Questions regarding IMX6 Multimedia Framework

Hello,

I have the following questions regarding IMX6 capabilities:

In the TRM, what is meant by “60 fps in unit test without multimedia framework”?
What is that multimedia framework referred to? Specs I found were a few years old. Cannot see to find anything newer.

3. From the TRM we know that the iMX6 is capable of doing 1080p60 (max 240Mpixels/s) especially for 1 cycle/pixel mode. That would be 16bit RG565 which is acceptable for us. That’s a 168Mpixels/s. Can the iMX6 indeed support uncompressed RGB565 video 1080p60 in from MIPI to HDMI output? No codec involved. I am asking since we are struggling to achieve that frame rate. We seem to be blocked around ~50fps…

4. I found this link here doing some research that seem to indicate 1080p60 is doable: https://developer.ridgerun.com/wiki/index.php/Toshiba_TC358743_Linux_driver_for_iMX6

5. I also found this link about using the right Gstreamer plugins to achieve full 60fps https://developer.ridgerun.com/wiki/index.php/Toshiba_TC358743_Linux_driver_for_iMX6

Last time was the big EIM bus inquiry which ended up being a big letdown for us, now we are seeking a plain confirmation that iMX6 can pass through uncompressed 1080p60 from MIPI IN to HDMI out…

In advance, thank you for your help.

Hi Enrique

1.2. "without multimedia framework” means not using video player or other high level

application.

3. from i.MX6DQ RM (for performance of MIPI-CSI2 interface):

The maximum bandwidth of the interface is as follows:

• 200Mhz for 4 data lanes configuration (800Mbps/lane, 400MByte/sec)

for your case, as "16bit RG565 which is acceptable for us. That’s a 168Mpixels/s."

seems this is sufficient.

HDMI is able 1080p60, using kernel parameter video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24

Best regards

igor
