Hello to all,
I have to build a gateway that receives an MPEG-4 (simple profile)
stream at datarate M and, in realtime, recompress it to obtain an
MPEG-4 stream at a lower datarate O < M.
I have written all software to receive and transmit using RTP and
Transport Stream (mux/demix) but I don't know how to recompress without
passing through the decode-encode chain that is very expensive.
Do you know if there is a way to process an MPEG-4 stream to lower the
resolution and bitrate?
Thank you very much,
