[question] Can I casting Linux Application Window and sound with mkchromecast ?
I want to cast my favorite game from far away. Google Chrome and chromecast can cast image only (no sound). Can I cast image and sound at the same time using mkchromecast?
With the --screencast you can achieve casting your whole screen to your chromecast but with some delay. It will cast sound as well, but I think it is only working with pulseaudio.
@muammar Thank you very rapid response. By the way, can I one window screen such method(not whole screen)? I want to cast game window only. Thanks.
I tested your information. But can't do that. The result is that casted TV was shown 'Default Media Receiver' 'Mkcchromecast v0.3.8.1' only. Doesn't show up image and sound. My environment is Linux Mint 19 (Ubuntu 18.04 LTS based) and installed at
$ dpkg -l | grep mkchromecast
ii mkchromecast 0.3.8.1-1 all Cast your Linux audio or video to your Google Cast devices
ii mkchromecast-alsa 0.3.8.1-1 all ALSA dependencies to cast with mkchromecast
ii mkchromecast-gstreamer 0.3.8.1-1 all GStreamer dependencies to cast with mkchromecast
ii mkchromecast-pulseaudio 0.3.8.1-1 all Pulseaudio dependencies to cast with mkchromecast
Is this bug?

There’s no audio at all and pavucontrol doesn’t provide any option to switch it on. OS is Debian buster, let me know if you need any additional informations.

So when I use just mkchromecast it cast audio but when I do mkchromecast --video --screencast then I get only video :( In second case no sink is created.
Hi Muammar! I try to use mkchromecast from KODI addon to cast videos to my TV. I have both an Chromecast Audio and a Chromecast Video. When mkchromecast starts it will just cast to the first Chromecast device which is always the Audio device in my case. If I use the s option, I will be asked to input the device I want to cast to - that works fine, but from the KODI addon it is not so easy to handle this extra input mkchromecast -s
If I could use an option like -s0, -s1 or something else to select the actual casting device it would be easy to control from the KODI addon.
Or is there a way to set the device number on the chromecast device?
Regards Hans
Did anyone manage to find a way to cast both screen and audio at the same time to the same Chromecast device?
For me mkchromecast --video --screencast just works given that my screen resolution is 1920x1080 and not any lower (my old craptop has a 768p native resolution and requires scaling to get a 1080p desktop). Though due to my own audio device configuration the newly created mkchromecast sink is not selected automatically as the default sink and thus has to be manually selected. I could set the mkchromecast sink as default and get all of the audio there by default too.
