I don't have any clue where to search but if it can help I paste you below the logs from console (when I execute the piece of code mentionned above) because it is different from what is written into uwofl.log output file.

@TotalSonic love it !

@TotalSonic @Lakotaubp thanks for your answers and tips
Futify would be the best option of course !!

Hello everyone,
first of all I know this app is still in development so I'm not here to put pressure in any way.
I just wanted to know if there is a way to solve this issue (see enclosed) that happens just after login my premium account.
Thanks a lot
Amaury

@naratip_prachai very nice to hear that !
By the way, if you are searching for apps to repare, the futify app login into spotify server is broken...

Hey ! here videos capture is possible but without any sound

@Bolly yes thanks ! This exactly what I did, and it worked
I've tried to install ffmpeg on UT to be 'autonomous' with snap but didn't worked

@domubpkm thanks, doesn't work with .avi

@Vlad-Nirky thanks !
Yes I've thought of vlc but waydroid with convergence isn't good.
I didn't found any snap also for vlc.

Is there a list of supported format by multimedia player ?

@MrT10001 said in Multimedia player:

Just played .mkv file fine, but .avi files would not play.

good to know then, I'll try .mkv

@arubislander what is codec ?

@MrT10001 .avi

@MrT10001 ok then we can consider there is no DRM

@MrT10001 no idea. How can I find out ?
