<div style="">If you are using the HTTP Live Streaming that depends on the MPEG-2 Transport Stream, I implemented this on live cameras by gorilla subclassing (Cut-n-paste and modify) the MPEG2TransportStreamFromESSource to a MPEG2TransportStreamFromESSource4iOS
class. I changed the inserting of the PAT and PMT to be relative to a chosen number of keyframes instead of a random time so I could easily segment it on the fly downstream.
<br>
<br>
HLS on ios is extreamly picky about the segment size and what it starts with. While it must have recieved at least once in the past, I start each segment with it and a keyframe to allow connections at any time.<br>

Because you refer to "PAT" and "PMT" information, I assume you're referring to a MPEG-2 *Transport* stream. (There are other kinds of MPEG-2 streams as well.)</div>

</div>
<div><br>
<blockquote type="cite">and then I'm trying to decode the frames with help of FFMPEG. My question is: Is it possible to obtain the PAT and PMT information before I pass the frames to FFMPEG with help of the live555 library, or does the live555 library has
nothing to do with this task and it should be handle by FFMPEG?<br>
</blockquote>

</div>
The latter. When the RTSP/RTP client receives the MPEG Transport Stream data, it doesn't inspect its contents at all. So your decoder will need to do that.<br>
