Hi, I’m testing the dynamic bitrate feature, which seems to be implemented in the SDK IEP sample.
I created a dynamic bitrate file according to the documentation (<frame #> )
I also set the RCMode to 0 (0x0 = Constant bitrate mode).

I tried using VLC statistics and ffprobe to check the average bitrate produced and expected it to change according to the dynamic bitrate file by I don’t see the file has any effect.

Some questions:

1. Does dynamic bitrate is implemented in DriveOS 6.0.5?
2. If it does implemented, does it work with CBR?
3. Does Nvidia have a tool for analyzing video?

Thanks.
Yoav.

Dear @yoav10 ,

I created a dynamic bitrate file

I assume you have created file in below format
<frame_id> <bitrate_bps> <vbv_buffer_size_bits>

1. Does dynamic bitrate is implemented in DriveOS 6.0.5?

Yes

2. If it does implemented, does it work with CBR?

Yes

3. Does Nvidia have a tool for analyzing video?

No. we use third party tools.

As Vick asked earlier, could you share steps, config files and details on how the issue was encountered.
