TDA4VH-Q1: The encoded h265 data only contains sps, vps, pps frames in the header

enguo.shan

Part Number: TDA4VH-Q1

SDK: 8.6

We have a problem now, the encoded h265 data only contains sps, vps, pps frames at the beginning of the file, as shown in the figure below

We want to insert vps sps pps before each IDR frame, how to configure it, I did not find a configurable interface in the driver？

Hi Enguo,

I have set a parameter for the force every IDR fram to include VPS/SPS/PPS but not sure whether it worked. please help use your analysis tool view whether it worked with the following H265 stream

Thanks & Best Regards!

Sorry, I don't know how to convert mp4 to h265 without modification. Can you give me the original h265 file, or teach me how to remove the mp4 container without loss.
My analysis tool can only analyze h265 bare stream

Enguo,

p_param->forced_idr_header_enable=1;

It worked for me after set this value on the LInux driver.

Enguo,

Based on internal analysis on the encoded bit stream, updating this value does in fact add the additional meta data (vps, sps, and pps) before each IDR frame.

Best,

Brandon
