Freenet M3U8 video stream generator
#!/bin/bash
# This script uses x264 and ffmpeg to recode an input video to low-bitrate MPEG-TS segmented h264
# stream that is suitable for streaming over the web and can be inserted into Freenet.
# Settings have been chosen to strongly prefer quality over encoding speed under conditions of an
# extremely low bitrate, to make the result suitable for direct streaming over Freenet.
