Now I tried not to create new files but to make changes right in gstomx_jpegenc.c and gstomx_jpegenc.h So in these files I renamed jpegenc (JPEGENC, JpegEnc and so on) to ffmpegcsc (FFMPEGCSC and so on correspondingly), After that I made the same changes in /omx/<a href="http://gstomx.conf.in">gstomx.conf.in</a>, /omx/gstomx.c, /omx/Makefile.am. After that I receive next message: -------- Failed to load plugin '/home/siber/omx/lib/gstreamer-0.10/libgstomx.so': /home/siber/omx/lib/gstreamer-0.10/libgstomx.so : undefined symbol gst_omx_ffmpegcsc_get_type -------- I don't know what to do. I guess I should correct also the body of gst_omx_ffmpeg_get_type (previously of gst_omx_jpegenc_get_type), but I can't find where is it located. I found only declaration in /omx/gstomx_ffmpegcsc.h and one reference in /omx/gstomx.c. <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.
