Hi, I try to rescale a video in a playing pipeline with changing the capsfilter caps property. But the buffers still have the old width/height. The pipeline filesource -> decodebin2 -> videoscale -> capsfilter -> fakesink The caps property on the capsfilter element is initially set to "video/x-raw-yuv, width=300, height=300, bpp=24, depth=24" I am listening on the handoff signal from the fakesink and get the right sized buffer (width=300/height=300). Now, if I change the caps property to "video/x-raw-yuv, width=350, height=300, bpp=24, depth=24" Nothing changes, the buffers from the fakesink handoff signal still have the old width/height. Isn't this one purpose of the videoscale and capsfilter element, to scale the video when the capsfilter property changes? I am using an old gstreamer version 0.28 (in Ubuntu 10.04) (The behaviour is different in a more recent version 0.10.32(or 5?) on Ubuntu 11.10, there the pipeline just stops (demuxer cannot negotiate, I did not investigate this further, as I am forced to use the older gstreamer0.10 version)) Is there a more solid way to change videosize dynamically. (I am afraid I have to implement my one fakesink, so I can change the videosize by implementing my own buffer_alloc function.) nicolai
