[FFmpeg-user] baseline profile not getting activated in ffmpeg

[Susheel Tickoo]

Hi Carl,
now i have removed the duplicate fields and here are my new settings:

c->width = width;
 c->height = height;
 c->time_base= (AVRational){1,0};
 c->gop_size = 12; // emit one intra frame every ten frames
 c->pix_fmt = PIX_FMT_YUV420P;
 c->codec_type = AVMEDIA_TYPE_VIDEO;
 c->codec_id = codec->id;
 c->max_b_frames = 0;
 c->profile = FF_PROFILE_H264_CONSTRAINED_BASELINE;
 c->me_range = 16;
 c->max_qdiff = 4;
 c->qmin = 10;
 c->qcompress = 0.6;
 c->trellis=0;
 c->level = 13;
 c->refs = 5;
 c->coder_type = 0;
 c->flags|=CODEC_FLAG_LOOP_FILTER;//new
 c->scenechange_threshold = 40; //new
 c-> rc_buffer_size = 0;
 c->me_method=7;
 c->me_cmp|= 1;
 c->me_subpel_quality = 6;
 c->qmax=51;
 c->keyint_min=25;
 av_opt_set(c->priv_data,"subq","6",0);
 av_opt_set(c->priv_data,"crf","20.0",0);
 av_opt_set(c->priv_data,"weighted_p_pred","0",0);
 av_opt_set(c->priv_data,"vprofile","baseline",0);
 av_opt_set(c->priv_data,"preset","medium",0);
 av_opt_set(c->priv_data,"tune","zerolatency",0);

I am setting max_b_frames=0 and i am also setting "*
av_opt_set(c->priv_data,"vprofile","baseline",0);*"

Do i need to set the *profile* or *vprofile* tag ?
I am confused by the ticket http://ffmpeg.org/trac/ffmpeg/ticket/387
I have created the video using max_b_frames=0 and not setting it at all but
in both cases the video is not baseline.

Should i use only teh following line?
c->profile = FF_PROFILE_H264_CONSTRAINED_BASELINE;

Please help me out.
thanks & regards,
Susheel Tickoo
