21.9 azspeech transcribe video

We can extract the audio from a video with ffmpeg, as in the GNU/Linux Survival Guide:

ffmpeg -i myvid.mp4 myvid.wav

It is then straightforward to transcribe the wav file, saving the output into the text version:

ml transcribe azspeech myvid.wav > myvid.txt

With a pipeline, the current implementation of the transcribe command will not wait for the audio to complete.
