[android-developers] Re: Playing live stream (RTP) in MediaPlayer
This might not be the right forum for this question, but I am struggling for some days to get the right combination in ffserver.conf Could you please share the ffserver configuration file that you used? I have tried using ffserver on Ubuntu 8.04 and get a sedmentation fault Using ffserver on the adb shell shows following Could not open output feed file '/tmp/feed1.ffm.ffm' error.

It is possible to play a stream by requesting it via a RTSP request (both audio and video are sent over RTP and the MediaPlayer is able to decode and play them). But it is not possible to play live RTP stream by requesting the SDP file directly (via an HTTP request). The RTP streams (audio and video) are sent to the device from the server. The MediaPlayer should just get the SDP file, listen on the proper ports and decode the streams. But it generates an error and do not play the streams.

[android-developers] Re: Playing live stream (RTP) in MediaPlayer
Hi Andy,
Good to see that the problem is not only specific to my environment :)
And I hope we could find a solution, or at least one Android engineer
will take a look at this post.
I still stuck on it... I tried on Android 1.6 (G1) and Android 2.1
(HTC Desire). Both do not work.
I'm currently looking into the MediaPlayer sources, to see if I can
get more details about the error and maybe fix the bug myself.
Cheers

Hi dillirao,
I don't receive onPrepared callback.
After requesting the live stream through the SDP file (http://

- onErrorCallback -- Command PLAYER_INIT completed with an error or
info PVMFErrCorrupt
My file is encoded in MPEG-4 part 2, audio is AAC, file format
is .mp4, resolution is 320x240. I have a bitrate of 700kbps but bw

I can stream the same file with a RTSP request from the Darwin server.
It works smoothly.
Any idea why the device returns this error ? evn though it can play
the same stream via RTSP ?

whats video profile and audio profile you are using.
use : h263/h264 15fps; 176x144 or 320x240 and use low bit rate , on

I broadcast a stream with Darwin streaming server (via
PlaylistBroadcast) to my Android phone. The stream is sent over RTP to
the IP of my device (unicast). A .sdp file describes my stream.
In my app, I try to play the stream with the following code where url

int height=player.getVideoHeight();
if (width!=0 height!=0) {
holder.setFixedSize(width, height);
player.start();
}
}
I always have a black screen, buffering remains at 0%.
I checked that I can play this live stream on VLC and QT on a desktop,
and it works fine. If I request the same file via a direct RTSP
request (rtsp://server_IP/myVideo.mp4) the file plays correctly on my
android phone.
I also tried to request the .sdp file by an HTTP request (http://
server_IP/live.sdp) but the result is the same (black screen).
Does anybody have already succeeded in playing a live stream on an
android phone ?

In the interests of keeping things together here is the
linkhttp://groups.google.com/group/android-developers/browse_thread/thread/f963e8f7ac35b75bfor
my thread I started in the developers thread just a few days ago
related
to this.
I will file a bug request sometime soon unless anybody else can shed any
light (although I don't know if there will be much attention paid to it). It
is more a feature enhancement than a bug I think, but
it's definitely causing me difficulty.
The functionality to decode RTP streams is already built into OpenCore but
unfortunately you can't pass an SDP file to the MediaPlayer (OpenCore
Wrapper) unless it contains an RTSP stream link inside it. This is a bit
dumb really... what's the point in passing an SDP file in that case? but ah.
There seems to be a limitation that means that it will only accept SDP
information with RTP streams inside if it gets them from the RTSP stream
(e.g. it gets this information from SETUP in the RTSP protocal).
Thus far it seems the only solution is to dump the RTP packets to a file
(periodically close the file and write a new one) then periodically open
these files in mediaplayer. A pretty ugly hack really!

RTSP is not a stream. It's a command and control protocol. The SDP
announcement(s)
is the payload describing the media to be streamed. SIP also uses SDP.
The flow is:
RTSP/PLAY-- client
RTSP/SDP - client
RTP--- client
Where you just listen for the UDP RTP packets on the port the SDP
announcement told you listen on.
