting it to 0. I've tried 0, 1, and 20 and cannot detect any difference. The RPi starts swapping after a while although I use only 300MB to 1GB on a RPi 4B/4G. This was definitely different on Stretch or Jessie. top - 12:01:42 up 2...

Re: Memory management question

There may be a bug in Raspbian Buster. I've tried different swappiness (and cache_pressure) settings and it doesn't seem to make any difference.

Re: My RP2 shows the video extremely slow while my RP4 shows it perfectly

The Pi 2 is significantly less powerful compared to the Pi 4. For that reason you have to be more mindful of the resolution and codec of what you're trying to play. For example, if your codec is heavily compressed, the Pi 4 can handle it, but the Pi 2 may struggle to keep up. Try converting whateve...

youtube-dl has its own, internal update mechanism. You simply invoke it with youtube-dl -U . Of course you need to run it as a user who has write permissions to the executable. I have it in my home folder in a subdirectory. This only works with the all-in-one version (which contains all modules wit...

Re: [Guide] Kodi on Raspbian Buster

I wanted to document a problem I've run into. I kind of assumed when I bought the Pi 4 that the reason VC-1 hardware decoding was dropped was that the new processor was powerful enough to handle 1080p VC-1 video. (At least, you'd hope it was tested before hardware support was dropped.) Buttttt that...

Ich habe 4 RPis an meiner Fritzbox (z. T. über einen Switch). Als ich Buster auf einem RPi 2B vorbereitet habe (SD Karte + HDD) und dann diesen RPi 2 durch einen Rpi 4B ersetzt habe, kam die Fritzbox durcheinander.

It may be compiled with support for MMAL or OMX, but it will miss all HW acceleration inside windows, as this has been added by RPT.

Re: Pulseaudio disturbs hdmi signal to tv and causes tv to blank/reconnect?

You have not told us, which media player you are using (on Raspbian). Kodi (using Libreelec or Raspbian) and omxplayer can switch the video resolution when playing video to match screen and video resolution and FPS. This might cause the effect you describe. It can be disabled in Kodi.
