hi TI-friends,

rdk 3.0 ,

we test  16 channel decoding with following pattern, currently it's 15 ch

640x480     x 2 ch

720x480     x 7 ch

1920x1080  x 6 ch

and everything is fine...

and now, we add 1 ch 1920x1080 then the log show

[m3video] DECLINK_H264:HEAPID:0 USED:2368

I have tested each BS independently and saw nothing error.

Any further idea for this?

    Check same configuration with DVRRDK 4.01 decode display demo. RDK 3.0 is not supported

    hello badri,

    thanks for your reply.

    I already use codec from rdk4.01

    I found something strange. The bit-stream has random I-frame interval.

    > I found TI can decode this kind of BS independently.

    Does TI can decode this BS normally?? 

    > And it looks like something crash if I give it too much this kind of BS...

    Any idea?

    There is no issue with streams that don't have random I-frame interval.

    We have tested DVRRDK 4.01 with upto 36 channels 1080P streams and there is no issue.

    after checking, we got the same problem as using RDK 4.1.

    Share the mcfw cmd line demo (SD/HD decode display demo option) log from ./load.sh to when exception occurs.
