The VideoLAN Forums

Guys,
When I try to view content on my JVC HD10U (high def) camera via firewire through VLC (either live feed or from tape), I get a garbled picture in VLC. Playing or streaming files in VLC works just fine, though. I've tried a lot of different things to solve the problem:
- tried the following options in VLC (dshow-caching=1000,cr-average=1000,turned off hardware overlay)
- reinstalling my firewire driver
- reinstalling my capture driver
- tried a different video card. I went from ATI 9800 all in wonder pro to a matrox parhelia..same problem. So it's not the video card drivers.
- updated my directx to 9.0c

Here is what the messages say. The first error seems to be this:
dshow debug: EnumDeviceCaps: trying pin MPEG2TS Out
dshow debug: EnumDeviceCaps: input pin: unknown format (stream ¤©Š)

Can anybody help?

Guys,
I have found a workaround to the above problem. First, I reset the camera's configuration settings. Next, with the camera off, I reboot my machine. Once the computer comes back up, I start the camera in SD mode. SD (Standard Definition) mode is 16x9, 480P. I open this capture device in VLC to make sure the video plays. When the video plays in SD mode, I can then switch the camera to HD mode, 16x9, 720P. VLC shows the new, more detailed image. I exit capture mode and can stream either the SD or HD content to another computer! At HD, this is pretty impressive imagery and the frames don't skip. Of course, you need a Pentium 3.2Ghz w/a gig of PC3200 RAM.

I'd like to stream at least the lower rez SD content over the net, but I haven't figured that out yet.

thanks for a cool product, guys!

You've created a very good and detailed report, but you missed one vital thing, namly the vlc version used. There is a known bug with vlc reading compressed contents with the dshow module in vlc 0.8.1, if that's the version you are using your workaround is kind of ammusing. You should try one of the later nightly builds at download.videolan.org/~videolan

Thanks Sigmund. Sometimes the most basic things get lost in the detail! I am using intermediate build 0.8.2-svn-20050319.

My current state is that I'm able to successfully stream a live image via SD or HD using UDP and MPEG TS encapsulation. That's cool, but my goal is to get a live image to a publicly available webpage using this cam. Obviously, the bandwidth requirements of an HD image would be prohibitive, but I'd like to at least stream lower rez video. I have tried streaming a live image using MMSH with ASF encapsulation at a lower level of resolution (SD/480P mode), but both Windows Media player and VLC choke on the content. In the case of VLC, VLC on the server side sees a new connection being created, both the client and server sit there saying everything is OK is the message window, but I see no data going across the wire. As to Windows Media Player, who cares! It's Microsoft! It's not designed to work right!

In general, though, it seems that UDP streaming works the best with this camera, but there don't seem many methods of integrating a UDP stream into a web page. I will post questions after further research..unless of course, you happen to know off the top of your head!

I will continue to play with this and read more on the site to try to find the best solution.

thanks again,

After a week of reading and tribulation, I've finally had success streaming a live feed using firewire from my HD10U via MMS! My problem was that I was not transcoding the output of the camera. I got a great deal of help from markfm's post over here:
viewtopic.php?t=8317&highlight=

I didn't understand the muxer (ASF) that I should have used for my output method (MMS). Once I knew that only four video format types (MPEG4, DIVX1/2/3, WMV1/2, MJPEG) worked with the muxer (ASF), I then chose the video format type most compatible (WMV1/2) for my intended audience (general public). I also selected MP3 as my audio format.

Along with markfm's great post from above, I read a LOT of posts and used the following documentation to figure this out:
http://www.videolan.org/streaming/features.html

After I got the basics working within my network and played with bitrates for the most efficient stream over my puny cable connection, I was able to setup a webpage that read in the live MMS stream. I then configured my router to allow traffic to the machine hosting the stream. There's a good deal of detail within those last two steps, but email me if you'd like to know more.

Finally, I'd post a link for you guys to see my stream, but for some reason, the stream crapped out and I am at work and can't fix it. I will let everybody know when it's up. Though, a paltry 400Kbps upload limit from Comcast will prohibit a lot of users from connecting.

thanks for listening,
