Hi,
I know this is a linux1394 issue, but I posted to the mailing list and
have gotten no response. I was wondering if anyone here has seen this
problem and maybe can help me out. TIA. Here's my email to linux1394:
I'm trying to setup a MythTV to record from my Motorola DCT 6412. I
have read through all the documentation and the emails on the various
lists. I am seeing some of the same problems as others, but the
work-around isn't working for me. They say to use plugctl to setup a
broadcast connection and use broadcast within mythtv. I have not been
able to receive video through broadcast.
Basically, I can setup a p2p connection and use test-mpeg to download
video. It works some of the time. The mailing lists say about 50%.
I'm seeing about 33%, but I think that's a quibble and not really
significant.
But, I can't for the life of me get broadcast connections working.
I have a Texas Instruments firewire card. I used it in another computer
to download video from a Sony TRV-120 video camera with Kino. Made some
really cute videos of my kids :) So, I know the card works. Here's the
lspci:
00:08.0 FireWire (IEEE 1394): Texas Instruments TSB12LV26 IEEE-1394
Controller (Link)
I have a Motorola DCT 6412 connected via firewire to the host computer.
Here's plugreport:
Host Adapter 0
==============
Node 0 GUID 0x00309526b0022369
------------------------------
libiec61883 error: error reading oMPR
libiec61883 error: error reading iMPR
Node 1 GUID 0x00152ffffed1547e
------------------------------
oMPR n_plugs=1, data_rate=2, bcast_channel=63
oPCR[0] online=1, bcast_connection=0, n_p2p_connections=2
channel=0, data_rate=2, overhead_id=0, payload=376
iMPR n_plugs=0, data_rate=2
Here's the output from test-mpeg with a p2p connection:
# test-mpeg2 -r 1 foo.ts
libiec61883 warning: Overlayed connection on channel 0.
You may need to manually set the channel on the receiving node.
Starting to receive
done.
# ls -l foo.ts
-rw-r--r-- 1 root root 1136460 Nov 28 12:33 foo.ts
As I said, this works about 1/3 of the time. Playing it with mplayer
works fine, every time I get any video at all. I never get corrupted
video. It's either works or doesn't work.
I haven't been able to find out for sure how to use test-mpeg with a
bcast connection. I think I just supply a bad node. Like so:
# plugctl -p 0 -n 1 oPCR\[0\].channel=63
# plugctl -p 0 -n 1 oPCR\[0\].bcast_connection=1
# test-mpeg2 -r boogabooga foo.ts
libiec61883 warning: No plugs exist on either node; using default
broadcast channel 63.
Starting to receive
done.
# ls -l foo.ts
-rw-r--r-- 1 root root 0 Nov 28 12:36 foo.ts
Now, to get MythTV to work, everyone says to use a bcast connection.
Can someone tell me how to get the bcast connection working? Am I doing
something wrong? Is my test-mpeg run correct? Is my 1394 card hosed?
Thanks,
Dave
