mplayer and ALSA audio

iMxGuy — Fri, 23 Sep 2011 16:09:50 GMT

Hi,

mplayer is not outputing audio to my sound device. I am able to play sounds using aplay and mp3play, but with mplayer I get no sound. mplayer -ao shows the following output. I don't see ALSA listed. How can I get ALSA support for mplayer?

Hi,

the following helped for me, though I worked on a ubuntu platform

For Mplayer Alsa-support you'll need the libasound2-dev

If you run the mplayer ./configure script it will report

Checking for ALSA audio ... yes (using alsa 1.0.x and alsa/asoundlib.h)

Greetings,

I should have said, I was running mplayer on our i.MX28 board, not on my host machine.

Hi,

I assumed this ;-) I added the mplayer package in ltib and built it for the target imx28evk. Below you can find the configure output during ltib build of the mplayer package. As you can see, the ALSA lib was not found. So I guess that the development libraries/sources e.g. libasound2-dev and the header file alsa/asoundlib.h are missing.

Cheers,

cd mplayer-1.0~rc2
