Basically the docs directory is all there is. In practice the only
utilities that are commonly used as ivtvctl, ivtv-tune and ivtv-radio.
The -h option basically gives you the documentation. The cx25840ctl and
ivtvfbctl can be used to control the cx25840 A/V digitizer and the
frame buffer device for a PVR350. Both are rarely used. The other tools
are more example code then anything useful. I've used ivtv-mpegindex.c
on occasion as it is a simple template source to parse an mpeg stream.
I don't mind if someone makes wiki pages for these utilities, I
definitately don't have the time for it.
With respect to the stream types: these are the available types:
0=Program stream
1=Transport stream
2=MPEG1 stream
3=PES A/V stream
5=PES Video stream
7=PES Audio stream
10=DVD stream
11=VCD stream
12=SVCD stream
13=DVD_S1 stream
14=DVD_S2 stream
Currently this is documented in fw-encoder-api.txt, not exactly the most
obvious place. Volunteers?
