# Video encode and decode
Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html)
The camera and video encode use cases show various scenarios for encoding and
processing the live 4K and 1080p camera streams.
Before you begin running the use cases, ensure that you complete the preconditions
mentioned in Run multimedia use cases.
Note: 24 end-to-end concurrent video sessions aren't supported for
QCS6490.
## One stream–1080p AVC RTSP from live source
Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html)
The use case uses a 1080p stream from the camera for encoding. The encoded stream is
sent over the network using the RTSP streaming.

- Run the RTSP server on target with udpsrc (You can run it in the background as a
service):
gst-rtsp-server -p 8900 -a "< IP_address of the device >" -m /live "( udpsrc name=pay0 port=8554 caps=\"application/x-rtp,media=video,clock-rate=90000,encoding-name=H264,payload=96\" )"Copy to clipboard
- Run the pipeline in another console on the
target:

The streamed video is displayed as an RTSP stream on a host.
To stop the use case, use CTRL + C.
### View RTSP stream on host computer
**Prerequisites:**
- Install the VLC media player on the host computer.
- Set the binary/executable paths in the environment variables.
On the Linux host, do one of the following:
- vlc -vvv rtsp://<IP\_address of the device>:8900/live
[Ubuntu 18.04 with VLC version 3.0.8]
- ffplay -rtsp\_transport tcp rtsp://<IP\_address of the
device>:8900/live
On the Windows host, do the following:
1. Open the VLC media player.
2. Go to Media > Open Network Stream, or use CTRL +
N.
3. Enter rtsp://<IP\_address of the device>:8900/live.
4. Select Play.
## Two streams–4K AVC and 480p AVC from live source
Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html)
The use cases use one 4k stream and one 1080p stream from the camera for encoding.
Each encoded stream is multiplexed into a different file.
Run the use case:
gst-launch-1.0 -e qtiqmmfsrc name=camsrc video_0::type=preview ! video/x-raw,format=NV12_Q08C,width=3840,height=2160,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! v4l2h264enc capture-io-mode=4 output-io-mode=5 ! queue ! h264parse ! mp4mux ! queue ! filesink location="/opt/mux1.mp4" camsrc. ! video/x-raw,format=NV12_Q08C,width=640,height=480,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! v4l2h264enc capture-io-mode=4 output-io-mode=5 ! queue ! h264parse ! mp4mux ! queue ! filesink location="/opt/mux2.mp4"Copy to clipboard
To
stop the use case, use CTRL + C. Pull the
recorded content from the device using the following `scp` command and
then play the content on a host PC.
You can play the MP4 file on a media player. Pull the recorded

The MJPEG encoder encodes and writes the captured video stream in an MJPEG format.
Run the use cases for encoding, saving to file, and previewing on display.
Note: For QCS9075 and QCS8275, the MJPEG video encoding is

## Slice-based encoding
Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html)
With slice support for video encoding, the video stream is divided or sliced into
several sections so that you can encode them in parallel.
You can use slice-based encoding for video playback, teleconferencing, and security
camera use cases.
The following commands enable you to implement slice-based encoding on a camera stream.
The output video.mp4 file is stored at
/opt/.

## MJPEG video encode in CPU and GPU
Source: [https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70018-50/topic/camera-and-video-encode.html)
For MJPEG encoding, if the hardware isn't available, support is required for CPU and
GPU. The use cases include the capabilities to encode a 16-channel 1080p@2fps
video.
Note: For QCS9075 and QCS8275, the MJPEG video encoding is
currently not supported.
### Prerequisites
For MJPEG encoding, support
for 1080p@2fps in CPU/GPU is required.
Set the following environment variables before
running the use
cases:
export XDG_RUNTIME_DIR=/dev/socket/westonCopy to clipboard
export WAYLAND_DISPLAY=wayland-1Copy to clipboard
