Hello,
I am just learning how to create programs with ffmpeg.
I wanted to send a video using UDP in a peer to peer
application.
In my understanding in order to be able to send a
video through UDP I requiere the RTP protocol. Then,
following a previous discussion e-mail in this list I
read:
"Streaming over RTP is just like writing to a file:
you just need to use
the rtp format, and to provide an "rtp://<destination
address>:<destination port>" url as output file name."
....
"Just change the file to an RTP url, and you
are done."
So I tried to follow the advice and I wrote the next
code in the next application:
ctx = av_alloc_format_context();
if (!ctx) {
printf("I couldn't allocated the format
context\n");
return;
}
if( url_open(&h, "udp://127.0.0.1:6000",
URL_WRONLY) < 0 ) {
printf("Something wrong with url_open\n");
if (h)
url_close(h);
av_free(ctx);
return;
}
/* f = fopen(filename, "wb");
if (!f) {
fprintf(stderr, "could not open %s\n",
filename);
exit(1);
}
*/
The problem is that the application breaks always on
the url_open function.
Thank you.
Miguel Miranda.
