Intra Frame forcing at H.264 Encoder (DM 365 )

gidi barak

Hello all

 

As I understand  Intra  frame could be in the H.264 Video stream by two options :

1) Inserted by the User in specific location , for example each 30 sec , for video conf application , RTP method .

2) Request by the decoder incase of packet loss , actualy frame loss in the stream .

I have an RTP over UDP application , where I got IDR location in random location in the video scenario . However ,nor option 1 niether option 2 is activated .

So I do not understand why this happend ? Any reason for that ?

BTW , IDR location is every 900 frames , this is the setup , but I saw in my

video analyzer that I got IDR sometimes each 5 frames , 40 frames , 200 frames , different random location !!

The decoder did not ask for I frame since the RTCP did not show request for I frame .Is this test by looking at RTCP signaling is

good to be sure ?

Any advice for analyzing ...I have the wireshark tool .

 

Regards

 

Gidi

    Gidi,

    Dm36x can insert IDR as per the 2 methods said by you. But for both, the application should configure the encoder correctly. From what i could make out, looks like the encoder app is not doing the configuration fine. I suggest you review the encoder app code and make sure that this feature is implemented fine.

    regards
