operating environment:
- imx-yocto-L5.4.47_2.2.0
- imx8QM
I use openCV VideoWriter and it call gstreamer.
This is my implement e.g. and it occured " Error pushing buffer to GStreamer pipeline".
VideoWriter writer;
cmd = "appsrc ! video/x-raw,format=(string)NV12 ! v4l2h264enc ! h264parse ! mp4mux filesink location=test.mp4 sync=false";
writer.open(cmd, 0, 30, cv::Size(camera_width, camera_height));
I think VideoWriter only enable format=(string)BGR.
Is appsrc capable of NV12 input using opencv VideoWriter?
If so, could you please provide an example implementation?
