I recently picked up a Canon HV20 the other day. After being annoyed
at iMovie HD transcoding it to another format (11MB/sec instead of
25Mbit/sec), I tried out FreeBSD-current (from a few months ago) and
it works like a charm. A straight fwcontrol -R <file> returned:
fwcontrol: Unsupported format for receiving: fmt=0x25
but forcing it to mpeg w/ -M worked great. Does anyone have tools to
extract the other information that's in the stream?
-bash-2.05b$ ~/p4/bktrauinfo/mpegts.py -b /b/work/foobar.dv

{129: <PMT: {5: ['TSHV\xff\x10\x00\xff\xff\xff\xff']}, ES: [(2, 2064, {}), (3, 2068, {}), (160, 2069, {}), (161, 2065, {})]>, 31: <PMT: {}, ES: []>}
The two "unaccounted" for streams are 30 and 308. Anyone know anything
about these?
Does anyone have any tools for splitting the stream into clips by time
stamp or anything else like that?
P.S. the mpegts.py tool is located in the FreeBSD Perforce repository at:
//depot/user/jmg/bktrau/info/mpegts.py
