[vdr] DVBVideoLAN - FAQ
Hi,
added a FAQ regarding DVBVideoLAN to http://pulp.mine.nu/dvbvideolan
Regards
Markus
--------------------------------------------------------------------------------------------------
Q: Which are the requirements?
A: There are several.
First, the linux machine:
- A DVB card
- Linux drivers from www.linuxtv.org
- VDR 0.99 from Klaus Schmidinger
- A kernel with Multicast networking enabled.
Second, the windows machine:
- Lots of MHz. The DirectShow part eats much power. I'm testing with a
P3-750 and
the cpu load is at about 50-80%, depends on the channel. I try to
lower this sometimes.
- A demultiplexer and a mpeg2decoder as a DirectShow filter, which
supports mpeg2
transport streams. You have one, if you can replay a vdr/pva
recording with your
MediaPlayer. If it's not working, dvbpl will not work.
- A videocard with overlay support
- WindowsXP or Windows2000. I don't have any other windows operating
system to test.
Perhaps Windows95/98 work as well, but it's untested
- DirectX8.0a. No other version tested.
Q: The Player asks for a msvcrtd.dll, where do i find it?
A: You can download it from the this site. Copy the dll into your
player-directory.
Q: Which demuxer and decoder for mpeg2 should I use?
A: As far as I know, there are two. Elecard and Ligos. I prefer the one
from Elecard.
www.elecard.com.
Q: How do I apply the patch on VDR?
A: Simply go in your clean VDR-0.99 dir and enter zcat
vdr-0.99-dvbvl...diff.gz | patch -p1
Q: What do I have to do afterwards?
A: First, you have to set the following environment variables:
DVBVL_DEST with the destination ip
DVBVL_PORT with the port
Example for bash:
export DVBVL_DEST="224.0.1.2"
export DVBVL_PORT="5004"
You have to use 224.0.1.2 and 5004 if you want to use the windows
player, because these
settings are hard coded into the source filter. I don't know yet how to
set these values
from outside DirectShow.
Second, setup the route using something like:
/sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
Q: VDR-Crashes!
A: This is a very new project and I'm sure, there are bugs in it. Please
report your problems and
I'll try to fix it.
Q: DVBVideoLAN Player crashes!
A: See the question above.
Q: DVBVideoLAN Player doesn't stop synchronizing.
A: The reception and decoding of the mpeg2stream is very timecritical.
Especially while
identifying the stream there shouldn't be much stream errors. Try
streaming another
channel. Restart the player.
Q: Player is working, but after some time, audio and video are getting out
of sync.
A: Problem is known. As far as I know, this happens after too many stream
errors. You can
check this with the help of dvbrtp.log. Since the decoding of audio and
video are
independent from each other, yet the only solution is to restart the
player.
Q: Which channels cause problems, which are know to work.
A; I didn't check all of them of course. The lower the bitrate the better.
MTV Europe, Viva
are working very well, ARD, ZDF, Sat1, RTL are ok. Pro7 isn't working
at all, don't know
why.
Q: What about the sources?
A: You have the sources for the linux part. For the windows part, I didn't
release them yet.
