There needs to be a description somewhere of this problem, e.g. in a wiki page.
As I understand it, there are two buffers in MSE playback, one buffer is in browser memory and is filled from the network by the test calling XHR or fetch. The second buffer is the MSE source buffer. I understand the uncertainty around the size of the MSE source buffer but why doesn't the test keep filling the buffer in browser memory?
