Glitch with the webm video when seeking to a particular time.

[nirmitleo]

Hi Team ... 

While seeking a webm there is a strange glitch that happens consistently (replication steps can be found in the attached video: webm-glitch-pixiv6-compressed.mp4). This same glitch does not happen if let the video play undisturbed (i.e. without seeking to random points in time) which rules out the possiblity of the video being corrupt.

What are the things that I tried: 

1. I tried to see if the previous versions of PIXI (namely v5) had the issue, and surely they did. 
2. I tried to apply the pixi-patch from the following links, but they didn't work - 
   1. https://github.com/pixijs/pixi.js/issues/3526
   2. https://github.com/pixijs/pixi.js/issues/408

The problem seems to be there in multiple versions of PIXI: 

• PIXI v6.0.2: https://jsfiddle.net/zodiacleo/spgzy4x3/17/
• PIXI v5.3.3: https://jsfiddle.net/zodiacleo/dbhf2xu9/17/

SpectorJS trace has been attached (file: webm-glitch-spector-error.json)

 

Please let me know if I can provide more information on this.

Good detalization, that's better for issue/discussion in pixijs github.
