Hi,
1. The latency for HDS and HLS playback may be reduced by reducing the chunkLength parameter. For VOD streams, you may adjust the clientSideBuffer parameter in the mediaStorage section of the primary configuration file, config.lua. Please refer to the VOD section of the EMS User Guide for details.
2. At the moment, once the input stream stops, the output stream also stops. We currently do not replace the lost input stream with a demo video or picture. If the keepAlive parameter in the pullstream command is missing or is set to 1, the output stream will be restored once the input stream is restored.
Cheers,
Don
