We have a video streaming server set up by someone who left the organization. Those of us left are in the dark on the intricacies of streaming video. The wowza streaming engine is on site. Firefox, Chrome, IE, and Edge are set to use the DASH.js player. Starting on May 29th, we started to get reports that longer Video On Demand videos would stop playing on Chrome, Firefox, IE, and Edge. There are NO issues with Android, IPhone, or Safari. We updated the Wowza Streaming Engine software to the latest and changed the provisioning to get rid of the one error in the wowza logs (First frame of video has a non-zero CTTS value [66], playback may not work on all browsers, try setting HTTPStreamer/Properties boolean property mpegdashAdjustCTTSForFirstKeyFrameToZero to true). No matter what version of the dash reference player we use ([https://reference.dashif.org/dash.js/](https://reference.dashif.org/dash.js/)), we get the same problem of the audio buffer filling up. This was not a problem with any of our videos before May 29th. It seems that the issue is not with the player, but either with the manifest files or the configuration of the streaming engine. Does anyone have any recommendations? We would use the wowza player, which works for Chrome, Firefox, IE, and Edge, but we must have captioning working.
