We are using below pipeline to stream the video , But when we start it that time IDR frame is missed and its showing blank screen until we get the next IDR frame.
In logs we see -

Pipeline used :
pipeline.pipeline = gst_parse_launch (“v4l2src device=/dev/video0 ! video/x-h264, width=1920, height=720, framerate=30/1, stream-format=byte-stream ! h264parse ! omxh264dec ! queue max-size-time=400000000 ! vspfilter devfile-input=/dev/video11 devfile-output=/dev/video12 ! video/x-raw, format="BGRA", width=1920, height=720 ! kmssink driver-name=rcar-du connector-id=60 plane-id=34 sync=true”, &error);
Qusetion is -
- How to monitor if IDR frame is missed ?
- is there any way to monitor the IDR frame for user application side ? becasue atleast if we miss the IDR frame then until we get next IDR frame we can show some message on the screen instead of blank screen.
- is there any way to check for invalid frame ?
