problems with vlc on a raspberry pi

[mvaterlaus]

hi guys,
I don't know, if this is the right forum. I have a problem with vlc on my raspberry pi. It won't display any videos. I compiled vlc and ffmpeg with the following use flags:

Code: Select all

testpi ~ # emerge -pv vlc ffmpeg

These are the packages that would be merged, in order:

The USE flags are the same as on my desktop, and my desktop shows the videos without any problems. On the pi, vlc starts to display the video, but I can't see any images.
First I tought, maybe the pi has not enough gpu memory, so I configured more in config.txt as follows:

Code: Select all

testpi ~ # cat /boot/config.txt 
# Display mode
hdmi_group=2
hdmi_mode=16

# GPU Memory (Default is 64MB)
gpu_mem=256

I used hdmi_group=2 because otherwise the monitor would not be filled over the whole screen. Also, I do not use any DE for the pi, only plain X.
It would be great, if someone could lead me in to the right direction or give me a clue where to look for this problem.

256MB for the GPU should be sufficient since I run XBMC on an old 256 MB raspi with 128MB for the GPU. Unless I am completely wrong an basic X environment should be sufficient. What I do not know is if VLC is of any use on a Raspi since it does not support hardware decoding from the GPU. The Raspi CPU itself does not have a lot of power. So playing back anything demanding will most likely be no fun

I run Raspian on my Raspi and omxplayer. With -o hdmi I can play back 1080p stuff via HDMI controlled from an ssh session. Work like a charm.

For more on mplayer under Gentoo without X you might consider reading this:

HTH....

hi HolgerB,
thanks for pointing that out. for now I will first try to install mplayer, since the dependencies are less than installing layman for getting omxplayer from the overlay. I will report back, if I have any luck.

Layman doesn't have much dependencies unless you intentionally enable them all, just enable the one you need for the overlay if you want or need to give omxplayer a try.
