Simply spawns an avconv process with any parameters and streams the results to you (meta data + conversion progress)

Using this library, would I be able to parse an mkv file and convert this to mp4 at runtime?
When converting pure audio files avconv's progress output looks like this:
size= 9788kB time=411.62 bitrate= 194.8kbits/s
and the findTime-function returns undefined.
Handy for those of us who didn't opt into the avconv fork.
Underlying assumption: the accepted params for the two are close enough that this would be transparent.

Hi there,
I'm currently storing real-time streams to disk with avconv. I require a means to stop/kill an avconv instance.
Is this supported?
I have got
write EPIPE WriteWrap.afterWrite
I don't know why and how to solve this. this is my parameter:
let avconv_params = [
"-i","pipe:0",
"-r","25",
"-ss","1",
"-frames:v","1",
"-f","image2",
"pipe:1",
]
