TDA2P-ACD: Encoder How to calculate RTP timestamp from H264 encoded nalu data(Frame)

Hi,

I will check with the team & get back to you.

Thanks

Hi Gaviraju

follow up questions:

is nalu data is a just one frame at a time? or it contains multiple frame(is it contains more than one frame)?

I configured camera at 22fps and is the value srctimestamp(bit_stream.payload.srctiemstamp) in capture link for each frame when reach encoderlink does it change to each I/P/B/IDR frame time stamp.My encoder is configured 15fps.How can I use src time stamp to calculate RTP timestamp that required for each frame type?

Does the h264 contains any field of time information that we can use.We need to use timestamp for each frame type(I/P/B/IDR) in RTP field.

Please advise.

Hi 

If you running vision SDK link & chain then Each frames of data will have timestamp information.

Just grep the keyword "srcTimestamp" in vision SDK to know about this.

"srcTimestamp" is the one of the structure member in a system buffer & it's used to hold the timestamp value.

Refer the sync link: vision_sdk/links_fw/src/rtos/links_common/sync/syncLink_tsk.c

Hi Gaviraju,

We are using the srcTimestamp.Can you revisit my previous questions?

Hi,

Can I know your link & chain? (Which is mentioned in the use-case text file).

Thanks
