Description:
|
Basically, if you have ffmpeg for windows, ex: http://ffmpeg.zeranoe.com/builds
Then run it like this:
enum = `ffmpeg.exe -list_devices true -f dshow -i dummy 2>&1`
"every so often" the value returned is "" (presumably in error).
Example:
39 times you'll get this:
>> enum = `temp
ffmpeg.exe -list_devices true -f dshow -i dummy 2>&1`
=> "ffmpeg version N......\n"
then the 40th (or "xth") will be
>> enum = `temp
ffmpeg.exe -list_devices true -f dshow -i dummy 2>&1`
=> ""
https://gist.github.com/3784971 shows some java code that seems to run it reliably, though I didn't run it under cmd.exe so it's not a 1:1.
