Hi,

I've been trying to get the HDMI input working reliably on my RK3288 Reload board and I can receive the HDMI output from a Macbook pro but not from a Chromecast or a STB - these two just mostly show a back screen.

The Chromecast does show the boot logo but then nothing else is displayed after that.

I'm just testing at the moment so I'm just after some details on what the HDMI input is able to accept. Information related to the resolutions and refresh rates would be most helpful.

If you know of any more fully feature test apps that the system's 'HDMI IN' app that may be helpful for testing then please let me know.

Hi

I recently bought a Firefly RK3288 Reload.

I want to develop basically to applications (to use with Ubuntu or Android):
a Video Recorder that records video capture by the RK3288 HDMI Input (up to 1080p60)
a Video Streamer that streams video capture by the RK3288 HDMI Input (up to 1080p60)
My initial tests:
I've tested the original camera app of Android 5.1 and I was able to take photos a 1920x1080i60 from my notebook HDMI Output.
I've tested the original camera app of Android 5.1 and I was able to display a 1920x1080i60 and 1280x720i60 from my notebook HDMI Output.
I've tested the original camera app of Android 5.1 and I was NOT able to take photos a 1920x1080p60 or  1920x1080i60/50 or  from my camera HDMI Output.
I've tested the original camera app of Android 5.1 and I was NOT able to display a  1920x1080p60 or  1920x1080i60/50 from my camera HDMI Output.
My questions:
The HDMI input works in Ubuntu? With VLC or gstreamer for example?
Do you recommend a ubuntu application to capture HDMI Input?
What are the video formats supported by the HDMI Input?
Where I can find a SDK to develop a application for linux/ubuntu?
Where I can find a SDK to develop a application for android?
Best regards,
Reply

Hi
the HDMI INPUT is actully video device such like uvc for linux  ,so you  just need add kernel driver  like our reload board.
and our latest ubuntu 16.04 have supported vpu in VAAPI,,you can find the firmware in our forum.

Hi & thank you for your help.
I don't know which drivers from make menuconfig we need to activate in order to get support on ubuntu to HDMI INPUT.
I test HDMI INPUT on my firefly reload  running android camera and works fine but I can't find any support on ubuntu preload image.
I need to know which devices is necessary activate from make menuconfig in order to compile and install them.
For example is there a support on firefly reload kernel for TC358749 ? Where? We need only a TC driver or need a CSI2 video driver active too?
Thank you again.

In linux it's not a uvc device, drivers for linux still don't exist more than a year after kickstarter campaign.
