Hi, all: I'm trying to build avconv.c ... However, I can't find a place that defines the following 4 functions:
> choose_pix_fmts() > choose_sample_fmts() > choose_sample_rates() > choose_channel_layouts() The source code of the file avconv.c can be found at http://libav.org/doxygen/master/avconv_8c_source.html What I've tried is: 1) download the source code by git from http://libav.org/download.html 2) do a thorough search, there is only one single place under the entire source code directory. That is, these 4 functions > choose_pix_fmts() > choose_sample_fmts() > choose_sample_rates() > choose_channel_layouts() only exists in avconv.c, there are no definitions for these 4 functions. I'm just wondering, since there are no definitions for these 4 functions, how come the executable avconv can be built by the libav group? And how did u successfully build it?
