I'm testing a new way of processing the #DEFCON (And later #InfoCon) videos, can some people help test?

Check out the DEF CON 31 videos and village videos and see if they pseudo stream in your browser of choice.

Download a video or two and see if the subtitle show up in your video player.

The new changes are:
- Now encoded with AV1 instead of HEVC
- Down sampled to 25 frames a second to save on file size
- English subtitles (.srt) are now embedded in the .mp4 file.

All DEF CON video presentations, music, documentaries, pictures, villages, and Capture The Flag data that can be found.

@thedarktangent Windows Media Player needs an AV1 codec to be installed to play the video, and there doesn't seem to be an Opus codec for WMP.
Also, WMP still (despite years of my begging) doesn't support captions in an MP4 stream. Looks like VLC is going to be the way for Windows users to stream this as it's encoded here.

@ftp_alun Does it stream with audio for you in edge? I’ve never tried playing it in windows media player so that is interesting. I saw W11 supposedly supports AV1 natively.

@thedarktangent Either clicking on the link in the folder, or opening the file from a local download, Edge will play the video with its accompanying audio, even before I download the AV1 pack from the Microsoft Store.
It's just WMP that needs the AV1 pack downloaded to do video, and I haven't yet found the magic sauce to make WMP do the audio.
