[FFmpeg-user] Where are the definitions of choose_sample_fmts, choose_sample_rates, choose_channel_layouts?

[JIA Pei]

Hi, Thanks Carl Eugen Hoyos:


I just downloaded ffmpeg source code from http://ffmpeg.org/download.html ,
by using git:
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

Well, I can't see anything related to
choose_sample_fmts()
choose_sample_rates()
choose_channel_layouts()


Lines from 660 to 709 are:

/* end of sub2video hack */

>     const OptionDef *po = options;
>     OptionsContext bak= *o;

>     while (po->name) {

I also checked libav from http://libav.org/download.html , there is no
definition of these 3 functions as well. So, since there are only tens of
lines of these functions in your download, can you please just attached
your definitions of these 3 functions from line 666 to after 680 ???



Thank you very much...


Best Regards
Pei
