Original commit message from CVS: * ext/ffmpeg/gstffmpegenc.c: (gst_ffmpegenc_connect): Fix pad_link function to handle formats that ffmpeg returns as multiple caps structures. * gst/videofilter/gstvideofilter.c: (gst_videofilter_chain): Only complain if source buffer is _smaller_ than expected. * gst/videoscale/gstvideoscale.c: (gst_videoscale_init), (gst_videoscale_handle_src_event): Resize navigation events when passing them upstream. * gst/videotestsrc/gstvideotestsrc.c: * gst/videotestsrc/gstvideotestsrc.h: * gst/videotestsrc/videotestsrc.c: * gst/videotestsrc/videotestsrc.h: Rewrite many of the buffer painting functions to handle odd sizes (for many formats, size%4!=0 or size%8!=0). Most have been verified to work with my video card. * testsuite/gst-lint: Add check for elements calling gst_pad_get_caps() instead of gst_pad_get_allowed_caps().
