Audio ALSA support #101

Closed magdesign closed 6 years ago

magdesign commented 7 years ago

Since original omxplayer supports ALSA sound, for example: omxplayer -o alsa:hw:1,0 /location/of/video.mp4

It would be amazing to get also ALSA support on ofxOMXPlayer.

Oh wow, I totally missed that they implemented that! Big +1 for adding alsa support for ofxOMXPlayer. By far the biggest issue I usually have.

I think this will never come :-(

jvcleave commented 7 years ago

@magdesign yes - I've been on other non-RPi projects so it's unlikely to come from me.

Hey all,

with the rehaul the OMXAlsa stuff is there but may need some tweaks to be enabled? I'm not sure what the application use is as I typically just use the HDMI port.

jvcleave commented 6 years ago

the way you can enable it is to use

omxPlayer.engine.m_config_audio.device = "omx:alsa";

before calling omxPlayer.setup();

on my config is it currently causing errors and stopping video from playing but the component is passing. I don't know if I need other config tweaks in order to work as expected

timonsku commented 6 years ago

Odd but would definitely be great to have! Main use is having an i2s audio hat or a usb audio interface.

jvcleave commented 6 years ago

ok - i do have a usb sound card so I can try that. It's probably just a matter of passing the correct hardware id

jvcleave commented 6 years ago

it does work - use the syntax

omxPlayer.engine.m_config_audio.device = "omx:alsa";
omxPlayer.engine.m_config_audio.subdevice = "hw:1,0";

//works but sounded weird with my config
//omxPlayer.engine.m_config_audio.subdevice = "default";
