Issue Windows Player

[Didi3333]

Hi,

First of all thank you very much for this dev.

I'm faced an issue when i make a record of more than 3 seconds.

On Chrome, and VLC there are no impact but with the classic windows player Movie and TV the video doesn't displayed until the end

Analysing the webm with ffpmeg, it seems there is an error on a data:

The emplacement change on different record that i made. I also check with classic recorder without the fix and there is no error detected by FFmpeg.

Have you got an idea ?

I'll take a look. Also, if you can attach a file example (before the fix), it will help.

Hi,

Here the webm without the fix. I put in into a zip due to Github limitation

test_WithoutFix.zip

Hi @yusitnikov, had you find time to check the file ?

Another repro example is: https://nickdesaulniers.github.io/netfix/demo/bufferAll.html (mentioned in the MDN docs).

After doing some research, it turns out that in order to implement this properly, the EBML header not only requires the Duration metadata but also requires adjusting the SeekHead and Cues metadata too.

I've got a working version here for reference, but feel free to trace that all the way back to the ts-ebml package's makeMetadataSeekable() function, which is where all the magic happens.
