* os_support: Don't try to return the service name as a string in getnameinfoMartin Storsjö2015-10-30
| | | | | | | | | | | | | Some systems may be lacking getservbyport; the previous ifdef wasn't quite enough since it still assumed that struct servent was defined, as pointed out by Clément Gregoire. Simply remove the possibility to return non-numeric services in getnameinfo; no caller of getnameinfo within libavformat currently try to use getnameinfo for retrieving the port number without NI_NUMERICSERV, and falling back on getservbyport may be non-threadsafe.

* 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).

* win32: Make ff_win32_open more robustReimar Döffinger2013-03-27
| | | | | | | | | | | - Make MultiByteToWideChar fail when it encounters invalid encoding. Without this, invalid characters might just be skipped - When MultiByteToWideChar fails, assume the file name is in CP_ACP and open it via normal open function, even when the file will be written - When malloc fails return error instead of crashing Signed-off-by: Martin Storsjö <martin@martin.st>

* network: Always use our version of gai_strerror on windowsMartin Storsjö2012-07-15
| | | | | | | | Even if linking directly to getaddrinfo, use our version of gai_strerror instead of the system's version. Microsoft explicitly documents that their version of gai_strerror is thread-unsafe. Signed-off-by: Martin Storsjö <martin@martin.st>

* os_support: Rename the poll fallback function to ff_pollMartin Storsjö2012-06-30
| | | | | | | | | | | | The fallback function is a non-static function, we shouldn't be defining non-static functions outside of the proper ff/av prefix namespaces. This is especially important for a function like poll, which other parties (other libraries, or executables linking these libraries) also might provide similar but incompatible fallbacks for. Signed-off-by: Martin Storsjö <martin@martin.st>
* os_support: Don't compare a negative number against socket descriptorsMartin Storsjö2012-06-30
| | | | | | | | The fds are unsigned integers in the windows definition of struct sockfds. Due to this, the comparison if (fds[i].fd > n) was always false. Signed-off-by: Martin Storsjö <martin@martin.st>
* os_support: Include all the necessary headers for the win32 open functionRonald S. Bultje2012-06-30
| | | | | | | | | | | | | io.h is required for open and _wopen, and fcntl.h is required for the O_CREAT flag. On mingw, fcntl.h is included by os_support.h (and the mingw fcntl.h includes io.h), but include it explicitly here since this implementation requires it. Also move the #undef open up. open must not be defined to ff_win32_open while including the headers that declare the open function. On mingw, this happened in os_support.h before open was redirected. Signed-off-by: Martin Storsjö <martin@martin.st>
* configure: Check for sys/time.hRonald S. Bultje2012-06-26
| | | | | | | | Apparently this include is needed on some systems for building the poll fallback (for the timeval struct for select?), but it isn't available on all systems. Thus only include it if it exists. Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun2011-05-12
| | | | | | | | | | | | | | | | Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.
* Handle unicode file names on windowsKirill Gavrilov2011-04-24
| | | | | | | | | | | | | All file names should be in UTF-8 within libavformat. This is handled by mapping the open() function to an internal one in os_support.h for windows. fopen() could be overridden in the same way, but if that would be used from ffmpeg.c, it would add a dependency on an ff prefixed internal lavf function.

* os_support: make poll() fallbacks conditional on CONFIG_NETWORKMans Rullgard2011-01-28
| | | | | | | | | | | poll() is only used by networking code, so the fallback should only be built if networking is enabled. Also remove CONFIG_FFSERVER condition from the declarations. This should fix building on systems without poll(), broken by a8475bbdb64e638bd8161df9647876fd23f8a29a. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Move resolve_host() to ffserver.cMåns Rullgård2010-03-08
| | | | | | | | | | This deprecated function is only used by ffserver, yet does not have a prototype visible there. In the long term, ffserver should be made IPv6-aware. In the meantime, this change removes cruft from lavf and fixes some warnings in ffserver. Originally committed as revision 22329 to svn://svn.ffmpeg.org/ffmpeg/trunk
