The VideoLAN Forums

Posted: **13 Feb 2007 22:36**

Most of questions in this forum are not answered. To make this forum more useful, let's share our knowlege here. After long time study, I finnally managed to stream video to Nokia S60 phone (Nokia N95). I tried to stream video from PC to mobile phone and from Dreambox(my satellite receiver) to mobile phone. The video and audio quality is amazingly good.

I don't know how useful this is. Maybe you can watch football matches in your office using your company's WLAN.

To do this, I used VideoLan media player as transcoder and Darwin Stream Server as streaming server. The command line to launch VideoLan is

Code: Select all

call "C:\Program Files\VideoLAN\VLC\vlc.exe" s2.divx :sout=#transcode{vcodec=mp4v,vb=1024,acodec=mp4a,ab=64,channels=2,audio-asyn,width=320,height=240}:rtp{dst=127.0.0.1,port=1234,sdp=file://"C:\Program Files\Darwin Streaming Server\Movies\test.sdp"} --aspect-ratio=width:height

For more details, you may check my website at
http://s60.webhop.org

So far, I haven't been able to stream from pplive(one of p2p TV) to my Dreambox. If you have any hint please let me know. [/url][/code]

hi,

I've been able to stream a video to my n95, but i cannot get sound on it, when i use this command:

Code: Select all

./vlc -I dummy -L file:///home/d2cs/media/in/livebox.flv --sout='#transcode{vcodec=mp4v,vb=1024,acodec=mp3lame,ab=64,channels=2,width=320,height=240}:rtp{dst=172.20.2.181,port=1234,sdp=file:///home/d2cs/media/out/test.sdp}'

I have the following messages:

Code: Select all

VLC media player 0.8.6d Janus
[00000366] dummy interface: using the dummy interface module...
[00000370] stream_out_transcode private error: cannot find encoder ((null))

I have tried with codecs mp4a, mp3, mp3lame, faac, mp2a

any idea ?

Just forgot to mention anything in my previous post, I'm using vlc to stream to darwin which forwards the stream using the appropriate (h264) rtp payload.
VLC creates a sdp file in /usr/local/movies (the default movies location for darwin streaming server on linux):

Code: Select all

v=0
o=- 1205938892850593 1 IN IP4 127.0.0.1
s=NONE
t=0 0
a=tool:vlc 0.8.6a
c=IN IP4 127.0.0.1
m=video 1232 RTP/AVP 96
a=rtpmap:96 MP4V-ES/90000
a=fmtp:96 profile-level-id=3; config=000001b001000001b58913000001000000012000c48d8800cd0a041e1463000001b24c61766330642e35312e31312e30;
b=AS:1024

Darwin streaming server is detecting this sdp file and it is using information available to setup its input using a network stream. Here, 127.0.0.1:1232 is the input stream.

VLC probably calculates the video output stream port using the "port=1234" parameter. In RTP stream, each media stream generally uses an even number because RTCP streams may be sent on the following odd number (1235). But as there is audio and video, I suppose that VLC attributes this port to the audio stream and put the video on a lower port.
When VLC is killed from console (did not test kill -9 $pid), the output file test.sdp is automatically deleted from the file system.

Regarding my previous problem, I modified my input file using ffmpeg to avoid mp3-related issues:

Code: Select all

$ ffmpeg -i in/flv/bourneultimatum.flv -vcodec copy -acodec ac3 out/mpg/bourneultimatum2.mpg

Now when I stream using vlc, I have no error message:

But no test.sdp file is created...

the same command line with -v gave me nothing interesting...

Posted: **19 Mar 2008 16:29**

but the -vv option gave me more details:

and then, many "ps demuxer debug: es id=0xbdXX format unknown"... do you think I should care with those messages ?
should i try with 0.9.0-SVN version ?

Posted: **24 Mar 2008 03:25**

a) What app are your using on your N95 to play the stream?
b) Can you do a multicast (as I've done to other PCs in the building) and just open a network address on the phone?

Cheers, Antony.

a) What app are your using on your N95 to play the stream?

real player, i open rtsp streams using streaming links:

Menu > Media > Gallery > Options > New Link > Phone Memory:

Name: VLC + Darwin
Web address: rtsp://172.20.2.181:5556/test7.sdp

I also tried with the S60 simulator, but I have the same problem.

b) Can you do a multicast

Do you mean I should try something like that:

Code: Select all

./vlc -I dummy -L file:///home/d2cs/media/in/livebox.flv --sout='#transcode{vcodec=mp4v,vb=1024,acodec=mp3lame,ab=64,channels=2,width=320,height=240}:rtp{dst=232.0.1.50,port=1234,sdp=file:///home/d2cs/media/out/test.sdp}'

Here, media packets would be sent via a multicast address between vlc and darwin streaming server, but not between darwin and n95. well, I have to check the generated sdp file...

(as I've done to other PCs in the building)

Sorry, could you give me more details ?

and just open a network address on the phone?

just to confirm: the same rtsp address, not a mulicast rtsp address? because i don't know if it's possible to open rtsp via multicast (rtsp, for rtp we both know that it should be ok)

Posted: **31 Mar 2008 17:10**

oh, finally I fixed it, here is what I have done:
download, configure, compile and install the following libraries with default options:

mp3lame, version 3.97
faac, version 1.26
faad2, version 2.6.1
x264, svn version 2245 (snapshot archive from 2008-03-27)

ffmpeg

download ffmpeg with svn version 12618 (I used the complete svn snapshot archive from 2008-03-28). http://ffmpeg.mplayerhq.hu/download.html
configure ffmpeg with the following options:
Code: Select all
./configure --enable-gpl --enable-pthreads --enable-postproc --enable-libmp3lame --enable-zlib --enable-libmp3lame --enable-libx264 --enable-libfaac --enable-libfaad
build and install ffmpeg

vlc

download vlc source code, version 0.8.6e
install dependencies (with development packages containing headers), for me, the following libraries were lacking:
- libmad...-dev
- libmpeg2...-dev
- libdvbpsi...-dev
configure vlc with the following options:
Code: Select all
./configure --enable-ffmpeg --with-ffmpeg-tree=/usr/local/src/ffmpeg-checkout-2008-03-28/ --with-ffmpeg-mp3lame --with-ffmpeg-zlib --with-ffmpeg-faac --enable-mostly-builtin --enable-dvb --enable-x264 --with-x264-tree=/usr/local/src/x264-snapshot-20080327-2245/ --disable-wxwidgets --disable-skins2 --enable-debug --enable-faad --with-faad-tree=/usr/local/src/faad2/
Of course, this command line must be updated with your actual paths.
build vlc

Then, you have to start darwin streaming server as user qtss:
/usr/local/sbin/DarwinStreamingServer

Now, you can start vlc.
run the following command to stream a video to your loopback address, and specifying an sdp output file to describe the audio and video streams:

Code: Select all

./vlc -I dummy -L /path/to/file/livebox.flv --sout='#transcode{vcodec=mp4v,vb=1024,width=320,height=240,acodec=mp4a}:rtp{dst=127.0.0.1,port=1234,sdp=file:///usr/local/movies/test.sdp}'

Here, /usr/local/movies is important because it is the directory where darwin streaming server is "listening" for new video files.

Now you can use your N95 to open the following streaming link:

rtsp://your.darwin.ip.address:5556/test.sdp

I configured darwin at installation to run on port 5556 on my system to avoid root privileges requirement.

hi, I'm trying the same with a Windows XP as server and a Nokia E51 as client, result:

RealPlayer : connection failed

so I cannot open a stream
is there a link on the web where I can test my nokia settings?

Posted: **03 Apr 2008 13:48**

Can you first try to launch a web server on your xp box and then browse a simple page from your nokia on your web server ?

This is just to validate your wifi connection parameters.
Note that I had to go in menu settings > connectivity > wifi > add a connection manually to connect my n95 on my uncrypted local wifi access point.

But I don't know if Eseries family supports the same RTSP stacks and codecs implementation... Is real player available on your mobile phone ?

Posted: **03 Apr 2008 15:01**

Hi Yohann,

I can browse with my Nokia to a webpage on my XP webserver so the connection is ok

real player is available on my phone Ver: s60.31.33.01 A6 from 13 august 2007

Posted: **10 Apr 2008 11:47**

can you make a network capture between your phone and your computer (with wireshark, for example) ? Thus you could check if rtsp messages are going from darwin streaming server to your mobile phone.

dear wolfx can you pls tell me where i can find a good tutorial how to install vlc on my nokia n95, cannot manage to find a good one !!!:(
thanks in advacne for your help

Dear Wolfx,

I noticed that you're using a video bitrate of 1024kbps (vb=1024). This is too high for 3g cell network (unless you're stringing to your Nokia S60 using WiFi). Do you transcode this down to 200-300kbps somewhere later in your pipeline?

Thanks

Posted: **19 Oct 2009 11:24**

hi,

I was using wifi for video streaming, so I didn't transcode later to lower bitrate.

Hi guys.
I'm trying to stream my webcam to my nokia e65 ( s60 v3 ) via VLC media player.
platform: windows vista

here's the batch script to stream in rtsp

Code: Select all

call "C:\Program Files\VideoLAN\VLC\vlc.exe" dshow://vdev="Chicony USB 2.0 Camera" adev="" -vvv --audio --sout "#transcode:rtp" --sout-rtp-dst="192.168.1.4" --sout-rtp-name="MHSS" --sout-rtp-sdp="rtsp://192.168.1.4:554/webcam.sdp" --sout-transcode-vcodec="mp4v" --sout-transcode-vb="400" --sout-transcode-width="144" --sout-transcode-height="176" --sout-transcode-fps="15" --sout-transcode-aenc="ffmpeg" --sout-transcode-acodec="mp4a" --sout-rtp-mp4a-latm --sout-transcode-ab="32" --sout-transcode-samplerate="16000" --sout-transcode-channels="2"

the thing is, I can recieve this rtsp stream with quicktime player on windows, but I cannot reach it by my cell phone

anyone has any idea why it doesn't work ?

Posted: **26 Nov 2009 12:17**

Why don't you try 1AVStreamer? It will do the same as VLC but without the hassle. All you have to do is copy and paste the broadcast URL, or have it e-mailed to you.

Posted: **26 Nov 2009 14:55**

because I'm doing my final year project at university, an academic work, and as a student I have to implement this kind of project, not spend money on some already implemented kind of project like this.

Posted: **26 Nov 2009 18:36**

Oh, I see. Good luck with your project.

Posted: **19 Apr 2011 19:18**

How's the project coming along?

Posted: **19 Apr 2011 20:45**

Project had been finished 1,5 year ago. I succeeded at it.
