webtorrent.min.js:7 Uncaught TypeError: Cannot read property 'readUInt8' of undefined

[Wasser-Eis]

• WebTorrent version: v0.90.0
• Browser name/version (if using WebTorrent in the browser): Google Chrome 49.0.2623.110 m

I once again try to use client.appendTo(....) to get mp4 videos played back in the browser. This worked for this MP4 file: http://www.w3schools.com/html/mov_bbb.mp4

But if I use the same code with this MP4 file: http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_2160p_30fps_normal.mp4

, I get the following error:
"webtorrent.min.js:7 Uncaught TypeError: Cannot read property 'readUInt8' of undefined"

Thanks for reporting this, but it actually looks like a bug in videostream, or one of it's dependencies.

@jhiesey - can you confirm?

Here's a full stack trace:

@feross: This should fix the exception: jhiesey/mp4-box-encoding@9a9c7c3

However, this file still doesn't work even with that fix, so I'll keep investigating.

Yeah, chrome MediaSource doesn't seem to like the audio mime type of audio/mp4; codecs="mp4a.6b" on the audio track. This could either be a limitation of the browser or a bug in computing the mime type in a dependency of videostream. I'll look at this soon.

@jhiesey Cool, thanks for digging into this 👍
