That's a tricky thing. Because any conversion involves doing a decode and encode. And if you observe any encoding algorithm, it uses transforms and many other steps, which give different o/p for different input streams. In plain words, the size depends on the complexity of raw video, so its not possible to predict the size effectively.
Given the length of a video, how do I calculate how much how much space it will take after conversion?
Pregunta
OK so I am making a video converter and whenever user inputs a video, I want to be able to tell the user how much space on the disc it is going to take after conversion.
I am using Xuggler
for the conversion task which is a wrapper around ffmpeg
. It lets me access the the total length of the video in milliseconds as a long
value.
Based on this, how can I calculate the size of the output video that will be generated ?
