  • Alpha Passthrough. How does it work?

2 months later

Sandi_SLR A few months later, have you guys checked what's wrong with playing alpha videos via DLNA?
Copying 30-40 GB to my headset is not really a solution or workaround for me, and not something I plan to do often.
What's the point of using DLNA then for these types of videos? From my dev point of view, it shouldn't be difficult to debug.

      Some DLNA servers essentially 'rename' the video went sent over streaming like plex.
      I believe Kodi doesnt so give that one a try

          kudirnad Actually, I'm streaming from Windows 11's built-in DLNA server. I'll give Kodi a try. Haven't used it in years LoL 🙂

            kudirnad I've just tried it with Kodi. Thanks for the suggestion, but it's all the same. I wouldn't say it has anything to do with DLNA itself, but the way DeoVR is handling alpha passthrough streams via DLNA.

              @Sandi_SLR I have file that has "_alpha" in filename and when viewing directly from local Quest 2 storage, the alpha channel works ok. However when I view the file via URL link on NAS (e.g. http://192.168...), there is no (A) button present to enable alpha channel.

              Is there something on my side or it is currently not supported?

                timdey837 That's what I'm also talking about for the whole time. I even somehow got that "A" icon to show up, but enabling and disabling it does literally nothing. From a technical point of view (and being a developer too), I think it's more a case of not taking it as a priority than something that it's very hard or impossible to solve.

                If I may, one of the workarounds could be creating a temporary file on the headset (not necessarily the size of the original file, but only like 1GB for the video buffering), and then streaming the video as if it was actually stored on the headset. That could work because (to spare me some time when copying 30+GB file), I start copying it with my built-in File Manager in the background, and I'm still able to watch the video without any issue whatsoever (but I still have to have 30GB of free space).

                Just my 2 cents. At least check if that's possible. @dev team

                  That's great to hear. I'll be looking forward to that. I'm playing around in Premiere Pro now trying to figure out how to remove the alpha channel from here. My understanding was that it had more to do with how it was packaged for download and didn't look feasible, but maybe I misunderstood that part.

                    The issue with streaming passthrough videos via DLNA is finally fixed! At least on the Pico platform. Thanks to the team behind it..
