Problem transcoding - avconv

[titithebad]

Dear all,

I am using 5.1.5260 version on a Raspberry PI + with Jessie. FFmepg is no more supported and avconv is only available with :
"avconv -i %s -c:a libmp3lame -b:a 320k -f mp3 -" command line. I have change the line "audio->mp3" where FFmpeg is used with this command line.

The "audio->mp3" is selected for my profil.

My problem is when I download in cache the flac file on my phone with DSUB, the file is not coded in mp3. The file format is in Flac in the cache.

The

Is anybody know why ?

Regards
