Recommended Encoding Parameters

The encoding parameters are related to the hardware environment of the video stream cloud phone. For details about the hardware environment, see "Software Deployment" > "Environment Requirements" > "Hardware Environment" in the Video Stream Engine Feature Guide.

Hardware Configuration Scheme 1

Table 1 Encoding parameters in CBR mode

Parameter	Recommended Value
bitrate	8000000
gopsize	60
profile	main

Table 2 Encoding parameters in CAPPED_CRF mode

Parameter	Recommended Value
gopsize	60
profile	main
crf	21
maxCrfRate	10000000
vbvBufferSize	1000

In hardware configuration scheme 1 (W6800 + Quadra), you are advised to use VPU for encoding.

Hardware Configuration Scheme 2

Table 3 Encoding parameters in CBR mode

Parameter	Recommended Value
bitrate	8000000
gopsize	60
profile	main

For hardware configuration scheme 2 (DC1000), you are advised to use GPU for encoding.
