Sorry, but I don't see anything. You might try setting up a different RTSP server (VLC?) and test that for comparison. Capture a wireshark trace to see the detail difference. Also, look up the Android error code -2147483648 to see what it means. <div class="gmail_quote">On Thu, Aug 16, 2012 at 3:05 PM, John Ruemker <<a href="mailto:john.ruemker@gmail.com" target="_blank">john.ruemker@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I've switched to baseline profile and 500Kbps bitrate on x264enc, and scaled the resolution and framerate on videoscale to match the parameters specified in the android requirements, with no change in behavior on the client. gst_rtsp_media_factory_set_launch(factory, "( " "filesrc location=/home/jruemker/Download/star.mkv !

Regarding the app on the android side, I'm using a VideoView element to play. Supposedly you can just hand off the RTSP URI to a VideoView and call the play function and it works. The test I'm using is pretty basic: package org.ruemker.play_rtsp; import android.app.Activity; import android.net.Uri; import android.os.Bundle; import android.widget.MediaController; import android.widget.VideoView; public class MainActivity extends Activity { String SrcPath = "rtsp://<a href="http://192.168.2.9:8554/test" target="_blank">192.168.2.9:8554/test</a>"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); VideoView myVideoView = (VideoView)findViewById(R.id.myvideoview); myVideoView.setVideoURI(Uri.parse(SrcPath)); myVideoView.setMediaController(new MediaController(this)); myVideoView.requestFocus(); myVideoView.start(); } } On 08/16/2012 01:44 PM, Loren Rogers wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Wireshark would help, and you can show "handshaking" RTSP negotiation. What happens in RTSP is a client sends a request which if you look @ the RTSP packets it looks like a URI with a specific format. You'll want to make sure that that URI looks correct and that the android video rendering mechanism is configured to receive that specific media and it's properties. Also I'm not sure about what application you are using on the Android side to request a RTSP session and render the media. But if you are using an app from Google play I'd read up on the help if they have it. Also have a read of RTSP RFC couldn't hurt either. /Loren On Thu, Aug 16, 2012 at 1:37 PM, Chuck Crisler <<a href="mailto:ccrisler@mutualink.net" target="_blank">ccrisler@mutualink.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Sounds like a job for wireshark.

However if I try to switch to ffenc_aac I can't get a stream that even vlc will play. I'm not really sure with rtp payloader goes with ffenc_aac. So ultimately, I decided to just remove the audio stream for now and see if I could get video working. VLC plays it fine, but android still won't, so the issue is likely somewhere in the x264enc part.

I suspect that the defaults are not what the Android wants and probably if any is wrong the Android would reject it but VLC will deal with it. Can you get a log from the Android to see what it doesn't like?
