Streaming mpeg2 without transcoding from PVR150 (0.8.5, Win)

[rasmusb]

I'm trying to stream the mpeg2 that my Hauppauge PVR150 capture to another computer on LAN. I have VLC 0.8.5 and WinXP on both computers.

The captured stream is shown if dshow:// is opened on the capture computer. I'm using the streaming guide in VLC.

First try: source dshow://, method http, package ASF. One or two frames arrive at the streaming client, then everything freezes with loads of asf warnings. I suspect that this line

main debug: using decoder module "rawvideo"

means that the video sent over the network is not actually mpeg2 but rather the raw decoded video stream.

If I try any other container formats I just get this message:

main debug: pre buffering
main debug: prebuffering done 0 bytes in 67s - 0 kbytes/s
main error: cannot pre fill buffer
main warning: cannot create a stream_t from access
main debug: removing module "access_udp"


Is there any way I can make VLC stream the mpeg2 from the capture card?

Best regards,
Rasmus

PVR 150 mpeg2 streaming works fine under linux. I guess that you need to tweak some dshow options to get it to send you encoded video (instead of raw video). If you can't figure that out (i unfortunately doubt that i'll be able to help you ), could you paste the full debug logs from VLC ?

Here is the debug log from the capture computer.

codec=YUV2 -> you're getting raw video from the dshow device. (I really don't know how you can ask it for mpeg2 video instead)

[Quovodis]

the dshow module can process native MPEG2 data from a capture device, unfortunately, in case of the PVR II, the driver do not seem to provide this facility, unless the mysterious HCW2 format contains some sort of MPEG content.
Therefore the dshow module is trying to negotiate with the capture card for a known chroma, and YUY2 is what both ends agreed upon.

[rasmusb]

Thank you for your answers!

I've noticed that MediaPortal (open source) is able to capture mpeg2 from PVR II to file through some kind of filewriter dshow node. Would it be possible to use that knowledge to stream mpeg2 from the card as well or is their solution inherently limited to writing the captured mpeg2 to a file?

Rasmus

Although the VLC doc talks about capture of MPEG2 from WinTV cards being Linux only, I have it happily working on a 1xPVR 250 and 1x350 cards in the same machine. They each stream MPEG2 by default. I think the 150 would work fine too - I was going to get one of these but ended up with the 250/350. I suspect your problem is using ASF to encapsulate - try MPEG TS, no transcoding.

This is one of the command lines:
"C:\Program Files\VideoLAN\VLC\vlc.exe" dshow:// :dshow-vdev="Hauppauge WinTV PVR PCI II Capture" :dshow-size="720x576" :sout=#duplicate{dst=std{access=http,mux=ts,dst=:1234}} --dshow-caching 1000

which works fine streaming http to port 1234. Using two cards is a bit tricky, but I found a post somewhere else which was very helpful. Trust me, this is definitely streaming MPEG2 straight from the card. Uses minimal CPU. I ran the WinTV app to set the input to S-Video first, and set video compression data rates (only needed once), but nothing else was required. This can also be done in graphedit. Linear interlace on the player, great quality. Apologies if I have misunderstood the issue

hello, i have a similar situation. my wintv pvr 150 mce is installed on windows xp home, and works fine in wintv2000 (the hauppage app).

however, when i open the video device in vlc, i select 'Hauppauge WinTV PVR PCI II Capture'. for the audio i select 'default' (the wintv card is not listed? :S)

anyway, it opens the video, and it looks great quality. however the audio does not play, and instead it plays a strange sound that i can only describe as someone running at you.. it gets louder until it turns to static.

the video in VLC appears interlaced wheras in wintv2000 it seems to have been deinterlaced.

ideally i want to be able to stream the output of the tv card to my xbox (running xbmc).

any ideas? do i need a different driver for the card? thanks in advance.

[rggrgg]

If you press 'Refresh List' next to the 'Video Device Name" listbox, the Hauppauge device should appear, and can then be configured. Don't know about your sound problem - I use Svideo-in with Audio into the 'Line-in' of the card, and no need to set up audio device in VLC (I assume the Mpeg stream from the card already contains the audio, since if I refresh the 'Audio Device name', I see no Hauppauge device, only the usual PC sound cards. If you're using the tuner input, you might have to fiddle with something in the 'configure' section next to the video device.

Output will be interlaced - needs to be deinterlaced by the player VLC. Tick the 'deinterlace' box in the Video->Filters section of VLC preferences, and select the type of deinterlace under Video->Filters->Deinterlace. In spite of most people saying'Blend' is best, I find for sport in particular that 'Linear' is by far the best. I don't know what your xbox deinterlace is like, or whether it needs to. (I display using a Hauppauge MVP, and there's no need to deinterlace, since it outputs PAL - gives excellent quality)

[aNthraXx]

thanks for your reply rggrgg.

it seems your card is not the media center edition of the wintv pvr 150, as mine does not have the line in plug, instead it has the red and white composite inputs.

no sound (in vlc) seems to be a reccuring problem with this card, i have seen many posts about it. i was referred to an older driver for the card but this simply stopped the wintv2000 application working and made the picture get worse in vlc with no audio still.

also, when i try to stream the video to my xbox (without sound, just to test), none of the encapsulation methods seem to work. on mpeg ts/ps/1 settings, the xbox caches the stream indefinately without showing the output, and with asf it shows one frame and then crashes. however im using an old version of xbmc, i wil update to 2.00 see if it makes any difference.

i am really stumped by this in the past vlc has always done what i needed effortlessly and it has really annoyed me that this particular function doesnt work, however i do suspect it is mostly the fault of the driver.

i would apprechiate any help from anyone with a similar setup.

thanks , aNthraXx

Hello,

I have the same problem being unable to stream directly from my Hauppauge PVR 150 to the network.
It looks like VLC tries to connect to a wrong output-pin of the "Hauppauge WinTV PVR PCI II Capture" filter called "Capture" (see log "trying pin Capture" ...).
When building a filter graph using graphedit I use the output pin "656" and connect it to a filter called "Hauppauge WinTV PVR PCI II Encoder" which has an input pin called "656" and and MPEG output pin. This works fine in graphedit - I get MPEG video and audio this way.

Is it somehow possible to setup this configuration in VLC ?

Greetings
christian

Any solution for this "no sound" problem?

[asdufisn]

Hello, I'm waiting too for the solution to this problem.
No sound and weird picture quality when streaming from the wintv pvr 150..

Any advice?
Thanks
