• Ffmpeg
• UseUrlProtocol

If you want to use an url protocol to output your encoded media (e.g. tcp://hostname:port) follow these instructions:

• open your favourite media format as you would open it with a file:

AVOutputformat *aof = guess_format ("avi", NULL, NULL);

• Use url_open () instead of url_fopen () and pass it an URLContext pointer and your url :

url_open (url_context, "tcp://hostname:port", URL_WRONLY);

• Use url_open_dyn_buf on ByteIOContext of your AVFormatContext

        url_open_dyn_buf (&format_context -> pb)

• Write your header:

        av_write_header( ... )

• Send it to your url:

guchar *pb_buffer;
int len = url_close_dyn_buf(format_context -> pb, (unsigned char **)(&pb_buffer));
url_write (url_context, (guchar *)pb_buffer, len);

Do the same with av_write_frame:

• Use url_open_dyn_buf() on ByteIOContext of your AVFormatContext

        url_open_dyn_buf (&format_context -> pb)

• write your header:

        av_write_frame( ... )

• Send it to your url:

guchar *pb_buffer;
int len = url_close_dyn_buf(format_context -> pb, (unsigned char **)(&pb_buffer));
url_write (url_context, (guchar *)pb_buffer, len);
