2011-01-28Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit d36beb3f6902b1217beda576aa18abf7eb72b03c)

2009-04-24Support >8bit per component YUV in FFV1.Michael Niedermayer
decoding becomes slower, encoding becomes faster, with gcc on duron. some inlining overrides like av_flatten are added to keep inlining similar to before. Originally committed as revision 18674 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-24Force speed irrelevant calls to get/put_symbol() to be noinline.Michael Niedermayer
We need to change decode_line to always_inline because gcc decided not to inline it anymore once we force some calls to get/put_symbol() to be non inlined and this decision of gcc would lead to a 10% overall speed loss. 100k smaller object file, no speed change Originally committed as revision 18673 to svn://svn.ffmpeg.org/ffmpeg/trunk
