I have a problem, I try to use  gst-launch-0.10 filesrc location=./1.mp4 ! qtdemux ! omx_mpeg4dec ! ffmpegcolorspace ! videoscale ! ximagesink
to play an mp4 file, but it report errors get_buffer() failed (-1, 0, 0 (nil))   picture size invaild.
I am afraid that omx plugins will not preroll data before playing, so maybe it can not work with other plugins
I want to know if we can use ffmpegcolorspace to connet with omx_mpeg4dec, and is there other omx plugins I can use to play mp4 video.
Thank you very much!
