I am trying to extract embedded meta data from imx327 sensor using a gstreamer based app. I use nvgstapps_src.tbz2 from L4T sources as reference . In nvgstcapture-1.0 application I tried enabling --enable-meta and I tried accesing sensor_data from sensor_metadata structure(sensor_metadata->sensor_data).
AuxData *sensor_metadata = NULL;
I believe it is a void pointer, but I get NULL when i try to access it in probe function. Does it contain the embedded metadata ?
Or is there any other ways to access embedded metadata from senor using gstreamer. If not with gstreamer , is there any way to read the same using argus_camera application?
