Good C practices are verbose, and verbosity makes for poor examples.

Yes, the first change is necessary, it is not just good practice. It
would be better like the next ones, with an error message, though. This,
IMHO, is the sweet spot between verbosity and API didactics:
codec = avcodec_find_decoder(AV_CODEC_ID_MP2);
if (!codec) {
fprintf(stderr, "Codec not found\n");
exit(1);
}
If we really want to bring attention to good practices, we can add:
exit(1); /* or proper cleanup and returning */
And in any case, the commit message should inaccurately pretend to fix
possible leaks.
