Viblast Player Release History
xhrBeforeCreatecallback is invoked before each HTTP request is actually created. This allows for changing the URL and method of the request.
- Fix the issue with program date time calculation for DVR streams.
- Add new parameter "dvr-min-duration", which instructs the player to consider the stream as a DVR one if the playlist duration is greater than it. The default value is
- Fix the issue with seek if the HLS segment timestamp is not aligned to the expected playlist timestamp
- Remove wrong log messages for deprecated WebRTC API usage /Firefox only/
