Details of H.264 encoder support in i.MX8MMini

[ko-hey]

Hi all,

I'm investigating a device spec of H.264 encoder in i.MX8MMini.

Could someone teach me following questions ?

Q1.What GOP structure of H.264 Encoder does i.MX8MMini support ?  

Q2.What is the maximum GOP size of the H.264 Encoder (how long can the GOP be extended)?
Q3.What is the CPB (Coded Picture Buffer) size of the H.264 Encoder?
Q4.What is the output format of H.264 Encoder encoded data?
Q5.What is the supported encoding bit depth of H.264 Encoder?

Hello,

"

Q1.What GOP structure of H.264 Encoder does i.MX8MMini support ? 

[Answer] : gop is used to set interval of I frames

Q2.What is the maximum GOP size of the H.264 Encoder (how long can the GOP be extended)?

[Answer] : [1: 300]

Q3.What is the CPB (Coded Picture Buffer) size of the H.264 Encoder?

[Answer] : it is related with the encoded(compressed) data size, basically, user don’t need to handle it

Q4.What is the output format of H.264 Encoder encoded data?

[Answer] : just encoded(compressed) data, not any special format defined

Q5.What is the supported encoding bit depth of H.264 Encoder

[Answer] : only 8 bit
