I am using av_read_frame to read packets from an RTSP source.
I am currently using a single-threaded approach along the lines of:
while(connected)
{
av_read_frame(context, packet);
if (packet->stream_id == VIDEO)
{
...
decode and display
}
if (packet->stream_id == DATA)
{
...
do some processing on the data (only ever between 30-50 bytes at
a time)
}
}
The problem I am having is that when executed with the "decode and
display" step, I am only receiving video frame packets and no data
packets. When the "decode and display" step is removed the data packets
come through in abundance.
Also, I have tried inserting a delay into the thread that is doing the
above reading to emulate a high CPU load, this is causing the same problem.
I am not interested in synchronizing the data/video, I just want to
display video frames as they arrive.
Can someone offer some assistance please?
Cheers,
Mark.
