Convolution Help

[simoncn]

The recommended way to install a newer version of ffmpeg is to download a static build of FFmpeg from this website, then extract the ffmpeg executable and copy it to the MinimServer/opt/bin folder on your Synology NAS. For a NAS with an Armada XP processor, you should download the armhf version.

Hello Simon, Thank you so much for your help.
Sorry to be a rookie on this.

Have a nice day !

Alternatively, if you select the Synology Package Center and browse the Community section, you will find ffmpeg version 4.1-11 available.
Installation should be straightforward from there and any subsequent updates will be alerted via Synology notifications.

My Synology Ds213j has this ffmpeg version installed in a directory that requires the following stream.converter input text value:-

/volume1/@appstore/ffmpeg/bin/ffmpeg

Either way you choose, good luck with invoking convolution.

By the way, out of interest, how are you intending to use convolution and how are you generating the convolution file?

Thank you both for your advices.

I have download and installed the ffmpeg static build for my Syno ARM, as you've indicated me Simon.
It worked after having restarted diskstation.
But when I'm entering the convout line in stream option, it returns an error message, as follows

I've tried with another output folder for my wav file (volume1/MinimServer/) but the result is the same.
It seems I still have an issue with the converter program, but now I know I'm pointing on the latest ffmpeg build. So what's the problem, I don't know.
I have the same issue when using the other ffmpeg installed on my NAS (as provided by Alandbush thx ) but the result is the same as well.

If ffmpeg is installed in the opt/bin folder, you don't need to set the full path in stream.converter. MinimStreamer will find ffmpeg there automatically and will set stream.converter to opt/bin/ffmpeg to confirm it has found ffmpeg there. This is not the reason for the error message, just FYI.

I don't understand why this isn't working (assuming that your convolution file is valid). Please produce a debug log by doing the following:

1) Clear the stream.options property
2) From the minim icon. select 'Show log'
3) In the log window, set the logging level to Debug
4) In the log window, click Clear
5) Leave the log window open
6) Set the stream.options property to: convOut= -i /volume1/music/MUSIC/conv/Cor1S44.wav -lavfi afir -v debug
7) You will get the red error message - this is OK
8) In the log window, click 'Save as' and save the log data to a file
9) Zip the saved log file and attach it to a post here

Hello Simon,

Here is my log file.

Just one precision : I've done the test with a basic .WAV music file which I have renamed.
I will get a UMIK microphone and use it with REW to generate a proper convolution file, but before buying this, I just would have been testing the function. Maybe I'm completely wrong and this the reason convout is not working. Sorry if my test is not relevent.

[simoncn]

The problem is caused by using a .wav music file instead of a valid convolution file. I have confirmed this by trying it with both types of .wav file.

Thank you Simon, Sorry for having wasted your time about this. Thank you for the confirmation anyway, i know that I can buy the UMIK microphone and perform the convolution by generating a valid convolution WAV file.
