It is compiled now and my omx_ffmpegcsc is in the plugin list (after gst-inspect). Now I'm stuck with modification gst-openmax wrapper for jpegenc to ffmpegcsc wrapper (wrapper in my mind consists mostly of gstomx_ffmpegcsc.c and gstomx_ffmpegcsc.h files, please correct me if necessary). The biggest problem for me is to change specification of output from JPEG-image to raw-video (YUYV, I420 and so on, like an input data). I've tried something but I'm getting mistake: from element /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: Failed to create output image buffer of 352x288 pixels Pipeline: gst-launch filesrc location=$HOME/GST_OpenMAX/vtest.avi ! avidemux ! omx_mpeg4dec ! omx_ffmpegcsc ! xvimagesink Thank you! <div class="gmail_quote">On Mon, Aug 15, 2011 at 9:39 PM, Felipe Contreras <<a href="mailto:felipe.contreras@gmail.com">felipe.contreras@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div><div></div><div class="h5">On Mon, Aug 15, 2011 at 4:13 PM, Siber <<a href="mailto:tvm.siber@gmail.com">tvm.siber@gmail.com</a>> wrote: > Hello, everybody! > I've just started working with gst-openmax.
