I believe,i am feeding Quicktime/ISO data to libavcodec for decoding. No i am not using libavformat to demux the file. What i am doing, capturing data using capture card, encoding it using libavcodec and sending it over network using own RTP Stack. Othe node that is also developed by us, is receiving RTP data and feeding it to decoder module (libavcodec) after remving RTP Header (12 Bytes).
PS: Could you please share difference between mov/mp4 file and Quicktime/ISO MPEG4? On 8/9/10, Ronald S.
