* w32threads: Use newer thread synchronization functions when targeting VistaMartin Storsjö2014-08-13
| | | | | | | | | | | | | | | | | When explicitly targeting Vista or newer (which only happens if the caller explicitly sets _WIN32_WINNT to a high enough value via the extra cflags option - otherwise configure script sets -D_WIN32_WINNT=0x0502), we already unconditionally link to the ConditionVariable functions, since 4622f11f9. Similarly use the newer -Ex versions of CreateEvent, CreateSemaphore, InitializeCriticalSection and WaitForSingleObject, that all appeared in Vista. When building Windows Store applications, the older versions of these functions aren't available, only the -Ex functions. When doing such a build, the user can set -D_WIN32_WINNT=0x0600 to forcibly use the newer functions instead. Signed-off-by: Martin Storsjö <martin@martin.st>
* http: Stop reading after receiving the whole file for non-chunked transfersMartin Storsjö2014-08-13
| | | | | | | | | | | | | | | | | | | | | | | | Previously this logic was only used if the server didn't respond with Connection: close, but use it even for that case, if the server response is non-chunked. Originally the http code has relied on Connection: close to close the socket when the file/stream is received - the http protocol code just kept reading from the socket until the socket was closed. In f240ed18 we added a check for the file size, because some http servers didn't respond with Connection: close (and wouldn't close the socket) even though we requested it, which meant that the http protocol blocked for a long time at the end of files, waiting for a socket level timeout. When reading over tls, trying to read at the end of the connection, when the peer has closed the connection, can produce spurious (but harmless) warnings. Therefore always voluntarily stop reading when the specified file size has been received, if not using a chunked transfer encoding. (For chunked transfers, we already return 0 as soon as we get the chunk header indicating end of stream.) Signed-off-by: Martin Storsjö <martin@martin.st>

* configure: Don't pass MSVC compiler options -M[TD] to armasmMartin Storsjö2014-08-10
| | | | | | | | | | | The -MD option (for enabling a dynamically linked crt) gets interpreted as a cpp option for generating dependency information (into a file named '-.d', when preprocessing to a pipe). We shouldn't be passing any and all C compiler flags to armasm (which is a plain assembler, only with cpp bolted on via gas-preprocessor), but these are the main conflicting ones.

* hevc_filter: avoid excessive calls to ff_hevc_get_ref_list()Anton Khirnov2014-08-09
| | | | | | | | 1) each of the loops run within a single CTB, so the relevant reference list is constant 2) when that CTB is, or lies on the same slice as, the current one, we can use a simple access instead of a relatively expensive call to ff_hevc_get_ref_list()
