Hi, I need to encode a video from image. I use ffmpeg and compiling rigth. My problem is that when i try to opne video with quicktime on iphone, this give me a message "this movie format is not supported". I create a file mp4 with this parameter on context:

context->time_base.num = 1; context->time_base.den = 15; context->codec_type = CODEC_TYPE_VIDEO; context->codec_id = CODEC_ID_H264; context->bit_rate = 1000000;

context->width = width; context->height = height;

context->keyint_min = 10; context->i_quant_factor = 0.71; context->bit_rate_tolerance = 20000; context->rc_max_rate = 100000; context->rc_buffer_size = 8835000; context->qcompress = 0.6; context->qmin = 10; context->qmax = 30; context->max_qdiff = 4; context->gop_size = 30;

context->time_base.num = 1;

context->time_base.den = 30; context->sample_aspect_ratio = av_d2q(1, 255); context->profile = 30;

context->pix_fmt = PIX_FMT_YUV420P;

context->flags |= CODEC_FLAG_LOOP_FILTER;

where is my mistake?? thanks
