* Discard partial packet of last frame for fate-wmv8-drm to avoid test failsReimar Döffinger2010-12-18
| | | | | | due to VC-1 decoder overreads resulting in different output. Originally committed as revision 26055 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add test for ASF -cryptokey that tests only demuxing, but both audio and videoReimar Döffinger2010-12-18
| | | | | | to complement the existing video-only decode test. Originally committed as revision 26054 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change ASF demuxer to return incomplete last packets.Reimar Döffinger2010-12-18
| | | | | | | Whether the behaviour for streams using scrambling makes sense is unclear. Originally committed as revision 26053 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Add some simple fallbacks for normal bit allocation failure.Justin Ruggles2010-12-17
| | | | | | | | This allows encoding with lower bitrates by decreasing exponent bits first, then decreasing bandwidth if the user did not specify a specific cutoff frequency. Originally committed as revision 26050 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Check user-specified cutoff frequency in validate_options().Justin Ruggles2010-12-17

* Do not calculate psd and masking curve if exponents are being reused.Justin Ruggles2010-12-17
| | | | | | Approx. 20% faster in function bit_alloc_masking(). Originally committed as revision 26042 to svn://svn.ffmpeg.org/ffmpeg/trunk
* cosmetics: reindent after last commitJustin Ruggles2010-12-16
| | | | Originally committed as revision 26041 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Copy bap from previous block when exponent strategy is EXP_REUSE.Justin Ruggles2010-12-16
| | | | | | | | | We can do this because exponents are the only bit allocation parameters which change from block-to-block currently. Approx. 57% faster in function bit_alloc(). Approx. 25% faster overall encoding. Originally committed as revision 26040 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Count grouped mantissas for each block all at once at the end of bitJustin Ruggles2010-12-16
| | | | | | | allocation for each block. 24% faster in function bit_alloc(). Approx. 10% faster overall encoding. Originally committed as revision 26039 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Count bits for fixed parameters at start of encoding rather than in everyJustin Ruggles2010-12-16
| | | | | | frame. Originally committed as revision 26038 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use a LUT for number of exponent groups. This avoids recalculating it forJustin Ruggles2010-12-16
| | | | | | every block and channel for every frame. Originally committed as revision 26037 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Speed up group minimum and group output calculations for EXP_D25 and EXP_D45Justin Ruggles2010-12-16
| | | | | | | in encode_exponents_blk_ch() by removing the inner loops. This is about 30-40% faster for the modified sections. Originally committed as revision 26036 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Convert a for() loop into a while() loop for the downward part of the exponentJustin Ruggles2010-12-16
| | | | | | delta limiting. Originally committed as revision 26035 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Redesign encode_exponents_blk_ch() so that duplicate exponent sets are noJustin Ruggles2010-12-16
| | | | | | | | longer required. This gets rid of the temp buffer as well as encoded_exp in AC3EncodeContext. It also allows for skipping the exponent grouping for EXP_D15. 56% faster in encode_exponents_blk_ch(). Originally committed as revision 26034 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use optimized function DSPContext.sad[0]() instead of calc_exp_diff().Justin Ruggles2010-12-16
| | | | | | 90% faster compute_exp_strategy(). Originally committed as revision 26033 to svn://svn.ffmpeg.org/ffmpeg/trunk
* configure: Avoid warnings if av_always_inline is disabledMartin Storsjö2010-12-16
| | | | | | | | | | | | | | | This macro is disabled if --enable-small or --disable-optimizations are set. Currently, this leads to warnings about functions being defined but not used, for functions in header files. By defining av_always_inline as inline or as av_unused, we avoid these warnings. This doesn't make a normal build with --enable-small any larger, since the compiler probably chooses not to inline these functions even if they're marked as inline. Originally committed as revision 26032 to svn://svn.ffmpeg.org/ffmpeg/trunk
* cosmetics: pretty-printing after last commitJustin Ruggles2010-12-16
| | | | Originally committed as revision 26031 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add a goto for init failure instead of duplicate calls to ac3_encode_close().Justin Ruggles2010-12-16
| | | | Originally committed as revision 26030 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use pre-allocated temp buffers in mdct512().Justin Ruggles2010-12-16
| | | | | | 5% faster in function. Originally committed as revision 26029 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Write results of post-rotation complex multiply directly to output.Justin Ruggles2010-12-16
| | | | | | 2% faster in function mdct512(). Originally committed as revision 26028 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use memcpy() instead of a for loop in mdct512().Justin Ruggles2010-12-16
| | | | | | 8% faster in function. Originally committed as revision 26027 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Allocate all large per-channel arrays using av_malloc().Justin Ruggles2010-12-16
| | | | | | Decreases memory usage for less than 6 channels. Originally committed as revision 26026 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make windowed_samples 16-byte aligned.Justin Ruggles2010-12-16
| | | | | | This will allow future SIMD optimization of the window function. Originally committed as revision 26025 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Allocate planar_samples using av_mallocz().Justin Ruggles2010-12-16
| | | | | | Lowers memory usage when encoding less than 6 channels. Originally committed as revision 26024 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Allocate bap and bap1 buffers using av_malloc().Justin Ruggles2010-12-15
| | | | | | | | | This reduces the memory footprint when using less than 6 channels. Modify bit allocation to swap the 2 buffers instead of using memcpy() and use per-block pointers for bap. This is slightly faster (0.3%) in function cbr_bit_allocation(). Originally committed as revision 26023 to svn://svn.ffmpeg.org/ffmpeg/trunk
* rtsp: Don't set the RTP time base from the sample rate if no sample rate is setMartin Storsjö2010-12-15
| | | | | | | | | This also reverts SVN rev 26016, which incorrectly overwrote the time base with 90 kHz for all streams, regardless of what was set by the SDP parsing. The stream that triggered the fix in 26016 still works after this commit. Originally committed as revision 26022 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove last_samples[] and copy directly from planar_samples[].Justin Ruggles2010-12-15
| | | | | | | | Avoids memcpy that was used to store last samples for next frame. Approx. 3% faster in function deinterleave_input_samples() and reduces memory usage by 3kB. Originally committed as revision 26021 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove unneeded line. key_frame is already set to 1 in avcodec_alloc_frame().Justin Ruggles2010-12-15
| | | | Originally committed as revision 26020 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 26019 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Separate most of the per-block arrays into a separate per-block struct.Justin Ruggles2010-12-15
| | | | Originally committed as revision 26018 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split bit allocation search into a separate function.Justin Ruggles2010-12-15
| | | | Originally committed as revision 26017 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reinstate default time_base for rtp streamsLuca Barbato2010-12-15
| | | | | | The generic default is 0/0 and that obviously triggers once the value is used. Originally committed as revision 26016 to svn://svn.ffmpeg.org/ffmpeg/trunk
* SVQ3: Allow decoding if thread_count is > 1Alexander Strange2010-12-15
| | | | | | | svq3 still doesn't support multithreading, but it's simpler for clients if they can enable threading for all codecs by default. Originally committed as revision 26015 to svn://svn.ffmpeg.org/ffmpeg/trunk
* tcp: Check url_interrupt_cb if connect was interrupted by a signalThomas Guillem2010-12-14
| | | | | | | | This makes it possible to abort a blocking connect call. Patch by Thomas Guillem, thomas dot guillem at gmail Originally committed as revision 26014 to svn://svn.ffmpeg.org/ffmpeg/trunk
