 |
|
Hi,
i try to stream some DVB-T Channel with Videolan Client 0.8.2 to my network. I succesfully emerged the VLC:
| Code: | [00000000] main root debug: VLC media player - version 0.8.2 Janus - (c) 1996-2005 VideoLAN
[00000000] main root debug: libvlc was configured with ./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --disable-altivec --disable-utf8 --enable-sout --enable-httpd --enable-vlm --enable-gnutls --enable-v4l --enable-cdda --enable-cddax --enable-vcd --enable-vcdx --enable-dvb --enable-pvr --enable-ogg --enable-mkv --enable-flac --enable-vorbis --enable-theora --enable-x11 --enable-xvideo --enable-glx --enable-opengl --enable-freetype --enable-fribidi --enable-dvdread --enable-dvdplay --enable-dvdnav --disable-fb --enable-svgalib --disable-glide --disable-aa --disable-caca --enable-oss --enable-esd --enable-arts --enable-alsa --enable-wxwindows --enable-ncurses --disable-xosd --disable-lirc --disable-joystick --enable-livedotcom --with-livedotcom-tree=/usr/lib/live --enable-mad --enable-faad --enable-a52 --enable-dts --enable-libmpeg2 --disable-ggi --disable-glide --enable-sdl --enable-png --enable-libxml2 --disable-smb --disable-daap --disable-corba --disable-mod --disable-speex --disable-mozilla --disable-pth --disable-portaudio --disable-slp --disable-hal --disable-x264 --disable-skins2 --with-wx-config=gtk2-ansi-release-2.6 --with-wx-config-path=/usr/lib/wx/config --enable-ffmpeg --with-ffmpeg-zlib --with-ffmpeg-mp3lame --build=i686-pc-linux-gnu |
with the USE Flags
| Code: | media-video/vlc dvd ffmpeg mpeg mad wxwindows aac dts a52 ogg flac theora oggvor
bis matroska freetype bidi xv svga gnutls stream vlm httpd cdda vcd cdio live |
I use the integrated DVB-T drivers from Kernel 2.6.15.
I can watch TV when starting vlc like this:
| Code: | | vlc -vvv dvb-t:adapter=0:frequency=538000000:bandwidth=8 --programs=1 |
(Didnt get it to do this in the GUI  )
So everythings fine except streaming ... i tryed the following -simple- command (without any transcoding, just streaming it):
| Code: | | vlc -vvv dvb-t:adapter=0:frequency=538000000:bandwidth=8 --programs=1 --sout '#standard{access=http,mux=ts,url=172.23.23.103:8081}' |
Thats the serverside output:

I really got no clue what happens here. I havent found anything to the libdvbpsi error, not with google and the people from VLC forum can't or won't help with that.
Someone got a working DVB-T stream with VLC?
Thanks for any help.
greets,

Damnit  it works without the programs-parameter ...
| Code: | | vlc -vvv dvb-t:adapter=0:frequency=538000000:bandwidth=8 --sout '#standard{access=http,mux=ts,url=172.23.23.103:8081}' |
Does anybody kwow how to get the stream compatible to Windows Media Player? http or mms doesnt count.
I tryed:
| Code: | vlc -vvv dvb-t:adapter=0:frequency=482000000:bandwidth=8 --sout '#transcode{vcodec=WMV2,acodec=mp3,vb=256,ab=128,channels=2}:standard{access=http,mux=asf,url=172.23.23.103:8081}'
|
and this creates 100% CPU load and alot of "main private warning: late buffer for mux input" in the server debug. And Windows Media Player buffers endless.

Streaming works fine, but i cant get a working stream for Windows Media Player. I tried like it says in the Videolan Streaming Howto
http://www.videolan.org/doc/streaming-howto/en/ch04.html#id294900
with no sucsess. The Video stutters, WMP re-buffers every 30 seconds and i get some strange output in the console. Video bitrate is huge, i know, but network and pc are very well populated. If i try 256K, only the re-buffering-period takes about 60 seconds, the rest is the same.
This must be some general problem with the installation ... in my above posts are infos from VLC build, use flags. etc.
Is there a codec missing? Some missing use-flag? I use 4 DVB-T cards, the Hauppauge Nova-T with Kernel 2.6.15 drivers.
What i do: | Code: |
vlc -vvv dvb-t:adapter=0:frequency=482000000:bandwidth=8 --sout '#transcode{vcodec=DIV3,vb=2048,scale=1,acodec=mp3,ab=128,channels=2}:std{access=mmsh,mux=asfh,url=172.23.23.103:1234}' |
What i get: | Code: |
[00000269] main private warning: late buffer for mux input (102998)
[00000269] main private warning: late buffer for mux input (80961)
[00000269] main private warning: late buffer for mux input (58847)
[00000269] main private warning: late buffer for mux input (36834)
[00000269] main private warning: late buffer for mux input (14797)
[00000260] stream_out_transcode private debug: late picture skipped (49519) |
about 20 times. Its some ffmpeg output, i think
and then | Code: |
[00000269] main private warning: late buffer for mux input (1771747)
[00000269] main private warning: late buffer for mux input (1792151)
[00000269] main private warning: late buffer for mux input (1817274)
[00000269] main private warning: late buffer for mux input (1834278)
[00000269] stream_out_transcode private debug: late picture skipped (8357) |
all the time without break.
Somebody gets a working WMP-stream from DVB-T with VLC?
Help would be great!
