Re: [libdv-dev] dv_decode_full_frame

[salsaman <sal...@gm...>]

OK, thanks. Actually I already figured most of this out while I was waiting
for a reply !

Now I would like to know how to get the audio values (rate, channels, sample
size, signedness and endianness).

Also, does the add_ntsc_setup field do anything (I see that it is ignored in
init, but can be set separately) ? I seem to be able to encode NTSC without
it.

If anyone is interested, the code is here:
http://lives.cvs.sourceforge.net/lives/lives-plugins/plugins/decoders/dv_decoder.c

it could be a useful example of a simple decoder.

Salsaman.
