FV Player 8

Yes, the switch from FV Player 7 to FV Player 8 is easy. All the settings and videos will stay. If you already have the FV Player Pro license with active support and updates, then you will get FV Player Pro 8 automatically.

The main changes in FV Player 8 are:

• new mobile controls
• new editor
• autoplay works with browser viewport
• storing user video positions in a separate database table
• security improvements

This should be related to your video format or mime type issues. Each browser supports different video format, MP4 is the recommended format. In general, it's recommended to use constant frame rate. Detailed instructions about video encoding for HTML 5. Please note that MP4 is just a container, it might contain various streams for audio and video. You should check what audio and video stream are you using. Read next question to find out how.

The video checker works automatically when you're logged in as admin. You'll see a text in upper left corner of any video on your site. All the necessary info can be found in this guide.

1. This can happen if your site is at www.domain.com, but the CSS is loaded from your CDN at cdn.domain.com. Based on CSS3 and HTML5 specs not all the resources can be shared between domains.

1. Second cause might be that your webfonts are served with bad mimetype

This means that the video information (such as what codecs are used) is not stored at the beginning of the file. Over they years web browsers got better at playing MP4 videos with bad metadata position, but they can still fail on iPhones. In general we recommend you to re-encode your video as per our instructions. If you have Quick Time Pro, just open the video and in the Movie Properties -> Video Track -> Other Settings turn on the "Cache (hint)" - screenshot. There are also server-side tools for fixing of this written in Python and there is even one for PHP, but it fails on videos bigger than the PHP memory limit. If you are looking for fast and efficient workflow for getting videos up on your website properly encoded and delivered to your end users, we recommend FV Coconut which integrates DigitalOcean Spaces and Coconut.co video encoding into FV Player. The videos are uploaded right in your admin dashboard when posting your articles.

Please check with your technical support if your web server supports HTTP range requests. Most of the modern web servers support this feature (Apache, Nginx, Lighttpd, Litespeed...). It's important for fast seeking in HTML5 video playback. Other possible cause is that you are using some membership plugin to protect downloading of your videos (Premise and others). While this might seem like a good solution, we don't recommend it as it increases the load of your server and it won't allow seeking in the videos. You can use Amazon S3 with privacy settings, just hit the link to read our illustrated guide.

We heard about problems when using some fancy pro templates like OptimizePress (read below for fixing instructions) or Gantry framework. These templates often break the WordPress conventions (probably as they often try to add too many non-template functions, like video support built-in into the template). We can debug the issues for you, just head over to our website and order the pro support. Full list of conflicting plugins is available here: https://foliovision.com/player/compatibility

Go to plugin Settings screen and hit "Check template" button. It will check if both jQuery library and FV Player JavaScript is loading properly. Also, check "I'm using OptimizePress template" question above.

Please check if these issues also appear when using the default WordPress template. There seems to be some sort of conflict between the FV Player CSS and your theme CSS.

Are you using some old lightbox plugin like http://www.4mj.it/slimbox-wordpress-plugin/ ? Or are you putting the video into Iframe? Also, the video should not be placed in an HTML element with lowered z-index.

Just copy the plugin into wp-content/plugins and then activate it on each blog where you want to use it.

1. Check your hosting for download speed.
2. Check your video encoding to find ballance of video quality and bitrare.
3. If you are looking for fast and efficient workflow for getting videos up on your website properly encoded and delivered to your end users, we recommend FV Coconut which integrates DigitalOcean Spaces and Coconut.co video encoding into FV Player. The videos are uploaded right in your admin dashboard when posting your articles.

The problem is probably in AdBlock. If it's active, the overlay ads will be blocked. Once AdBlock is deactivated for the particular domain where the video is played, the overlay ads will be displayed (page refresh needed).
