mmsh module fails (unsuported while muxing for this format)

[Prutser]

Hi folks,

I'm trying to feed a vanilla WMP from vlc. I've read most of the forum messages on this topic and used MMSH output on vlc with MPEG-TS encapsulation and WMV1/mp3 transcoding.

Problem is, when I press play on vlc, it appears to start playing (I've disabled play-locally), but in the messages pane I see:

main debug: using encoder module "ffmpeg"
stream_out_duplicate debug: duplicated a new stream codec=mpga (es=68 group=1)
main error: cannot add a new stream (unsuported while muxing for this format)
stream_out_duplicate debug: - failed for output 0
main error: cannot create packetizer output
...
main error: cannot add a new stream (unsuported while muxing for this format)
stream_out_duplicate debug: - failed for output 0
stream_out_transcode error: cannot add this stream

It displays the errors in red. Now when I point WMP client (or even vlc) to it, it doesn't work. Looks like the clients never get any input.
I've also fiddled around with different encapsulation (asf, avi) and transcoding (wmv2, div2, div3) in all permutations, but without success. However, when I select plain HTTP as output method it does work (only with a vlc client of course, as vanilla WMP refuses to read from plain http).

Is there something wrong with my vlc installation or is MMSH flawed? Note that I've tried it on Linux (Fedora Core 2) and Win2003. Both give the same error when I select MMSH output.

cheers,
Erik

Hello,

You can't put MP3 in ASF.

Use another codec for audio, like wma (acodec="wma")

[Prutser]

tnx for the quick response. I just tried with all available audio codecs (mpga, mp3, mp4a, a52, vorb, flac and spx) and although I'm unfamiliar with most of them, none of them work. Or rather; vlc still barfs with "cannot add a new stream (unsuported while muxing for this format)".

I also tried with MPEG-TS instead of ASF. No difference.

cheers,
Erik

Quick update.
I've messed around with it a little more and my problem appears to be related to the mpeg file. vlc is incapable of publishing this one mpeg file through mmsh. Regardless of the streaming settings (encapsulation/codec/etc). It does play the file wonderfully, as well as streaming it over http, multicast, etc, but it fails when I select mmsh.
When I loaded a different mpeg file, vlc does work. Strange stuff.. anyone interested in my mpeg file? Or is this a known limitation of any kind?

Next is that I want to run my stream through Windows Media Server. Is there any way I can feed WMS through vlc like a chain? I've tried vlc publishing over http and configuring WMS to source from a "remote publishing point", but wms complains about vlc's stream to be unsupported for no apparent reason. Ironically enough, WMS does not support MMS as a content source..

Anyone ever done this?

cheers,
Erik

Hello friends,
I am also stuck up with the same issue of streaming out from vlc to WMS over RTSP can anyone help me to stream over RTP/RTSP to WMS
