SK-AM62A-LP: SK-AM62A-LP: Gstreamer command for AM62A34 processor

Jaimin Patel

Part Number: SK-AM62A-LP

Hello Team,

We are going to use AM62A34 processor for camera product and in that, we need below gstreamer command to test video stream with EVM kit.
Can you please help to get below command?

1: Command to record 1920x1080@30 fps mp4 or h264 video.
2: Command to simultaneously video stream 1920x1080p@30 and 640x480p@30 in H264/H265 format up to 20Mbit/s bitrate on tcpserversink.
3: Command to capture the image (jpeg) with 1920x1080@30 fps resolution.
4: Command to capture 1920x1080p@30 RAW video.

Thanks,
Jaimin

Hi Jaimin,

Can you take a look at the below FAQ and the app note that has few examples on what you are asking:

Hello Suren,
Thanks for your response.

I have checked above documents but I didn't find below command:
1: Command to video stream 1920x1080p@30 with 20Mbit/s bitrate on tcpserversink.
2: Command to capture the image (jpeg) with 1920x1080@30 fps resolution.

Can you please suggest command for that ?

Hi Jaimin,

For Bitrate=500kbps for example, the v4l2h264enc extra-controls would be like these below:

VBR: v4l2h264enc extra-controls="controls, video_bitrate=500000, video_bitrate_mode=0, vbv_buffer_size=3000, frame_level_rate_control_enable=1"

CBR: v4l2h264enc extra-controls="controls, video_bitrate=500000, video_bitrate_mode=0, vbv_buffer_size=10, frame_level_rate_control_enable=1"

Please modify the bitrate to 20Mbps in the above extra-controls and using udpsink to stream the encoded stream. Let me know if this helps.

MJPEG Encode on AM62A with IMX219 camera sensor connected:

gst-launch-1.0 -v v4l2src device=/dev/video-rpi-cam0 io-mode=dmabuf-import num-buffers=100 ! \
video/x-bayer, width=1920, height=1080, framerate=60/1, format=rggb10 ! \
