The V3 approach obliterates this race condition by hooking addSourceBuffer at the MediaSource.prototype level, I intercept the creation of every SourceBuffer. The moment a buffer is created and returned, I immediately install a hooked appendBuffer directly on that specific instance; before any page code can even see the instance, let alone cache a reference to its methods.

Arsenal tore Villa apart in a 4-1 win in late December and victories have been hard to come by in the new year – they have only won three of their last nine league games. Liverpool, Manchester United and Chelsea are still below them in the table but the gap is narrowing. With games against United and Chelsea coming in March, the top-three spot Villa have occupied since they beat Wolves in late November suddenly looks in jeopardy. So does their place in the Champions League next season.。业内人士推荐快连下载安装作为进阶阅读
