2011-02-18ac3enc: fix bug in stereo rematrixing decision.Justin Ruggles
The rematrixing strategy reuse flags are not reset between frames, so they need to be initialized for all blocks, not just block 0. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 5b54d4b376fbd2c291b8a6dba7d425e28f654bcf)

2011-02-17ac3enc: change default floor code to 7.Justin Ruggles
This is to match the value in every (E-)AC-3 file from commercial sources. It has a negligible effect on audio quality. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 50d7140441b61809ad4ba4ea7b4ad8fe77bc6888)

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2011-02-16Pass VBV delay to the calling application via ctxChristophe Massiot
VBV delay is useful for T-STD compliance in some TS muxers. It is certainly possible to retrieve it by parsing the output of FFmpeg, but getting it from the context makes it simpler and less error-prone.

2011-02-12Set maximum lowres value for the MJPEG decoder to 3.Carl Eugen Hoyos
While 4 works for some samples, 3 is the correct value since 8x8 DCT is used by (m)jpeg.
2011-02-11VP8: optimized mv prediction and decodingJason Garrett-Glaser
Merge find_near_mvs and mv bitstream decoding: don't do prediction steps until absolutely necessary. (cherry picked from commit f3d09d44b70492022964e2ead5f439bb7c96eaa2)
2011-02-11ac3enc: Remove unneeded clipping of shift amount.Justin Ruggles
s->windowed_samples will always have a range of [-32767,32767] due to the window function, so the return value from log2_tab() will always be in the range [0,14]. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 626264b11b5406c0c78c4056cabb63cb650e9bf2)

2011-02-11Do not fail DVB sub decoding because of a few padding bytesReimar Döffinger
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> (cherry picked from commit 4a72765a1c94b05bd3053b1f34f8457a3b71d714)

2011-02-11Remove incorrect return statement from avcodec_thread_free()Mans Rullgard
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> (cherry picked from commit b4668274b944abae61759e796c5cc36ade510f24)

2011-02-11Fix build with threading disabledMans Rullgard
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> (cherry picked from commit 9a77a92c2b6855781d2a4cfab14c67ae4025760c)

2011-02-11check sample_fmt in avcodec_openReimar Döffinger
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. (cherry picked from commit 2cfa2d925808e6cc6fb7a7c133b7cb7622afd37e)

2011-02-11Deprecate avcodec_thread_init()Alexander Strange
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> (cherry picked from commit c0b102ca03fe92250f1ce620aec3836f529fc1d6)

2011-02-09Update qmin/qmax values for libx264 presetsJason Garrett-Glaser
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. (cherry picked from commit c7ac200d15e3240972d269df768068f0e3bb9c2f)
2011-02-09Fix broken vbv_buffer_init handling in libx264.cJason Garrett-Glaser
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. (cherry picked from commit f7f8120fb9a06b5d7fbf5add48a0d8464319a332)
2011-02-09VP8: idct_mb optimizationsJason Garrett-Glaser
Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet. (cherry picked from commit 62457f9052ea15123688455aad866cb070634f13)
2011-02-09Fix ff_emu_edge_core_sse() on Win64.Ronald S. Bultje
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. (cherry picked from commit 17cf7c68ed26a4cb3c7adf7488a38c2e19118918)
2011-02-09logging: downgrade recoverable errors to warningsStefan Kost
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> (cherry picked from commit ae2104791ffa8466d3f6972ed0793b2a165daabe)
2011-02-09h264: define FF_PROFILE_H264_HIGH_444 to the correct valueJanne Grunau
