Hi :)
Why a encoder has been found but I can't open it.But when I change to
other CODEC_ID_ there is no problem.
h264CodecContext->codec_type = AVMEDIA_TYPE_VIDEO;
h264CodecContext->width = width;
h264CodecContext->height = height;
// h264CodecContext->bit_rate = 400000;
h264CodecContext->time_base = (AVRational) {1,25};
// h264CodecContext->gop_size = 12;
// h264CodecContext->max_b_frames=1;
h264CodecContext->pix_fmt = PIX_FMT_YUV420P;
h264Codec = avcodec_find_encoder(CODEC_ID_MPEG1VIDEO);
if (!h264Codec) {
__android_log_write(ANDROID_LOG_INFO, "NDK", "codec not
found\n");
exit(1);
};
if (avcodec_open(h264CodecContext, h264Codec) < 0) {
__android_log_write(ANDROID_LOG_INFO, "NDK", "OPEN\n");
exit(1);
}
CODEC_ID_MPEG1VIDEO: the avcodec_open worked.
When I changed to MJPEG the avcodec_open failed.
Could you tell me why?
Or where I can find the information to the answer ?
Thanks very much!!
