* x86: bswap: remove test for bswap instructionMans Rullgard2011-12-12
| | | | | | | | Firstly, this test never worked as intended, always reporting success. Secondly, bswap is available from 486 onward and can thus be assumed present. Signed-off-by: Mans Rullgard <mans@mansr.com>
* bswap: make generic implementation more compiler-friendlyMans Rullgard2011-12-12
| | | | | | | | With these changes, gcc 4.5 and later recognise it as a bswap and use the proper instructions on ARM and x86. On x86, the 16-bit bswap is recognised from gcc 4.1. Signed-off-by: Mans Rullgard <mans@mansr.com>
* h264: remove useless castMans Rullgard2011-12-12

* proresdec: fix decode_slice() prototypeMans Rullgard2011-12-12
| | | | | | | | Make the function prototype match the argument of AVCodecCntext.execute() and remove the cast hiding this mismatch. Signed-off-by: Mans Rullgard <mans@mansr.com>
* x86: cabac: replace explicit memory references with "m" operandsMans Rullgard2011-12-11
| | | | | | | | This replaces the explicit offset(reg) memory references with "m" operands for the same locations. As a result, one fewer register operand is needed for these inline asm statements. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avplay: don't request a stereo downmixJustin Ruggles2011-12-11
| | | | Multi-channel output works just fine for me with SDL 1.2.14.

* lavc: avoid invalid memcpy() in avcodec_default_release_buffer()Mans Rullgard2011-12-11
| | | | | | | | | | When the buf and last pointers are equal, the FFSWAP() results in an invalid call to memcpy() with same source and destination on some targets. Although assigning a struct to itself is valid C99, gcc does not check for this before calling memcpy(). See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667 Signed-off-by: Mans Rullgard <mans@mansr.com>
* lavu: replace int/float punning functionsMans Rullgard2011-12-11
| | | | | | | | | | | | | | | | | | The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>
* lavfi: install libavfilter/vsrc_buffer.hAndrey Utkin2011-12-11
| | | | | | It declares API necessary for filtering apps. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* Remove extraneous semicolonsMans Rullgard2011-12-11
| | | | | | These semicolons cause invalid empty top-level declarations. Signed-off-by: Mans Rullgard <mans@mansr.com>
* sdp: Restore the original mp4 format h264 extradata if convertedMartin Storsjö2011-12-11
| | | | | | | | | If the sdp is generated before the rtp muxer is initialized (e.g. as when called from the rtsp muxer), this has to be done, otherwise the rtp muxer doesn't know that the input really is in mp4 format. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Add support for mp4 format h264Luca Abeni2011-12-11
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Simplify code by introducing a separate end pointerMartin Storsjö2011-12-11
| | | | | | Also remove redundant parentheses. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Use the actual converted sample for RTP hintingMartin Storsjö2011-12-11
| | | | | | | | | | | | | If an annex b bitstream is muxed into mov, the actual written sample is reformatted to mp4 syntax before writing. Currently, the RTP hints that copy data from the normal video track, where the payload data might be offset compared to the original sample that the RTP hinting used (when 3 byte annex b startcodes have been converted into 4 byte mp4 format startcodes).

* Warn about avserver being broken.Anton Khirnov2011-12-10
| | | | Also remove mentions of it from other avtools' manuals.
* avconv: drop code for special handling of avserver streams.Anton Khirnov2011-12-10
| | | | | | | | It's broken and doesn't work anyway. This patch means that avconv will ignore encoding options from the ffm file and will instead use whatever is provided on the commandline as for normal output.
* rawdec: don't set codec timebase.Anton Khirnov2011-12-10
| | | | | It's not supposed to be set outside of lavc. Set r_frame_rate and avg_frame_rate instead.
