Hi community,

 

I have a question about i.MX6 VPU capability.

I want to know the limit performance to encode and decode simltaneously.

According to page 7 of presentation in  Q&A: MX6 VPU H.264 Dual Stream Encode Limits , I think the following performances are limit.

 

[i.MX6SDL]

1080p@30fps decoding + 1080p@24fps encoding (since i.MX6SDL max VPU frequency is up to 328MHz < 350MHz)

720p@30fps 2streams decoding + 720p@24fps 2streams encoding (since i.MX6SDL max VPU frequency is up to 328MHz < 350MHz)

SD@30fps 4streamsd decoding + SD@30fps 4streams encoding

 

[i.MX6DQ]

1080p@30fps decoding + 1080p@30fps encoding

720p@30fps 2streams  decoding + 720p@30fps 2streams  encoding

SD@30fps 4streams  decoding + SD@30fps 4streams  encoding

 

Is my understanding correct?

 

Best Regards,
