Comment:
Did you compare the input and output file? I definitely see the difference
between them. Please, try to watch them again, for example, in QuickTime
or Windows Media Player. Did you look through the attached log? There are
command line and uncut console output. And you might see something like
that "[h264 @ 05ccd4e0] no picture ooo" there.
I think, the problem is in frames' order. Specified line comes from
\libavcodec\h264.c
{{{
if (!out_of_order && pics > h->avctx->has_b_frames) {
h->next_output_pic = out;
if (out_idx == 0 && h->delayed_pic[0] &&
(h->delayed_pic[0]->f->key_frame || h->delayed_pic[0]->mmco_reset)) {
h->next_outputed_poc = INT_MIN;
} else
h->next_outputed_poc = out->poc;
} else {
av_log(h->avctx, AV_LOG_DEBUG, "no picture %s\n", out_of_order ?
"ooo" : "");
}
}}}
