Symptom	Resolution
There may be a timestamping problem, or this computer is too slow.	This message is typically displayed when the GStreamer A/V sync drops some frames. This may be due to a decoder that is too slow, badly timestamped buffers, or a badly formed container (.ts, .3gp, .mp4, .avi, ...). To proceed with investigations, refer to the article How to profile video framerate.

Could not load BMP file	Make sure the loader of the bmp file format, libpixbufloader-bmp.so, is present in /usr/lib/gdk-pixbuf-2.0/2.10.0/. If not, remove /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache, copy libpixbufloader-bmp.so file from distrib build to /usr/lib/gdk-pixbuf-2.0/2.10.0/ then run "/usr/lib/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders > /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders.cache" to reload loaders.
