They use Windows XP, Vista & Windows 7 32 bit drivers. In the case of these Late 2012 Mac Minis however the "one click fix" seems to be part of the cause of these displaced lines.I'm looking for software info on two older USB hardware MPEG-2 encoder models. Oddly enough this issue seems somehow related to the other audio issues and how activating the Dazzle DVC100 "properties" window then closing it activates the audio on a non-MacMini linux computer. This would then require you to restart OBS then disconnect and reconnect the Dazzle DVC 100 while OBS is running.įor the mac mini this appears to be a one disconnect/reconnect fix! If for any reason you need to readjust the properties for the Dazzle DVC the displaced lines may return. If you see these displaced lines that look like videotape drop-outs, then unplug the Dazzle DVC100 from the USB port WHILE LEAVING OBS RUNNINGĪfter a few seconds reconnect the Dazzle DVC and image will soon update without the displaced lines. Maker sure you have set up the Mac Mini Line in as an audio source in File > SettingsĬonnect the audio of the video source to the Mac MIni Line in. In audio mixer, mute the dazzle DVC 100 audio by clicking on speaker icon You will need a stereo mini Audio cable to get a Line in to the Mac Mini's "line in"Ĭonnect the Video source audio to mac Mini Line in, ignoring audio input onĬonnect the Dazzle DVC100 Directly to a Mac Mini USB portĪdd the Dazzle DVC100 as an audio source to the sources. It would be nice if someone else can test and confirm results Ok I have been working with Dazzle DVC100, OBS on LInux running on Mac Mini after having encountered that displaced line bug. I originally suspected this was power noise but think i have now ruled that out. I even tried a powered USB 3.0 hub and can confirm that there is no power feed nor back-feed to the CPU USB (Ammeter shows 0mA) and the noise remains. It is possible there is a setting that is affecting this but in Linux I see no crossbar settings or the like. My point is that if you intend to run this on Mac Mini hardware, or possibly any Mac hardware be advised as this problem may rear its ugly head. These lines can resemble videotape drop-outs.Pulling the USB connector then re-plugging it makes the lines go away however you can no longer have audio and can not use the "one click fix", as it will not give you the audio back! You would need to restart OBS for the one click fix to work then you have the displaced lines again. The bug is that once the audio gets reset in this way with the "one click fix" posted in this thread, (or possibly before), you will see horizontal lines in the capture feed which appear to be lines displaced from the video. We already know this driver works for a few different cards.Īs I have now tested this "one click fix" on multiple configurations I can also say that if you happen to be running Linux Mint, or possibly any distro of Linux on a 2012 Mac Mini, or possibly other Macs, there is a separate bug which rears its ugly head but so far I have only confirmed it on the MacMini Late 2012 both core i5 and core i7 models. If that dev on github states that the driver gets open when the cog is clicked (no visible driver window) then why can the driver not be opened one time momentarily when the app is first launched? THIS WOULD SOLVE THE PROBLEM! This card may not be the only card affected this way either. I am new to OBS but not to linux, nor open source. I worked hard on my small contribution and I know that others will find it useful as many still use their Dazzle DVC100 to capture analog video. Giving to a community that so quickly writes you off is just plain insanity. It was first marked for moderator approval then disappeared entirely Not that different from how this original post disappeared until I complained. like many software devs, just too smug to fix something with a work-around, although it is done all the time in many pieces of software. It seems the Devs are not interested in making a workaround for this quirk, bugfix or new feature that will allow these devices to be better used in OBS Linux but here they have been handed the solution which they promptly rejected on Github at first calling it a calling it a "support request", which proves to me they did not even take the time to read the bug report at first. My results are EXACTLY the same and the "single click fix" works exactly the same. Ok I just tested this same method on Newest version of Linux Mint Mate: linux Mint 21.2 Victoria (base: Ubuntu 22.04 jammy), Kernel: 5.15.0-76-generic x86_64 bits: 64 compiler: gcc v: 11.3.0, OBS 29.1.3
