vpaid for jw7

Hi, I'm using jw6

Recently my ad provider email me that Sept. 1st firefox and google chrome going to launch an update to disable flash media automatically displaying content. So they recommend me that I need to make my player html5 compatible and verify that VAST/VPAID ad renderer for my media player is compliant with JavaScript VPAID protocols then ensure my video assets are encoded to html5 friendly formats (e.g., MP4)

I'm wondering if jw7 ad will do the job that they are asking for.

Hi, there!

There is a lot of misinformation spreading about Chrome and Firefox blocking all Flash content from automatically playing. It is true that they are throttling or blocking some content, but not all. They are only automatically blocking content that is less than 400px wide by 300px tall, which is an uncommon size for most video player embeds.

It is a good idea, however, to try to make all of your content as HTML5-friendly as possible, as that is the format that is the most cross-browser and cross-platform compatible. However, if you have to display Flash content, you can still do so, but we recommend specifying a fallback stream that is either MPEG-DASH, HLS or MP4 compatible.

As for ads, as I said, you should be OK as long as you’re Flash-based content is 400px x 300px or larger, but we do recommend the following:

1. Remove any settings that force Flash to primary and set up the player with HTML5 first video files.
2. Work with your ad partner to ensure you get HTML5-compatible creatives (mp4s, VPAID 2.0 JS).

JW Player will be adding support for VPAID 2.0 JavaScript creatives before the end of Q3. If you have any sample ads, please send them to so we can guarantee them working at launch.

In summary:

- For now, if your video player is larger than 400px wide and 300px you have nothing to worry about.

- If your site uses Flash videos that are less than 400×300, Chrome and Firefox will likely throttle video playback or block the videos altogether.

- The only way to truly ensure that video playback is not blocked by the browser is to use media formats that do not require Flash. This might take a while as the streaming media landscape shifts from HLS to MPEG-DASH.

- If you are running video in a sidebar and thus need to have smaller video players, make sure the media and ad format will always render in HTML5. Since these video players are small, they likely do not need to take advantage of streaming and can run fine with just an mp4.
