I followed this to encode a sequences images to h.264 video.
Here is outputting part of my code:
int srcstride = outwidth*4;
sws_scale(convertCtx, src_data, &srcstride, 0, outheight, pic_in.img.plane, pic_in.img.i_stride);
x264_nal_t* nals;
int i_nals;
int frame_size = x264_encoder_encode(encoder, &nals, &i_nals, &pic_in, &pic_out);
if (frame_size) {
fwrite(nals[0].p_payload, frame_size, 1, fp);
}
This is in a loop to process frames and write them into a file.
Now, I'm trying to stream these encoded frames through RTMP. As I know, the container for the RTMP is FLV. So I used command line as a trial:
ffmpeg -i test.h264 -vcodec copy -f flv rtmp://localhost:1935/hls/test
This one works well as streaming a h.264 encoded video file.
But how can I implement it as C++ code and stream the frames at the same time when they are generated, just like what I did to stream my Facetime camera.
ffmpeg -f avfoundation -pix_fmt uyvy422 -video_size 1280x720 -framerate 30 -i "1:0" -pix_fmt yuv420p -vcodec libx264 -preset veryfast -acodec libvo_aacenc -f flv -framerate 30 rtmp://localhost:1935/hls/test
This may be a common and practical topic. But I'm stuck here for days, really need some relevant exprience. Thank you!
