# Video encode
Source: [https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html)
The camera and video encode use cases demonstrate various scenarios for encoding and
processing live 4K and 1080p camera streams.
Before you begin executing the use cases, ensure that you complete the preconditions
mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70017-50/topic/multimedia-use-cases.html).
## One stream - 1080p AVC RTSP from live source
Source: [https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html)
The pipeline shows one 1080p stream taken from the camera and sent to the encoder.
The encoded stream is sent over the network using the RTSP streaming.

service):

The streamed video is displayed as an RTSP stream on a host.
To stop the use case, press CTRL + C.
### View RTSP stream on host PC
**Prerequisites:**
- Install the VLC media player on the host machine.
- 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 press CTRL +
N.
3. Enter rtsp://<IP\_address of the device>:8900/live.
4. Click Play.

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, the MJPEG video encode is currently not
supported.
The following are the various use cases for this encoder:
- H.264 encode and MJPEG dump to a

## Slice-based encoding

With slice support for video encoding, the video stream is divided or sliced into
multiple separate 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.

## MJPEG video encode in CPU and GPU
Source: [https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html](https://docs.qualcomm.com/doc/80-70017-50/topic/camera-and-video-encode.html)
For MJPEG encoding, if the hardware is not available, support is required for CPU and
GPU. The use cases include the capabilities to encode 16 channel 1080p@2fps
video.
Note: For QCS9075, the MJPEG video encode 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
