Hi, all.
I've got output_example.c and add one source code string for encoding to
H264:
+ fmt->video_codec = CODEC_ID_H264;
if (fmt->video_codec != CODEC_ID_NONE) {
video_st = add_video_stream(oc, fmt->video_codec);
}
And receive following error:
[libx264 @ 0x8dbb1c0] broken ffmpeg default settings detected
[libx264 @ 0x8dbb1c0] use an encoding preset (vpre)
So, five minutes of google and solution was found:
if( c->codec_id == CODEC_ID_H264 )
{
c->me_range = 16;
c->max_qdiff = 4;
c->qmin = 10;
c->qmax = 51;
c->qcompress = 0.6;
}
After that sample video was created. So I copy-paste this changes to my
program, but it's not work. I've show diffs between my program and
output_example, fixed them, but nothing change.
If I comment fmt->video_codec = CODEC_ID_H264 for using default flv-codec,
my program work fine.
So, I have any question:
1) last difference: in my program encode and write_frame process occured in
one thread, and main-thread wait for interruption signals. Can it have side
effects for h264?
2) Also I found difference in generated outputs. output_example generate
video with fps 25 and resolutions 640x480. But my program fps 1000 and no
resolution(for h264) and fps 1000 and resolution 640x480(for default
flv-code). How can it helps? Any Idea?
