* libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as ↵Martin Storsjö2013-08-10
| | | | | | | | | | | | | | | well This used to only be necessary in static builds (when using the dynamically linked C runtime), since the _imp prefixed symbols do exist when linking to the actual DLL. When building testprogs, however, the current library (e.g. libavutil for some of the testprogs) is linked statically. This fixes make fate on DLL builds when using the dynamically linked C runtime.

* ff_socket: put out-of-line and fallback to fcntl() for close-on-execRémi Denis-Courmont2013-08-09
| | | | | | | This supports non-Linux systems (SOCK_CLOEXEC is non-standard) and older Linux kernels to the extent possible. Signed-off-by: Martin Storsjö <martin@martin.st>

* file: Move win32 utf8->wchar open wrapper to libavutilMartin Storsjö2013-08-08
| | | | | | | | | | | | | When libavformat was changed to use the new avpriv_open function in 51eb213d001, this silently bypassed the existing wrapper for win32. Move the win32 wrapper into libavutil/file.c to make sure it gets called everywhere (not just in the libavformat case). This makes sure that non-ascii file names gets opened properly (where file names internally are stored as utf8, but they get converted to wchar_t and opened with _wsopen).

* h264dsp: Factorize code into a new function, h264_find_start_code_candidateBen Avison2013-08-08
| | | | | | | | | | | | | | | This performs the start code search which was previously part of h264_find_frame_end() - the most CPU intensive part of the function. By itself, this results in a performance regression: Before After Mean StdDev Mean StdDev Change Overall time 2925.6 26.2 3068.5 31.7 -4.7% but this can more than be made up for by platform-optimised implementations of the function.

* h264_parser: Initialize the h264dsp context in the parser as wellBen Avison2013-08-08
| | | | | | | | | | | | | | | Each AVStream struct for an H.264 elementary stream actually has two copies of the H264DSPContext struct (and in fact all the other members of H264Context as well): ((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp ((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp but only the first of these was actually being initialised. This prevented the addition of platform-specific implementations of parser-related functions. Signed-off-by: Martin Storsjö <martin@martin.st>

* avio: Add const qualifiers to ffio_read_indirectBen Avison2013-08-08
| | | | | | | This provides at least some protection against potential accidental corruption of AVIO buffer workspace. Signed-off-by: Martin Storsjö <martin@martin.st>

* cmdutils: Only do the windows-specific commandline parsing on _WIN32Diogo Franco2013-08-08
| | | | | | | | | | | | | Fixes commandline parsing on Cygwin (on 64 bit, and on very recent 32 bit), where the configure check does find the CommandLineToArgvW function (since it exists in the link libraries and in the headers), but whose GetCommandLineW() only returns the application's path. (This is due to a cygwin internal optimization, see http://cygwin.com/ml/cygwin/2013-07/msg00538.html for details.) Arguments are only given through main's argc/argv, and they're already UTF-8.

| | | | | | | It's only relevant for the RTSP demuxer. Similarly, the custom_io flag is only present in the SDP demuxer options list. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | This lowers the level of warnings printed if trying to connect to a host name that provides both v6 and v4 addresses but the service only is available on the v4 address (often occurring for 'localhost', with servers that aren't v6-aware).

| | | | | | | | | | | | | The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

* mpegts: Make discard_pid() faster for single-program streamsBen Avison2013-08-05
| | | | | | | | | | | | | When a stream contains a single program, there's no point in doing a PID -> program lookup. Normally the one and only program isn't disabled, so no packets should be discarded.

* mpegts: Remove one memcpy per packetBen Avison2013-08-05
| | | | | | | | | | | | | | This was being performed to ensure that a complete packet was held in contiguous memory, prior to parsing the packet. However, the source buffer is typically large enough that the packet was already contiguous, so it is beneficial to return the packet by reference in most cases.

| | | | | | | | The bitstream buffers are now private and freed by libavcodec. For backward compatibility, the hold bitstream buffer pointer is left NULL (applications were supposed to av_freep() it). Signed-off-by: Anton Khirnov <anton@khirnov.net>
