* dca: use EXT_AUDIO_ID field to determine core extensionsAnssi Hannula2011-02-24
| | | | | | | | | This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode. Signed-off-by: Mans Rullgard <mans@mansr.com>
* vmdaudio: output 8-bit audio as AV_SAMPLE_FMT_U8.Justin Ruggles2011-02-23
| | | | | | There is no need to expand to 16-bits. Just use memcpy() to copy the raw data. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* libavformat: Remove FF_NETERRNO()Martin Storsjö2011-02-23
| | | | | | | | | | | | | | Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR() error codes. Provide fallback definitions of other errno.h network errors, mapping them to the corresponding winsock errors. This eases catching these error codes in common code, without having to distinguish between FF_NETERRNO(EAGAIN) and AVERROR(EAGAIN). This fixes roundup issue 2614, unbreaking blocking network IO on windows. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Add more AVC Intra FOURCCsBenjamin Larsson2011-02-22

* mpegtsenc: use correct PES stream_id for AACTony Strauss2011-02-21
| | | | | | | This adds the AAC codec to the list of audio codecs that results in a PES stream_id of 0xc0 (audio stream). Signed-off-by: Mans Rullgard <mans@mansr.com>

* ppc: fix vc1 inverse transform, unbreak buildMans Rullgard2011-02-21
| | | | | | | | GCC 4.3 and later are more particular about signedness matching in vector operations. The operations under if(rangered) were missing assignments and thus had no effect. Signed-off-by: Mans Rullgard <mans@mansr.com>

* VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje2011-02-21
| | | | | Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.

* VC1: inline vc1_put_block() in vc1_decode_i_blocks().Ronald S. Bultje2011-02-21
| | | | | | Advantage is that it allows us to combine several loops into a single one, and these can eventually be merged into the IDCT itself. Also, it allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
* lavfi: put color source in a dedicated fileStefano Sabatini2011-02-21

* lavfi: add drawutilsStefano Sabatini2011-02-21
| | | | | | | Add drawutils.h and drawutils.c, and use them in the pad filter. The new functions are going to be shared by other filters. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Makefile: include deps from tools directoryMans Rullgard2011-02-20
| | | | | | | | This ensures the tools are rebuilt when necessary. Specifically, lavfi-showfiltfmts was sometimes not rebuilt causing spurious test failures. Signed-off-by: Mans Rullgard <mans@mansr.com>
* amrnb: use correct size when copying lsf_r arrayMans Rullgard2011-02-20
| | | | | | lsf_r is an array of int16_t, not float. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: use raw opcode for xgetbv instructionMans Rullgard2011-02-20
| | | | | | | | | | This allows the CPU detection to work with assemblers not supporting the xgetbv mnemonic. These include clang and some BSD versions. All AVX code will be written for yasm, where the main assembler is not involved. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Update version and APIchanges.Ronald S. Bultje2011-02-20
| | | | | | Update libavformat/version.h and doc/APIChanges after renaming init_put_byte() and ByteIOContext to ffio_init_context() (private) and AVIOContext, (public), and deprecating the originals.
* avio: move init_put_byte() to a new private header and rename itAnton Khirnov2011-02-20
| | | | | | | init_put_byte should never be used outside of lavf, since sizeof(AVIOContext) isn't part of public ABI. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* avio: rename ByteIOContext to AVIOContext.Anton Khirnov2011-02-20

* VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv().Ronald S. Bultje2011-02-20
| | | | | | | | Advanced profile never uses "range reduction", so vc1_put_block() quite literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv(). By inlining the function, we can prevent calling IDCT8x8 if CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the [0,256] range, but can instead use put_signed_pixels_clamped().
* x86: check for AVX supportMans Rullgard2011-02-20
| | | | | | This adds configure and runtime checks for AVX support on x86 CPUs. Signed-off-by: Mans Rullgard <mans@mansr.com>
* MMS: also discover streams in extended stream properties objectMarton Balint2011-02-19

* dsputil_mmx.c: remove ff_vector128.Ronald S. Bultje2011-02-19
| | | | Remove ff_vector128, it is identical to ff_pb_80.
* Fix invalid reads in VC1 decoderReimar Döffinger2011-02-19
| | | | Patch discussed and taken from https://roundup.ffmpeg.org/issue2584
* Fix VP3 edge emulationDavid Conrad2011-02-19
| | | | | | With negative stride, the start of the edge_emu buffer should be pointing to the last line, not the end of the buffer. With positive stride, pointing to the end of the buffer was completely wrong.
