Can only receive RawAACFrame, no video #10

Thank you for this great project!

Describe the bug Cannot receive video frames, only audio.

To Reproduce Steps to reproduce the behavior:

            using (RtspClient client = new RtspClient(new ConnectionParameters(new Uri("rtsp://192.168.1.xxx:yyy/theCorrectUrl"))
            {
                RequiredTracks = RequiredTracks.All,
                RtpTransport = RtpTransportProtocol.TCP
            }))

Expected behavior I expect to see interleaved audio and video frames, but I only see RawAACFrame.

Desktop (please complete the following information):

Additional context VLC correctly plays both AAC audio and H.264 video with the same URL. I will attempt to get the source and debug.

jdluzen commented 5 years ago

It may have something to do with H264Parser._waitForIFrame, it never gets an IntraFrame.

jdluzen commented 5 years ago

After learning tons about H.264, it seems that my particular encoder sequences the nalUnitTypes like so: 787111...7...[111...7]....

@jdluzen

Thank you for your feedback. Is it possible to give me access to such camera ? I want to research.

BogdanovKirill commented 5 years ago

Any news? Reopen if you need.

zhuzwing commented 2 years ago

I also have this problem here. How to solve it?

theateist commented 1 year ago

I also have this problem. Can anyone explain how to solve this?

dagrooms52 commented 10 months ago

Same problem. I can open the RTSP stream in VLC, but only get audio frames using this client library. I can provide the video if needed.
