I just wanted to know the chip capability of imx6q VPU for CBR mode. I have been setting the CBR of 2.5M bits/sec but the vlc shows the bit rate of 4M bits/sec whenever there is a motion.
imxvpuenc_h264 imx vpu imxstreaming imx6qvpucbr imx6quad
refer to the vpu refence manual, The bitrate should be between 0 and 32767.
Hi Joan Xie,
Our problem is : Even though we have set CBR as 2560 kbps our output stream is showing higher bit rate of 4500 - 5000 kbps as read using vlc player. Our understanding was that our output bit rate would not exceed the CBR set (10% tolerance is acceptable) but this was not observed practically as mentioned above.
Could you please tell us how to restrict encoded output bit rate below the CBR set (+/- 10% tolerance)?
Following are the some of the parameters that we have configured
