* WIP with new transcoder progress monitor * A whole different WIP in progress monitoring via local PUTs * Use an actual hls playlist parser to rewrite master playlist * Cleanup * Private vs public path for thumbnail generation * Allow each storage provider to make decisions of how to store different types of files * Simplify inbound file writes * Revert * Split out set stream as connected/disconnected state methods * Update videojs * Add comment about the hls handler * Rework of the offline stream state. For #85 * Delete old unreferenced video segment files from disk * Cleanup all segments and revert to a completely offline state after 5min * Stop thumbnail generation on stream stop. Copy logo to thumbnail on cleanup. * Update transcoder test * Add comment * Return http 200 on success to transcoder. Tweak how files are written to disk * Force pixel color format in transcoder * Add debugging info for S3 transfers. Add default ACL. * Fix cleanup timer * Reset session stats when we cleanup the session. * Put log file back * Update test * File should not be a part of this commit * Add centralized shared performance timer for use anywhere * Post-rebase cleanup * Support returning nil from storage provider save * Updates to reflect package changes + other updates in master * Fix storage providers being overwritten * Do not return pointer in save. Support cache headers with S3 providers * Split out videojs + vhs and point to specific working versions of them * Bump vjs and vhs versions * Fix test * Remove unused * Update upload warning message * No longer valid comment * Pin videojs and vhs versions
