# Re-Encode Mp4 Video Files using H.264 and AAC audio, optimized for streaming
# Credits: https://superuser.com/a/1551095
#    -c:v libx264 selects the video encoder libx264, which is a H.264 encoder.
#    -preset slow selects the slow x264 encoding preset. Default preset is medium. Use the slowest preset that you have patience for.
#    -crf 20 selects a CRF value of 20 which will result in a high quality output. Default value is 23. A lower value is a higher quality. Use the highest value that gives an acceptable quality.
#    -c:a aac selects the audio encoder aac, which is the built-in FFmpeg AAC encoder.
#    -b:a 160k encodes the audio with a bitrate of 160k.
#    -vf format=yuv420p chooses YUV 4:2:0 chroma-subsampling which is recommended for H.264 compatibility.

/**
 * Implements the "throttle first" mechanism for click listeners, to prevent double taps.
 *
 * How it works:
 * - Define a sampling window time (default: 500ms)
 * - when you click at time T0, the first click gets dispatched and the subsequent ones happening
 *   between T0 and T0 + WindowTime gets ignored
