Francois Oligny-Lemieux	ac658be5db	harden h264 decoding to prevent some crashes when input data is corrupted. Patch by Frank %eucloid A gmail P com% date: Jan 18, 2007 6:48 PM subject: Re: [Ffmpeg-devel] h264, protection against corrupted data (second try patch) AND date: Jan 17, 2007 8:22 PM subject: [Ffmpeg-devel] h264, protection against corrupted data this also fixes a possible security issue (the sps and pps ids where not checked, then used as index into an array of sps/pps structs which was then filled with data from the bitstream) Originally committed as revision 7585 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Reimar Döffinger	b18e5c031c	Avoid calling decode_slice when context_initialized is not set. Avoids a crash due to dsp.clear_blocks being NULL when called. Originally committed as revision 7547 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	aa1da263aa	1 variable less in decode_cabac_residual() no speed change (but less vars means less things gcc can load and store redundantly) Originally committed as revision 6734 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	ebd624b662	optimize sign decoding code in decode_residual() x86 is 4% faster on P3 C sign stuff + x86 code for everything else is also faster then before (sorry forgot to test pure C) ... and if i replace the second occurance of the sign decoding in decode_residual by the asm too then everything gets slower iam starting to think that it might be best to write the whole function in asm, playing this avoid random deoptimizations game with gcc is not fun at all Originally committed as revision 6732 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	30865e2aa1	copy cabac context onto the stack for the c code in decode_cabac_residual() (15% faster on P3 but still slower then the current asm) Originally committed as revision 6725 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
