I was able to get a video to play on PiStorms using this tutorial: https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/playing-videos

Great!!!

how to watch the video using the HDMI output?

wget http://adafruit-download.s3.amazonaws.com/bigbuckbunny320p.mp4
sudo apt-get update
sudo apt-get install mplayer
sudo SDL_VIDEODRIVER=fbcon SDL_FBDEV=/dev/fb1 mplayer -vo sdl -framedrop bigbuckbunny320p.mp4

Cheers

Use FRAMEBUFFER=/dev/fb0? I've never actually done this, so you will have to figure it out for yourself. Surely there is some web page about this already.

Hi, I tried but I receive the following error:

robot@ev3dev:~$ FRAMEBUFFER=0
robot@ev3dev:~$ sudo mplayer -framedrop bigbuckbunny320p.mp4

You for got export.

export FRAMEBUFFER=0

Also, you should not need sudo. Just make sure you are on a terminal running on the HDMI already.

[jabrena]

nope, with this configuration the video is showed on the terminal.

robot@ev3dev:~$ export FRAMEBUFFER=0
robot@ev3dev:~$ mplayer -framedrop bigbuckbunny320p.mp4

[dlech]

This is expected if you run the command on a remote (ssh) terminal. You have to be logged on to a virtual console on the the HDMI output itself.

Is it possible to test the same example on the EV3 Brick?

I tried with:

sudo SDL_VIDEODRIVER=fbcon SDL_FBDEV=/dev/fb0 mplayer -vo sdl -framedrop bigbuckbunny320p.mp4

But I couldn't do it.

[dlech]

Afik, SDL does not support monochrome (1-bit per pixel). You have to use something else. Maybe you could ask this person how they played video on the EV3.

Maybe AAlib with a 1x1 font? I'm trying to play Doom on it.
