Reading an EBML variable-length integer
View readVariableInt.js
/**
* Read an EBML tag header or length and return their respective values into
* single numbers.
*
* @example
* var tagHeader = new Uint8Array([0x1A, 0x45, 0xDF, 0xA3, 0x01, 0x00, 0x00,
* 0x00, 0x00, 0x00, 0x00, 0x1F]);
* var tagId = readVariableInt(tagHeader, 4, 0);
* console.log('The current tag ID is: ', tagId.value, ', skipping ', tagId.size, ' bytes.');
* // The current tag ID is: 172351395, skipping 4 bytes.

1. encode multiple bitrates with keyframe alignment:
ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
-g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4
My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.
