Use getpid instead of GetCurrentProcessId as the latter calls into io-layer which is not initialzed at this point.
Take shared file lock before collecting file share_info.
Support for video/mp4, video/ogg, video/webm

Added support for the three leading HTML5 Video mime types
.mp4 video/mp4
.ogv video/ogg
.webm video/webm

When Internet Explorer 10 or 11 receives application/octet-stream as the mime type for HTML5 video, it will not play the video. This resolves the issue in an Apache/mod_mono environment.
Support for audio/ogg and audio/mp4

.ogg, .oga audio/ogg
.mp4a, .aac audio/mp4
http://tools.ietf.org/html/rfc4337
