I think maybe caused by the image or video size. 

Please check it.Thanks.

Please check th idoubs Issue62, have the same problem.

Did breakpoint, I found error buffer value when send blank packet.

I Comment this line in NgnProxyVideoProducer.mm  
//_producer->enc_cb.callback(_producer->enc_cb.callback_data,butter_ptr,buffer_s
ize);
this OK.

We need check it and found the true reason.

Maybe alloc wrong buffer_size .
