Hi, I am using following pipeline to send the data: filesrc->rtppay->rtpbin->udpsink At receiver side: udpsrc->rtpbin->depay->decoder->videosink/( filesink location=*.yuv) I am reciveing almost all the data ( 3KB) less on the receiver side(data stored in a file after depay.), but if i take the decoded data in a file(*.yuv) and compare it to the actual size ( filesrc->deoder->filesink location=*.yuv), it is almost 1/5. This problem is coming only in case of *.m4v files.( files those contain only video data.) If i use container format and demuxer there is no data loss. Where am i missing the data ? What can be metter way to get all the data, even if data is not send onper frame basis ? Please help as i am stuck on this problem since last so many days. BR Manish
