From 7f7ee86d5a494ddbcb22c83dec970f38a8ccd7b4 Mon Sep 17 00:00:00 2001 From: Aaron Levinson Date: Fri, 5 May 2017 17:59:21 -0700 Subject: avdevice/decklink: fix MSVC build issues Purpose: Made minor changes to get the decklink avdevice code to build using Visual C++. Notes: Made changes to configure per Hendrik Leppkes's review of first and second versions of patch. Also made slight alterations per Marton Balint's reviews. Comments: -- configure: Added if enabled decklink section and setting decklink_indev_extralibs and decklink_outdev_extralibs here for both mingw and Windows. Also eliminated the setting of these variables in the mingw section earlier in the file. -- libavdevice/decklink_common.cpp: Switched the order of the include of libavformat/internal.h to workaround build issues with Visual C++. See comment in file for more details. -- libavdevice/decklink_dec.cpp: a) Rearranged the include of libavformat/internal.h (for reasons as described above). b) Made slight alteration to an argument for call to av_rescale_q() to workaround a compiler error with Visual C++. This appears to only be an issue when building C++ files with Visual C++. See comment in code for more details. -- libavdevice/decklink_enc.cpp: Rearranged the include of libavformat/internal.h (for reasons as described above).
