chrome pc flash小于400x300被认定为广告，block播放
i have a custom made flash video player that plays true video contents, not advertising.
if the video player is smaller than 400x300, chrome blocks autoplay, either, auto play will works.
is this by design?
My customer are asking me some explanation. There is official news about this from Google?
Thanks for posting. I believe Chrome did change how they run plugin content. When you go to Settings > Show advanced settings > Privacy > Content settings > scroll down to Plugins. The selection you want to choose is "Run all plugin content". It's by default set to "Detect and run important plugin content". This will allow Chrome to run the prominent plugin content on webpages, like the main content, but not secondary content. I think when your video is smaller than that size, Chrome determines it as secondary content which is why it won't autoplay. Give that a try and let me know how it goes.
