imxg2dcompositor|imxipucompositor not support appsrc?

adorable — Fri, 29 Jan 2021 03:50:46 GMT

I want to use appsrc|appsink to push frame-data to imxg2dcompositor or imxipucompositor,but I found the compositor not support appsrc, the error is :internel data streamer err in appsrc.

If I want to use appsink|appsrc to video-compositor,how should I do?

kernel 4.9.88 Imx6q gstreamer1.12.2

phy continues and count not user appsink to push data to appsrc.

Finally I modifyed imxipuvideotransform to modify frame-buffer ,and successed to compositor video0 and video1.video0 is parsed as RGBA,video1 is parsed as I420.
