* lavu: Add av_strnstr()Vladimir Pantelic2013-01-25
| | | | | | | This is a length limited version of strstr() Signed-off-by: Vladimir Pantelic <vladoman@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* h264: Allow discarding the cropping information from SPSVittorio Giovara2013-01-25
| | | | | | Some 3D systems overload the meaning of the field for other purposes. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* arm: Add mathops.h to ARCH_HEADERS listDiego Biurrun2013-01-24
| | | | It is an arch-specific header not suitable for standalone compilation.
* avstring: K&R formatting cosmeticsLuca Barbato2013-01-24

* build: Make the H.264 parser select h264qpelDiego Biurrun2013-01-24
| | | | It is required for building the shared H.264 code.
* x86: h264qpel: add cpu flag checks for init functionJanne Grunau2013-01-24
| | | | | The code was copied from per cpu extension init function so the checks for supported extensions was overlooked.
* h264: copy h264qpel dsp context to slice thread copiesJanne Grunau2013-01-24
|
* arm: h264qpel: use neon h264 qpel functions only if supportedJanne Grunau2013-01-24
|
* dsputil: Separate h264 qpelMans Rullgard2013-01-24
| | | | | | | | | | The sh4 optimizations are removed, because the code is 100% identical to the C code, so it is unlikely to provide any real practical benefit.

* doc: fix dependencies in pod generationLuca Barbato2013-01-24
| | | | The script can and will change.
* openbsd: configure: Stop enabling PIC by defaultDiego Biurrun2013-01-24
| | | | | | Previously PIC was enabled as a magic workaround for binaries that built fine, but failed to function at all. This problem no longer exists, possibly since the introduction of symbol versioning.
* rtpenc_chain: Use the original AVFormatContext for getting payload typeMartin Storsjö2013-01-24
| | | | | | | | | | | | | | | | | In ff_rtp_get_payload_type, the AVFormatContext is used for checking whether the payload_type or rtpflags options are set. In rtpenc_chain, the rtpctx struct is a newly initialized struct where no options have been set yet, so no options can be fetched from there. All muxers that internally chain rtp muxers have the "rtpflags" field that allows passing such options on (which is how this worked before 8034130e06), so this works just as intended. This makes it possible to produce H263 in RFC2190 format with chained RTP muxers. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Make sure the output format pointer is setMartin Storsjö2013-01-24
| | | | | | | | Not sure if this actually happens, but we do the same check when checking payload_type further above in the function, so it might be needed. Signed-off-by: Martin Storsjö <martin@martin.st>
* wmv2: Propagate the wmv2 idct permutation type to the dsputils contextMartin Storsjö2013-01-24
| | | | | | | | | | This fixes encoding where the idct setting originally was set to FF_IDCT_AUTO and dsputil chose a default idct with a non-null permutation - even if the permutation tables were updated, dct_quantize in x86/mpegvideoenc_template.c also checked the value of this type variable. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Make sure priv_data is set before reading itMartin Storsjö2013-01-23
| | | | | | | This fixes crashes with muxing H263 into RTSP. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: fix overflow checking in avc_mp4_find_startcode()Xi Wang2013-01-23
| | | | | | | | | | | | The check `start + res < start' is broken since pointer overflow is undefined behavior in C. Many compilers such as gcc/clang optimize away this check. Use `res > end - start' instead. Also change `res' to unsigned int to avoid signed left-shift overflow. Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Martin Storsjö <martin@martin.st>
* rtmp: fix buffer overflows in ff_amf_tag_contents()Xi Wang2013-01-23
| | | | | | | | | | | | | | A negative `size' will bypass FFMIN(). In the subsequent memcpy() call, `size' will be considered as a large positive value, leading to a buffer overflow. Change the type of `size' to unsigned int to avoid buffer overflow, and simplify overflow checks accordingly. Also change a literal buffer size to use sizeof, and limit the amount of data copied in another memcpy call as well.

* rtmp: fix multiple broken overflow checksXi Wang2013-01-23
| | | | | | | | | | | | Sanity checks like `data + size >= data_end || data + size < data' are broken, because `data + size < data' assumes pointer overflow, which is undefined behavior in C. Many compilers such as gcc/clang optimize such checks away. Use `size < 0 || size >= data_end - data' instead.

* float_dsp: Include config.h for redefining restrictMartin Storsjö2013-01-23
| | | | | | | | This makes sure that the restrict keyword is mapped to whatever keyword the compiler prefers/supports. This fixes building on MSVC (and possibly on GCC 2.x as well). Signed-off-by: Martin Storsjö <martin@martin.st>

* floatdsp: move scalarproduct_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | This makes the aac decoder and all voice codecs independent of dsputil.
* floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.
* floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp.Ronald S. Bultje2013-01-22
| | | | | | Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.

* vorbisdsp: change block_size type from int to intptr_t.Ronald S. Bultje2013-01-20
| | | | This saves one instruction in the x86-64 assembly.
* lavc: put FF_IDCT_{VP3,H264,CAVS,BINK,EA,WMV2} under FF_API_IDCT.Ronald S. Bultje2013-01-20
| | | | | | This allows us to get rid of them on the next major bump. All of the above are functionally irrelevant, and most of them are unused, except the vp3 one, which is used wrongly in the bfin arch optimizations.
* wmv2: move IDCT to its own DSP context.Ronald S. Bultje2013-01-20
| | | | | | | | | | | This allows us to remove FF_IDCT_WMV2, which serves no practical purpose other than to be able to select the WMV2 IDCT for MPEG (or vice versa) and get corrupt output. Fate tests for all wmv2-related tests change, because (for some obscure reason) they forced use of the MPEG IDCT. You would get the same changes previously by not using -idct simple in the fate test (or replacing it with -idct auto).
