Re: Cannot upgrade RPi4

Yes , as you cannot be sure what someone who might have accessed your Pi might have done. It is highly likely compromised. reflashing from a clean install is the only way to be sure nothing that shouldn't be there, isn't. botnets, crypto miners, viruses, keystroke loggers, just to name a few. Don't...

Surely we have to tell the system where the root file system is. Where would I find this in the docs?

Re: mplayer stopped working after latest ffmpeg update

You have to rebuild the package. This is much easier to do with mplayer (one package) than with ffmpeg which consists of lots of packages (libraries). I have downloaded the Raspbian source package, modified the control file and rebuilt (including recompiling) the package using the standard Debian to...

Thanks, gkreidl.

We'll either re-enable vdpau support in ffmpeg or disable it in mplayer.
Thanks! You should consider, that lots of packages dpend on ffmpeg libraries and there could be other applications with similar problems which we simply didn't find yet.

mpv is not a solution for me (for a number of reasons). The problem is related to ffmpeg's libavcodec.so.58 library as can be clearly seen from the error message.

no they aren't 4k. at best 1080p most of them are 720p.

Re: Avidemux on Raspberry Pi in Raspbian (Debian Buster)

Smart rendering means, that you can cut at any frame. This means, that small parts of the video have to reencoded (but not the whole video). One example: Cutting ads from TV recordings. To get a seamless cut, you need smart rendering - or you have to reencode everything. Older versions of Avidemux c...

The RPi H264 GPU codec is limited to one 1080p video. If you want to run multiple videos on the screen at the same time you have to reduce the resolution of the videos.

Yes, it can be done with tools from my kweb suite. I call it "simulated web video". It looks like the video is playing inside a web page, while in fact it's an overlay created by omxplayer(GUI).

You'll find more details in the developers chapter of my omxplayerGUI manual.
