Comment (by andrewrk):
My example was confusing. Let me clarify it to replace "test.flac" with
NULL:
{{{
#include <stdio.h>
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
int main(int argc, char **argv) {
avcodec_register_all();
av_register_all();
AVOutputFormat *oformat = av_guess_format(NULL, "test.ogg", NULL);
enum AVCodecID codec_id = av_guess_codec(oformat, "flac", NULL, NULL,
AVMEDIA_TYPE_AUDIO);
AVCodec *codec = avcodec_find_encoder(codec_id);
fprintf(stderr, "%s\n", codec->name);
return 0;
}
}}}
In this example, we intend to save a file with the file name "test.ogg"
and store FLAC data inside of it. But it prints libvorbis instead of flac.
The format should be ogg and the codec should be flac.
