2011-08-26doxygen: fix wrong comment syntax, //< vs. ///<Diego Biurrun
2011-07-29lavc: use designated initialisers for all codecs.Anton Khirnov
It's more readable and less prone to breakage.
2011-07-20Remove snow/dwt test programMans Rullgard
This test program so full of programming errors it is impossible to make sense of it. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-07-11Eliminate FF_COMMON_FRAME macro.Diego Biurrun
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.

2011-06-144:4:4 H.264 decoding supportJason Garrett-Glaser
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.
2011-06-14Roll back 4:4:4 H.264 for nowJason Garrett-Glaser
Needs some ARM/PPC asm modifications.

2011-01-26Add 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>
