javacv 1.5 how to get pkt_pos

[asd6390708]

I can get pkt_pos value in javaCV 1.4.4, the code like below:

Frame videoFrame = grabber.grabImage(); AVFrame o = (AVFrame) videoFrame.opaque; long position = o.pkt_pos();

but when i upgrade to 1.5 version, o.pkt_pos() return -1
so how can i get pkt_pos, thanks~

I solved this question by myself
you need set FFmpegFrameGrabber imageMode as RAW，and upgrade javaCV version to 1.5.5+ due to #1568
