I am not an expert here.<div>But I think that the reason is that the sampling rate of audio does not much the frames ideally. I mean the beginning of the audio sample does not much the beginning of the I-frame. Maybe you need to resample the audio? <div class="gmail_quote">2011/5/27 vineeth <<a href="mailto:nvineeth@gmail.com">nvineeth@gmail.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> Hi, I am doing a cut operation on a mpeg-4 file ( with H264 , AAC ) using GES and using smart coding for this and it seems that there is loss of audio in the begining of the cut file. From preliminary analysis it seems that if the file is being cut from X to Y , video frames start from the nearest iframe to X, but however, audio frames are taken at a point after X. Would like to know if anybody has faced this problem and any suggestions in solving this. Thanks. --vineeth _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> -- Your Sincerely Michal Joachimiak </div>
