Thank you for your answer! I'm using latest svn source code. I call
avcodec_register_all() at the start, here is my code(it works fine with
codecs other than H264):
av_register_all();
filename = "test.mp4";
fmt = guess_format(NULL, filename, NULL);
if (!fmt) {
printf("Could not deduce output format from file extension: using
MPEG.\n");
fmt = guess_format("mpeg", NULL, NULL);
}
if (!fmt) {
fprintf(stderr, "Could not find suitable output format\n");
exit(1);
}
fmt->video_codec = CODEC_ID_H264;
oc = av_alloc_format_context();
if (!oc) {
fprintf(stderr, "Memory error\n");
exit(1);
}
oc->oformat = fmt;
snprintf(oc->filename, sizeof(oc->filename), "%s", filename);
video_st = NULL;
if (fmt->video_codec != CODEC_ID_NONE) {
video_st = add_video_stream(oc, fmt->video_codec);
}
if (av_set_parameters(oc, NULL) < 0) {
fprintf(stderr, "Invalid output format parameters\n");
exit(1);
}
...
What did I miss?
