Cannot set installed Ffmpeg as converter

[ditusade]

Hi,
I installed ffmpeg for another audio program which works fine for its purpose. The executable sits at /usr/local/bin/ffmpeg.
Minimstreamer converter would not accept this path. I also copied ffmpeg to /opt/bin but no joy. I also changed the filename permissions to be accessible to everyone again nothing.
In ssh, i can run ffmpeg from anywhere. Any other thing I can try please.

I don't want to install another ffmpeg as my other audio program doesn't like it.
My system - Raspberry Pi 5 running Ubuntu 24.04 (RT Kernel) .

Thanks
Dave

Please post the output from running your version of ffmpeg from a terminal window with no arguments.

Thanks for this information.

When MinimStreamer starts, it does some test invocations of ffmpeg to make sure that the ffmpeg executable provides the capabilities that MinimStreamer needs. This is needed because ffmpeg can be built in many configurations with various features disabled.

The terminal output you have posted shows that the version of ffmpeg you are using is heavily customised to disable certain features that are available in a standard ffmpeg build. Because of this customization, one of MinimStreamer's test invocations is failing.

To solve this you will need to use a standard build of ffmpeg to run MinimStreamer. You can put the standard build in the MinimServer opt/bin directory to prevent it from being visible to any other programs.

Thanks for identifying the root cause Simon. Wil follow through.

Downloaded the pre-built executables from FFMPEG build site. Copied ffmped to /opt/bin and set the folder in Minimstreamer and now all works well. Thanks for the help

Thanks for confirming. Actually I was suggesting putting this version of ffmpeg in the minimserver/opt/bin directory, not /opt/bin. MinimSthreamer will find it automatically in this location without needing to set the stream.converter property and it is completely private to MinimServer/MinimStreamer.

It works where you have put it but it's a bit tidier to do the above.
