Hi, all I want to write a tool to deal with the video. It needs to grab some frames from the video stream and process it then put it back to the stream. How can I grab frame? can I put it back to the stream after processed ? Thanks! Dennis |

u can register a _callback on the handoff signal (if the element emits it), do the processing and continue. attached is an example i had lying around. another option is to write a small plugin that does the task for you. ~sameer On Sunday 28 October 2007 10:26:35 am Lamoda wrote: > Hi, all > I want to write a tool to deal with the video.

Grabbing a frame out of a running video is non-trivial. It is a question that comes up on this mailinglist with regular intervals, and pretty often it leads to frustration since it requires very intricate knowledge about gstreamer to make it work. Search the archives, and you'll see. I have filed an enhancement bug report about it, here: http://bugzilla.gnome.org/show_bug.cgi?id=464630 In the comments to that bug report, Wim has provided a useful link: http://webcvs.freedesktop.org/gstreamer/gst-plugins-base/tests/examples/snapshot/snapshot.c?revision=1.3&view=markup /Fredrik Persson On Sun, 2007-10-28 at 12:56 +0800, Lamoda wrote: > Hi, all > I want to write a tool to deal with the video.
