<p class="MsoNormal">I have created an element as a subclass of GstBaseTransform and overriding the transform_inplace callback there. I'm assuming that each input GstBuffer received there is a full frame, and is exactly one frame. It is working for the current
video file (a H264 file) that I'm testing, but is it going to be true in general?<o:p></o:p></p>

<p class="MsoNormal">This is only partially true for H.264 streams with the caps field alignment=au. The special case being interlaced content were the fields are coded seperatly, in that case the AU is a frame or a field.<o:p></o:p></p>
