cc [ flag...] file... -lcommputil [ library...] #include <sdp.h> sdp_media_t *sdp_find_media(sdp_media_t *media, const char *name);
The sdp_find_media() function searches the media list for the media specified by name. If the media is found it returns the pointer to the media. Otherwise it returns NULL.
The sdp_find_media() function returns the media (sdp_media_t *) on success and NULL when the search fails or the mandatory input parameters are NULL.

* my_media now points to the structure containg video media section
