Streaming to WMP: main private warning: late buffer for mux

[pianoguy]

I'd like to stream from a DVB-T card to Windows Media Player
Thats what i do:

Code: Select all

vlc -vvv dvb-t:adapter=0:frequency=482000000:bandwidth=8 --sout '#transcode{vcodec=DIV3,vb=2048,scale=1,acodec=mp3,ab=128,channels=2}:standard{access=mmsh,mux=asfh,url=172.23.23.103:8080}'

like the documentation says here http://www.videolan.org/doc/streaming-h ... l#id294900

WMP receives the stream, but buffers every few seconds again. The picture hangs.

Thats the server-side output

Code: Select all

[00000260] stream_out_transcode private debug: late picture skipped (8549) [00000269] main private warning: late buffer for mux input (21314) [00000269] main private warning: late buffer for mux input (27389) [00000269] main private warning: late buffer for mux input (5252) [00000260] stream_out_transcode private debug: late picture skipped (13190) [00000269] main private warning: late buffer for mux input (16273) [00000260] stream_out_transcode private debug: late picture skipped (202)

Again and again. A lot of them.

While transcoding the CPU load is nearly 100%. Its a Dual Xeon Machine, so thats very strange. My Network is 100MBit full duplex.

Has somebody successfuly streamed to WMP with the VLC?

Thanks for your help.

I have sent live streams captured by VLC to WMP.
I have done this completely under windows.
I have used MMSH and DIV3 the same as you.
I did not use a dual xeon compute just a simple p4 and every thing was ok.
Just I think, did you decrease the bandwidth? I mean, it seams that the bit rate for your stream is 2MBits, decrease it to 256k.

Thank you for your answer.

Decreasing the bandwidth does not help. I set it to 256Kbits - CPU load at 99% and the same strange output from VLC.
It must be something in general ... like an installation mistake.

The reason for me to do this with Linux/Gentoo is simple: one day i need to livestream 4 channels and 4 DVB cards and Windows do not like each other

[pianoguy]

How do you do this with Windows? I thought the Windows version of VLC doesnt support DVB at all, like its said here http://www.videolan.org/vlc/features.html

@__mami: could also be a cam livestream.

@all: I've isolated my Problem:
regardless which codec i use in the vcodec term, except div3, causes the same effect ... mp1v, mp4v, wmv1, wmv2, mjpg.

Thats the output for mp4v. CPU load is at 99%.
Are there any codecs missing?

I'm using Gentoo with 2.6.15 Kernel and installed the win32codec.
