Record 4K resolution video with Snapdragon × MIPI camera

Qualcomm's Snapdragon platform is increasingly being considered as the first choice when customers develop products that support high-resolution cameras. Qualcomm also offers multiple high-performance SoC lineups for IoT devices/embedded devices.

This time, we will introduce how to record 4K resolution video from a MIPI camera using GStreamer for Qualcomm® QCS610 SoC, which has received many inquiries.
Note: Qualcomm® QCS610 SoC supports H.264 / H.265(HEVC) codec and supports video capture at 4K UHD@30fps.

GStreamer command example

This is an example command for compressing 4K@30pfs input video from a MIPI camera into H.264 using the hardware encoder built into the SoC and saving the file in MP4 container format. Connect the ADB debug port of Open Kit to aWindows PC,and execute the following commands on the command prompt of the PC. Commands with(Open Kit)at the beginning indicate that the shell has been started.

> adb root > adb shell (Open Kit)# gst-launch-1.0 -e qtiqmmfsrc name=camsrc ! video/x-raw\(memory:GBM\), format=NV12, width=3840, height=2160, framerate=30/1 ! queue ! omxh264enc control-rate=max-bitrate target-bitrate=6000000 interval-intraframes=29 periodicity-idr=1 ! queue ! h264parse ! mp4mux ! queue ! filesink location="/data/mux_4k_avc.mp4"

To stop recording, press Ctrl+C to exit.

A file called mux_4k_avc.mp4 is saved under /data/ on the Open Kit.

This time, I introduced how to record video from a MIPI camera in 4K resolution using GStreamer.There are other GStreamer plug-ins prepared by Qualcomm, so we would like to introduce them as appropriate as reference information in the future.
