How to display CSI-captured video on MIPI LCD & HDMI at the same time

[ottob]

Hi There,

We are using the 3.10.17 Yocto release for our iMX6. Capturing video over the parallel CSI port and displaying it on a MIPI LCD or HDMI works fine, however not at the same time.

//MIPI LCD Output

gst-launch tvsrc !  mfw_v4lsink

//HDMI Output

gst-launch tvsrc !  mfw_v4lsink device=/dev/video18 disp-width=1920 disp-height=1080

We have tried using "tee" or even modifying the tvsrc driver to allow multiple clients, but the CPU usage goes up to 100% and frames are dropped in HD modes.

This should be a fairly common scenario so I'm suspecting we are doing something wrong. Any ideas on how this can be accomplished ?

Later we need to feed the CSI video to the encoder as well as the LCD & HDMI

Any help is appreciated

Hello,

   Please try using mfw_v4isink instead of mfw_v4lsink.

Please refer to documentation about details.

Have a great day,
Yuri
