'subtype' is not recognized as an internal or external command,
operable program or batch file.
Any correction to what I've specified is welcome. Thanks!
If I had to guess your trying to run a command for a older camera format and I am guessing that your camera is JS and the format your trying is for non JS cameras.. Also not sure that your camera supports ffmpeg
Since the debug log says "subtype" is not recognized as a command what must be happening is that the shell you are executing the command in is interpreting the "&" to run the following text as a separate command asynchronously. This is normal behavior for a shell. Try just putting a backslash before the & to escape this.
Now, the & would not be an issue in VLC's UI and would not need escaping. The syntax in your first example looks good to me for creating a snapshot/jpeg from the first frame of the stream.

Do you have a VLC error log?
The "\" fixed the ffmpeg issue. Original failure in Windows 10 command prompt, haven't actually gotten it to work there, but works fine on debian, vanilla "sh".
The VLC issue was an embarrassing typo/bad cut&paste that I didn't see until the light of a new day.
I personally don't I am sure if there was a command @GaryOkie would be better suited to offer that query. He has more knowing in the CGI. In general for me I have my cameras connected to NVR's and DVR's and don't do much outside the normal FTP or Device Recordings.. Also jack7 might also know the command your looking for as well.
