* avformat/hlsenc: add hls_flag option to write segments to temporary file ↵Aman Gupta2017-02-07
| | | | | | | | | | | | | | | | until complete Adds a `-hls_flags +temp_file` which will write segment data to filename.tmp, and then rename to filename when the segment is complete. This patch is similar in spirit to one used in Plex's ffmpeg fork, and allows a transcoding webserver to ensure incomplete segment files are never served up accidentally.

* lavf/matroskadec: fix is_keyframe for early BlocksChris Cunningham2017-02-06
| | | | | | | | | | | | | | | Blocks are marked as key frames whenever the "reference" field is zero. This breaks for non-keyframe Blocks with a reference timestamp of zero. The likelihood of reference timestamp being zero is increased by a longstanding bug in muxing that encodes reference timestamp as the absolute time of the referenced frame (rather than relative to the current Block timestamp, as described in MKV spec). Now using INT64_MIN to denote "no reference". Reported to chromium at http://crbug.com/497889 (contains sample)

* Revert "avutil/hwcontext_vaapi: fix SEGV in vaTerminate when vaInitialize fails"Mark Thompson2017-02-05
| | | | | | | | | | | The original code is correctly following the API - vaTerminate() must be called to free the resources of a VADisplay after it is created by any of the vaGetDisplay*() calls; it is not necessary to have successfully called vaInitialize() on it. The segfaults which prompted this change must therefore be bugs in libva or the driver it loads. This reverts commit 3606602f1137552ea54f2c259eb140c1e3c026d4.

* configure: instruct MSVC 2015 to properly process UTF-8 string literalsHendrik Leppkes2017-02-04
| | | | | | | | | | | Without the /UTF-8 switch, the MSVC compiler treats all files as in the system codepage, instead of in UTF-8, which causes UTF-8 string literals to be interpreted wrong. This switch was only introduced in VS2015 Update 2, and any earlier versions do not have an equivalent solution. Fixes fate-sub-scc on MSVC 2015+

* avcodec/flacdsp: Avoid undefined operations in non debug buildsMichael Niedermayer2017-02-04
| | | | | | | | | | | | | | | | | | | | | This fixes ubsan warnings in non debug builds by using unsigned operations in debug builds the correct signed operations are retained so that overflows (which should not occur in valid files and may indicate problems in the DSP code or decoder) can be detected. Alternatively they can be changed to unsigned unconditionally, then its not possible though to detect overflows easily if someone wants to test the DSP code for overflows. The 2nd alternative would be to leave the code as it is and accept that there are undefined operations in the DSP code and that ubsan output is full of them in some cases. Similar changes would be needed in some other DSP routines Suggested-by: Matt Wolenetz <wolenetz@google.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
