Tom Marecek	46cbb4c231	ffmpeg: change command line option -dump to work without -loglevel debug -hex and -dump command line options do nothing unless -loglevel debug is set. -dump by itself is useful for monitoring live streams (to get the current PTS for example) however when it is used with -loglevel debug for an RTMP stream, librtmp also dumps the packet data which makes the output too noisy. do_pkt_dump is only set in check_keyboard_interaction or by the -dump command line option so this change should have no effect on any other parts of the code..

Andreas Cadhalpun	fdc94db37e	sbr_qmf_analysis: sanitize input for 32-bit imdct If the input contains too many too large values, the imdct can overflow. Even if it didn't, the output would be larger than the valid range of 29 bits. Note that this is a very delicate limit: Allowing values up to 1<<25 does not prevent input larger than 1<<29 from arriving at sbr_sum_square, while limiting values to 1<<23 breaks the fate-aac-fixed-al_sbr_hq_cm_48_5.1 test.

Ganesh Ajjanagadde	cb93df0dcb	avcodec/aacsbr_tablegen: always initialize tables at runtime This gets rid of virtually useless hardcoded tables hackery. The reason it is useless is that a 320 element lut is anyway placed regardless of --enable-hardcoded-tables, from which all necessary tables are trivially derived at runtime at very low cost: sample benchmark (x86-64, Haswell, GNU/Linux, single run is really what is relevant here since looping drastically changes the bench). Fluctuations are on the order of 10% for the single run test: 39400 decicycles in aacsbr_tableinit, 1 runs, 0 skips 25325 decicycles in aacsbr_tableinit, 2 runs, 0 skips 18475 decicycles in aacsbr_tableinit, 4 runs, 0 skips 15008 decicycles in aacsbr_tableinit, 8 runs, 0 skips 13016 decicycles in aacsbr_tableinit, 16 runs, 0 skips 12005 decicycles in aacsbr_tableinit, 32 runs, 0 skips 11546 decicycles in aacsbr_tableinit, 64 runs, 0 skips 11506 decicycles in aacsbr_tableinit, 128 runs, 0 skips 11500 decicycles in aacsbr_tableinit, 256 runs, 0 skips 11183 decicycles in aacsbr_tableinit, 509 runs, 3 skips Tested with FATE with/without --enable-hardcoded-tables.

Jean Delvare	e74f1a121e	avfilter/vf_delogo: round to the closest value When the interpolated value is divided by the sum of weights, no rounding is done, which means the value is truncated. This results in a slight bias towards dark green in the interpolated area. Rounding properly removes the bias. I measured this change to reduce the interpolation error by 1 to 2 % on average on a number of sample input and logo area combinations.

Ganesh Ajjanagadde	c8905e0d67	swscale/utils: replace pow by exp2 exp2 is a faster function. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago
Ganesh Ajjanagadde	42868ca569	avcodec/jpeg2000: replace naive pow call with smarter exp2fi pow is a very wasteful function for this purpose. A low hanging fruit would be simply to replace with exp2f, and that does yield some speedup. However, there are 2 drawbacks of this: 1. It does not exploit the integer nature of the argument. 2. (minor) Some platforms lack a proper exp2f routine, making benefits available only to non broken libm. 3. exp2f does not solve the same issue that plagues pow, namely terrible worst case performance. This is a fundamental issue known as the "table-maker's dilemma" recognized by Prof. Kahan himself and subsequently elaborated and researched by many others. All this is clear from benchmarks below. This exploits the IEEE-754 format to get very good performance even in the worst case for integer powers of 2. This solves all the issues noted above. Function tested with clang usan over [-1000, 1000] (beyond range of relevance for this, which is [-255, 255]), patch itself with FATE. Benchmarks obtained on x86-64, Haswell, GNU-Linux via 10^5 iterations of the pow call, START/STOP, and command ffplay ~/samples/jpeg2000/chiens_dcinema2K.mxf. Low number of runs also given to prove the point about worst case: pow: 216270 decicycles in pow, 1 runs, 0 skips 110175 decicycles in pow, 2 runs, 0 skips 56085 decicycles in pow, 4 runs, 0 skips 29013 decicycles in pow, 8 runs, 0 skips 15472 decicycles in pow, 16 runs, 0 skips 8689 decicycles in pow, 32 runs, 0 skips 5295 decicycles in pow, 64 runs, 0 skips 3599 decicycles in pow, 128 runs, 0 skips 2748 decicycles in pow, 256 runs, 0 skips 2304 decicycles in pow, 511 runs, 1 skips 2072 decicycles in pow, 1022 runs, 2 skips 1963 decicycles in pow, 2044 runs, 4 skips 1894 decicycles in pow, 4091 runs, 5 skips 1860 decicycles in pow, 8184 runs, 8 skips exp2f: 134140 decicycles in pow, 1 runs, 0 skips 68110 decicycles in pow, 2 runs, 0 skips 34530 decicycles in pow, 4 runs, 0 skips 17677 decicycles in pow, 8 runs, 0 skips 9175 decicycles in pow, 16 runs, 0 skips 4931 decicycles in pow, 32 runs, 0 skips 2808 decicycles in pow, 64 runs, 0 skips 1747 decicycles in pow, 128 runs, 0 skips 1208 decicycles in pow, 256 runs, 0 skips 952 decicycles in pow, 512 runs, 0 skips 822 decicycles in pow, 1024 runs, 0 skips 765 decicycles in pow, 2047 runs, 1 skips 722 decicycles in pow, 4094 runs, 2 skips 693 decicycles in pow, 8190 runs, 2 skips exp2fi: 2740 decicycles in pow, 1 runs, 0 skips 1530 decicycles in pow, 2 runs, 0 skips 955 decicycles in pow, 4 runs, 0 skips 622 decicycles in pow, 8 runs, 0 skips 477 decicycles in pow, 16 runs, 0 skips 368 decicycles in pow, 32 runs, 0 skips 317 decicycles in pow, 64 runs, 0 skips 291 decicycles in pow, 128 runs, 0 skips 277 decicycles in pow, 256 runs, 0 skips 268 decicycles in pow, 512 runs, 0 skips 265 decicycles in pow, 1024 runs, 0 skips 263 decicycles in pow, 2048 runs, 0 skips 263 decicycles in pow, 4095 runs, 1 skips 260 decicycles in pow, 8191 runs, 1 skips Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Sebastian Dröge	9aebea0a4d	avcodec/h264: Set CORRUPT flag on output frames that are not fully recovered In the merge commit `78265fcfee` this behaviour was broken and the CORRUPT flag would never ever be set on a frame. However the flag on the AVCodecContext was taken into account properly, including AV_CODEC_FLAG2_SHOW_ALL. The reason for this was that the recovered field of the next output picture was always set to TRUE whenever one of the two AVCodecContext flags was set, which made it impossible to detect later, before outputting, if the frame was really recovered or not. Now don't set it to TRUE unless the frame is really recovered and check the AVCodecContext flags right before outputting.
