Failed to send udp over streaming with encode1080p application Sample

Vincent 51111

Hi Ti,

I was following sample of encode1080p udp streaming. My own video analysis codec was added into codec server.

If I don't specify the videobit rate in command line, only first 2 or 3 frames were sent over udp streaming. all the following were missing. through network analyzer, I found those frames were never sent out.

then I go to arm side, in tsfilewrite_thread at tsfilewrite.c

        retVal = IRIO_acquire(rioHandle, (void*)&acqPtr, &acqSize, &rioAttrPendingFlag);
        
        AVCLOG(AVC_MOD_MAIN, AVC_LVL_TRACE, ("IRIO_acquire(%d,%d) returned %x",
            acqSize,rioAttrPendingFlag,retVal));

after two or three frames, IRIO_acquire always failed. (retVal != AVC_SUCCESS).

if I specify bitrate at 800k, the udp packets were sent out in the first 5 or 6 minutes. During this period, retVal != AVC_SUCCESS happened as well, but not always.

Can someone help explain why this happens?

is this related to buffer setting? if so, how can I adjust it?

or is there any other solution?

thanks.
