av_get_pix_fmt_string(), added to libavutil/pixdesc.h.
Originally committed as revision 25879 to svn://svn.ffmpeg.org/ffmpeg/trunk
API changes, most recent first:
+2010-12-04 - r25879 - lavu 50.34.0 - av_get_pix_fmt_string()
+ Deprecate avcodec_pix_fmt_string() in favor of
+ pixdesc.h/av_get_pix_fmt_string().
+
2010-12-04 - r25878 - lavcore 1.15.0 - av_image_alloc()
Add av_image_alloc() to libavcore/imgutils.h.
