Extract VP9 Video from MPEG-TS private data stream

[CryGuy]

Hi guys,

I've (accidently) muxed a VP9 video stream into a *.TS file using FFmpeg. It gave me the warning
"codec vp9 is muxed as a private data stream and may not be recognized upon reading"

So, but now it's already there inside the .ts file.
Is there a way to "reinterpret" the stream as a VP9 encoded video stream and remux it to e.g. a MKV container?
I am very familiar with FFmpeg, but I failed doing this. Any clue? Thanks!

Does it show up if you drop it into Mkvtoolnix GUI ?

Same thought. Tried that, and it showed up as an audio stream ("E-AC-3" codec).

I was able to extract the stream as "data", but I don't know how to continue from there:

ffmpeg -i input.ts -map 0 -c copy -f data output.bin

Use tsmuxer and see if the vp9 stream is recognized.

Does it show up if you drop it into Mkvtoolnix GUI and then the MKV file into Inviska MKV Extract ? The other approach wold be to use TSDoctor to extract the files.
