Hi all,
I'm investigating a device spec of H.264 encoder in i.MX8.
 
Could someone teach me following questions ?
 
Q1.What GOP structure of H.264 Encoder does i.MX8 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?

Please find my reply inline with question.

Q1.What GOP structure of H.264 Encoder does i.MX8X support ?

[Manish] It supports programmable GOP structure,  -IB...BPB...BP...
Q2.What is the maximum GOP size of the H.264 Encoder (how long can the GOP be extended)?

[Manish] I have not find definite answer and will update you once i get detail.
Q3.What is the CPB (Coded Picture Buffer) size of the H.264 Encoder?

[Manish] Can you elaborate more on this question? do you want CPB for encoder or decoder?
Q4.What is the output format of H.264 Encoder encoded data?

[Manish] Output format is NV12.  
Q5.What is the supported encoding bit depth of H.264 Encoder?

[Manish] 8 bit.

 

Generic answer for our encoder capabilities is that we support 1080 30 fps 

o Constrained baseline profile (cBP)
o Main Profile (MP)
o High Profile (HP)
