List: linux-video Subject: [video4linux] Broadway Mpeg-1 Capture Card From: Brian Ristuccia <brianr () osiris ! ml ! org> Date: 1998-11-13 17:05:13 It looks like some folks are working on a Linux driver for the Broadway Mpeg-1 Capture Card, but there's no mention of using the Video For Linux API anywhere on their web page. I sent them mail about the project. Hopefully they'll take a look at the v4l API, and we'll avoid having yet another capture card API.

List: linux-video Subject: [video4linux] From: "D. Huseby" <huseby () u ! washington ! edu> Date: 1998-11-13 20:01:36 Hey Eveybody, As you might have seen, there is a new project starting up to support the Broadway(tm) MPEG1 Capture Card. Data Translation, Inc. has release all of their win32 source and the effort to write a driver for Linux has begun. I have been in contact with the guys at Slashdot and they pointed me in your direction. After talking with Alan, the LinuxBroadway team has decided to integrate into the V4L API. The LinuxBroadway driver will be 100% V4L compliant and will be updated as the V4L API standard evolves. We are also working on an X windows equivilent video capture app that will resemble the win32 capture app that Data Translation, Inc. released. Currently the LinuxBroadway project is still looking for volunteers so if you are interested email Dave Huseby (huseby@u.washington.edu). The home page for the LinuxBroadway project can be found at http://students.washington.edu/huseby/index.html The source code that was released by Data Translation, Inc. can be downloaded from the LinuxBroadway site or from http://www.b-way.com Thanks. Dave Huseby LinuxBroadway Coordinator huseby@u.washington.edu

Unless I've really misinterpreted the spec, this includes mpeg compression in both hardware and software. -- Brian Ristuccia brianr@osiris.ml.org bristucc@baynetworks.com bristucc@cs.uml.edu

The Broadway card does compression at the hardware level. You can put it in AVI mode where it gives you an AVI stream or you can put it in MPEG mode and it gives you MPEG1 compressed stream, either way, it still supports overlay mode. Because the hardware does the compression a command line program is probably going to be required to initialize the hardware before any commands that copy the data directly from the device to a file are issued. The command line details haven't even been looked at yet, so any and all comments and ideas will be considered. I'm pretty sure that no knowledge of the MPEG1 codec will be needed to program apps that use the Broadway card as far as I can tell. If you wanna help with the development email me back huseby@u.washington.edu Dave
