1 year ago Looks like bad data in the headers, my tools have found the VR180 metadata put in by Vuze VR Studio, but if can't decompress the compressed mesh data. I've not see bad data from Vuze VR Studio but then again I used the Mac version and not very often, I use ffmpeg myself.
Here's a working injected file using my tool

and the youtube upload
You could 'save' the processed file by using a hex editor, look for the text proj it should be in the middle of this grouping if you find more than one svhd proj prhd
There will be other characters around and between that grouping, but they should be there Change a character in proj to something else e.g. prof being careful not to delete or add an extra character. Then it should run through the spatial media editor to add the metadata.

The mp4 file was rendered by Vuze VR Studio 3.4.7387, using with default settings for Youtube: h264 encoder, 1:1 ratio, 3840x3840 resolution. If uploaded directly to Youtube, processing never completes. (file is only 40MiB and <5 seconds)
Does anyone have any suggestions? It would be helpful if anyone could share an example VR180 file which can be successfully processed and uploaded to Youtube.
Thanks
