Streaming video through Flaschen Taschen to rgb led matrix

[dennismamedov]

Hey!

I'm trying to setup flaschen taschen for my led matrix but I can't seem to stream the vlc to the udp server. I'm running: vlc --vout flaschen --flaschen-display=localhost --flaschen-width=64 --flaschen-height=64 "https://www.youtube.com/watch?v=QH2-TGUlwu4" --no-audio I'm getting:

VLC media player 3.0.10 Vetinari (revision 3.0.10-0-g7f145afa84) [01e52db0] vlcpulse audio output error: PulseAudio server connection failure: Connection refused [01e775c0] main interface error: no suitable interface module [01dd7b58] main libvlc error: interface "globalhotkeys,none" initialization failed [01dd7b58] main libvlc: Running vlc with the default interface.

Initialising the server with: ~/flaschen-taschen/server $ sudo ./ft-server --led-slowdown-gpio=4 --led-cols=64 --led-parallel=2 I built it with: make FT_BACKEND=rgb-matrix any idea?

Have to say that simply running vlc "any youtube link" works, only when i use flaschen it gives me that error.

Hi @DennisMamedov - not sure if you figured things out. It seems most likely to be down to UDP limits. See the answer here for details relating to VLC / UDP size limits: https://github.com/hzeller/flaschen-taschen/issues/61#issuecomment-886252029

As a temporary work-around / test, if you try using a smaller values for width and height, you should see an image come through (assuming everything else is working)

vlc --vout flaschen --flaschen-display=ledframe --flaschen-width=40 --flaschen-height=32 "https://www.youtube.com/watch?v=XXXXXXXXX" --no-audio

(edit: added the link to the answer, which had been left out by accident!)
