>From looking at ffmpeg's latest CVS code, the problematic function
definitions are either wrapped by:
#if defined(CONFIG_MUXERS) || defined(CONFIG_PROTOCOLS)
or are not inside CONFIG_MUXERS at all.
Therefore the problem is caused by gst-ffmpeg including a buggy/outdated
version of ffmpeg, or else by their autoconf stuff.
Since this will eventually be fixed when gstreamer updates or fixes
their copy of ffmpeg, I have made a patch that moves only the missing
symbols outside of the #ifdefs. In addition, since the file that
contains 'mpegts_crc32' is only compiled if CONFIG_ENCODERS is enabled,
I copied the code for that function to mpegts.c, where it is referenced.
