Problem mms(h)-streaming to Win Media Player AND mplayer

bogogil · Postby **bogogil** » 20 Mar 2007 13:00

Hello

I want to stream my webcam to my webpages.
I use

vlc -I dummy --noaudio v4l:/dev/video0:size=320x240 --sout '#transcode{vcodec=WMV2,vb=256,scale=1}:standard{access=mmsh,mux=avi,url=:8080/stream.avi}'

to start my stream.

But when I try to access it with mplayer:

Code: Select all

mplayer mms://127.0.0.1:8080/stream.avi

mplayer waits forever "connected":

Code: Select all

MPlayer 1.0rc1-4.1.1 (C) 2000-2006 MPlayer Team
CPU: Intel(R) Pentium(R) 4 CPU 1.60GHz (Family: 15, Model: 1, Stepping: 2)

CPUflags:  MMX: 0 MMX2: 0 3DNow: 0 3DNow2: 0 SSE: 0 SSE2: 0

STREAM_ASF, URL: mms://127.0.0.1:8080/stream.asf
Verbinde mit Server 127.0.0.1[127.0.0.1]:8080 ...
Verbunden.

That's it. Nothing else happenes.

vlc starts fine with

Code: Select all

vlc mmsh://127.0.0.1:8080/stream.avi

When I change vlc to use http instead of mmsh, mplayer is able to play the stream. But the Windows Media Player isn't.
I tried many combinations of codecs, containers and access, but could never get to stream to both, linux and windows.

Why doesn't mplayer play my stream?

Regards
Bogo

Don't mux in AVI using VLC, it's broken (and it's also not mean to be used for live streaming). You should use mux=asfh with mmsh streaming.

When I start vlc with

Code: Select all

vlc -vvv -I dummy --noaudio v4l:/dev/video0:size=320x240 --sout '#transcode{vcodec=WMV2,vb=256,scale=1}:standard{access=mmsh,mux=asfh,url=:8080/stream.asf}'

nothing changes. mplayer still stays forever "connected", but doesn't play anything. I cant see filling the buffer neither.

Here my vlc log:

OK... several thing you might want to try:
Use vcodec=DIV3 instead of vcodec=WMV2, it works better.
Try adding :display instead of :standard{...} in the sout chain and check if anything is displayed on the server. If nothing displays, try running it without the --sout part and check if the v4l device can be played back alright in VLC.
Try connecting with VLC and/or Windows Media Player to that stream (to see if it's an MPlayer related issue).

With Windows Media Player and vlc there is no problem at all.
DIV3 didn't make an difference. The device can be played back with :display.

I guess, it is an mplayer issue. As said earlier, when I changed streaming to access=http, mplayer plays the stream just fine. But then the Windows Media Player can't play it...

dionoea · Postby **dionoea** » 21 Mar 2007 19:40

You'll have to ask the MPlayer guys then

bogogil · Postby **bogogil** » 21 Mar 2007 19:45

Even if other mms streams from the net are beeing played well?
Though I did start an thread which isn't unanswered since yesterday.

dionoea · Postby **dionoea** » 21 Mar 2007 19:56

You could also use tcpdump / wireshark (aka ethereal) on the client to compare VLC mms <-> MPlayer packets with Someother mms <-> MPlayer. Once you spot the difference, I guess that it'll be easy to fix VLC or MPlayer (Whichever is wrong).

bogogil · Postby **bogogil** » 21 Mar 2007 20:25

I'd like to try that.
Can you give me a hint, where to look on?
Totally different streams (codecs, video...) must be totally different, except the mms protocol, which I don't know.

dionoea · Postby **dionoea** » 21 Mar 2007 23:29

The contents of the http headers when starting the connection would be the first place to look I guess. Try to see if MPlayer connects successfully or if it fails because VLC isn't replying like the other servers do. (This would be before any audio/video data gets sent)

pastyr · Postby **pastyr** » 08 Apr 2007 01:30

bogogil, have you solved it? I am having exactly the same problem, at least it looks like that: I stream using '#std{access=mmsh,mux=asfh,dst=:4444}' but I am not able to play the video either locally or on different computer in the LAN. It works when using http and MPEG PS though. Mplayer just outputs 'connected' and that's it - however, it is not only Mplayer's problem - even VLC can't play it, here is the VLC output with -v2:

I guess, it is an mplayer issue. As said earlier, when I changed streaming to access=http, mplayer plays the stream just fine. But then the Windows Media Player can't play it...

Hi, any solutions to this problem?

For me, it's the same: with mms, only Windows Media Player can open the stream, and mplayer just waits forever (and says "connected"). Other mms streams are played by mplayer just fine.

That tcpdump isn't really usefull (at least not to me). Easiest might be:
0. Install wireshark.
1. Capture MPlayer connecting to a native Windows Media Server hosted MMS stream.
2. Capture MPlayer connecting to a VLC MMS stream.
3. Compare the two captures and find what VLC's doing which MPlayer doesn't seem to like.
4. Report your findings here.
5. Submit a patch to VLC

<--- this is the best part
