[Libav-user] Getting older PTS

Wed Apr 30 12:35:22 CEST 2014

I am new to using FFMPEG. 

YES, I am calculating PTS as "frame.pts = packet.pts *_videoTimeBase;". I am not using FFMPEG decoder(using a 3rd party decoder). So i don't have AVFrame. Hence only PTS I have is the one I get from AVPacket. I have printed PTS in the sequence I get packet from (av_read_frame)

Please see the following log:
