* Remove final semicolon from some macrosMans Rullgard2011-02-10
| | | | | | This avoids double semicolons after macro expansion. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dvbsubenc: Fix placement of the object versionRonen Mizrahi2011-02-10

* Do not fail DVB sub decoding because of a few padding bytesReimar Döffinger2011-02-10
| | | | | | | | | Instead of returning an error when bytes are left over, just return the number of actually used bytes as other decoders do. Instead add a special case so an error will be returned when none of the data looks valid to avoid making debugging a pain. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Add x86-optimized versions of exponent_min().Justin Ruggles2011-02-10

* Remove incorrect return statement from avcodec_thread_free()Mans Rullgard2011-02-10
| | | | | | | The function return type is void, so a return statement with an expression is forbidden (and pointless). Signed-off-by: Mans Rullgard <mans@mansr.com>
* ivi_dsp: remove semicolons after function definitionsMans Rullgard2011-02-10

* Fix build with threading disabledMans Rullgard2011-02-09
| | | | | | | | The avcodec_thread_free() compatibility wrapper calls ff_thread_free(), which is not defined when threading is disabled. Make this call conditional. Signed-off-by: Mans Rullgard <mans@mansr.com>
* w32thread: add missing #include thread.hMans Rullgard2011-02-09
| | | | | | This should fix building with win32 threads. Signed-off-by: Mans Rullgard <mans@mansr.com>
* check sample_fmt in avcodec_openReimar Döffinger2011-02-09
| | | | | | check AVCodecContext->sample_fmt against AVCodec->sample_fmts[] to ensure that the encoder supports the specified sample format. Error out if it doesn't. Previously, it would continue and output garbage. Fixes issue 2587.
* vp3: Frame-based multithreading supportAlexander Strange2011-02-09
| | | | | | | | | | | | | | | | | | | Decode times for big_buck_bunny_720p_stereo: 1 thread: real 1m14.227s user 1m13.104s sys 0m1.108s 2 threads: (33% faster) real 0m49.329s user 1m33.735s sys 0m1.834s 3 threads: (44% faster) real 0m41.593s user 1m44.884s sys 0m1.967s
* Deprecate avcodec_thread_init()Alexander Strange2011-02-09
| | | | | | | | | | | | | | As a side effect of the last commit, avcodec_open() now calls it automatically, so there is no longer any need for clients to call it. Instead they should set AVCodecContext.thread_count. avcodec_thread_free() is deprecated, and will be removed from avcodec.h at the next MAJOR libavcodec bump. Rename the functions to ff_thread_init/free, since they are now internal. Wrappers are provided to maintain API compatibility. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Frame-based multithreading framework using pthreadsAlexander Strange2011-02-09
| | | | | | See doc/multithreading.txt for details on use in codecs. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Update qmin/qmax values for libx264 presetsJason Garrett-Glaser2011-02-08
| | | | | Also allow qmin/qmax to go up to 69 (the current max value for libx264). This will have to increase when we add 9/10-bit support.
* Fix broken vbv_buffer_init handling in libx264.cJason Garrett-Glaser2011-02-08
| | | | | | Due to being pants-on-head retarded, libavcodec defaults this to zero, which results in broken output. This didn't affect ffmpeg.c, which sets it itself, but caused problems for other calling apps using VBV.
* VP8: idct_mb optimizationsJason Garrett-Glaser2011-02-08
| | | | Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet.
* Fix ff_emu_edge_core_sse() on Win64.Ronald S. Bultje2011-02-08
| | | | | | | Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict on the size of registers and which registers are being used for operations where multiple are available. This fixes segfaults in emulated_edge() function calls on Win64.
* logging: downgrade recoverable errors to warningsStefan Kost2011-02-08
| | | | | | | | In all 3 cases, the decoding continues and thus a warning would be sufficient. Helps application that catch them with own log handers to handle them accordingly. Signed-off-by: Mans Rullgard <mans@mansr.com>
* h264: define FF_PROFILE_H264_HIGH_444 to the correct valueJanne Grunau2011-02-08
| | | | | It was removed in fe9a3fb since it had the wrong value. Add profile name for it.
* VP8: ARM NEON optimisations for dsp functionsMans Rullgard2011-02-07
| | | | | | | This adds NEON optimised versions of all functions in VP8DSPContext. Based on initial work by Rob Clark. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dvbsubdec: pass correct input buffer sizeJindrich Makovicka2011-02-07
| | | | | | | | | | | In some places, dvbsubdec passes improper input buffer size to bitstream reading functions, not accounting for reading pointer updates. Fixed by using buffer_end - buffer pointer instead of fixed buffer length. Signed-off-by: Jindrich Makovicka <makovick@gmail.com> Signed-off-by: Mans Rullgard <mans@mansr.com>

* pass QDMC extradata to the decoderSascha Sommer2011-02-06
| | | | | | | Makes playing QDMC files in MPlayer work when using the libavformat demuxer. Problem was that the extradata was not passed from demuxer to decoder. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* ac3enc: Change EXP_DIFF_THRESHOLD to 500.Justin Ruggles2011-02-02
| | | | | | | | | This patch changes the exponent difference threshold in the exponent strategy decision function of the AC-3 encoder. I tested lowering in increments of 100. From 1000 down to 500 generally increased in quality with each step, but 400 was generally much worse. Signed-off-by: Mans Rullgard <mans@mansr.com>
