Function mp4parse_capi::mp4parse_get_pssh_info

#[no_mangle]
pub unsafe extern "C" fn mp4parse_get_pssh_info(
    parser: *mut Mp4parseParser, 
    info: *mut Mp4parsePsshInfo
) -> Mp4parseStatus

Get ‘pssh’ system id and ‘pssh’ box content for eme playback.

The data format of the info struct passed to gecko is:

• system id (16 byte uuid)
• pssh box size (32-bit native endian)
• pssh box content (including header)

Safety

This function is unsafe because it dereferences the the parser and info raw pointers passed to it. Callers should ensure the parser pointer points to a valid Mp4parseParser and that the fragmented pointer points to a valid Mp4parsePsshInfo.
