Most common video player error
如果你尝试在MathWorks.com上观看视频,and a gray box loads where you would expect to see the video player, please try clearing your browser cache and reloading the page. This should fix most of these issues. Some ad blocker and privacy browser extensions may also cause the player to not load correctly. If you think that may be the cause, please disable those extensions before clearing the cache and reloading the page. If you try these steps and the video still does not play, please submit the video feedback form (//www.tianjin-qmedu.com/programs/videos/video-feedback.html) and be sure to leave your contact info AND provide the URL of the video you're having problems with.

________
MEDIA_ERR_ABORTED
- Error code: 1
- Headline: The video download was cancelled
- Message: You aborted the media playbackPossible cause: A somewhat generic browser error that indicates that something stopped the video download process in its tracks. This could be:
o An issue with the computer, such as a crash or interruption to the network service
o A browser problem, or a configuration issue
o The browser is not supported, or currently lacks support for video
o A firewall, web proxy, or network issue is blocking the video download when the browser tries to play it
Steps to try and fix the problem:
o Refresh the page
o Try an alternative browser
o If using Internet Explorer, check the version of Flash installed in your browser. An easy way to check is to visit this website:
http://get.adobe.com/flashplayer/about/
o Flash is required for all versions of Internet Explorer except for Edge
________
MEDIA_ERR_NETWORK
· Error code: 2
· Headline: The video connection was lost, please confirm you're connected to the internet
· Message: A network error caused the media download to fail part-way
Possible cause:
o防火墙挡住了视频数据
o A web proxy interrupting the connection or filtering traffic
o Filtering software (such as Sophos, or Lightspeed Web Filter blocking content)
o A general network failure (for example, the internet connection to your home/school/personal computer fails)
Steps to try and fix the problem:
o Check that the internet is working correctly on the affected machine
o Refresh the page, which can restart a connection that may have dropped
o Try another video. Does that work? If not, the error suggests that content as a whole cannot be reached.
________
MEDIA_ERR_DECODE
· Error code: 3
· Headline: The video is bad or in a format that can't be played on your browser
· Message: The media playback was aborted due to a corruption problem or because the media used features your browser did not support
Possible cause: A browser being unable to play back the requested content. This can happen during playback, or more likely, at or toward the beginning.
Steps to try and fix the problem:
· If using Internet Explorer, check the version of Flash installed in your browser. An easy way to check is to visit this website:
http://get.adobe.com/flashplayer/about/
· Flash is required for all versions of Internet Explorer except for Edge
·Refresh the page, which may re-download a piece of content that failed to play back due to a partial download on the first try.
· Update your browser to the latest version. Chrome and Firefox should prompt you with updates, but it is useful to check.
________
MEDIA_ERR_SRC_NOT_SUPPORTED
· Error code: 4
· Headline: This video is either unavailable or not supported in this browser
· Message: The media could not be loaded, either because the server or network failed or because the format is not supported
Possible cause: A browser being unable to play back the requested content due to it being unavailable, or cannot be played in this particular browser. It differs from error 3 in that playback fails before it begins, rather than during playback.
Steps to try and fix the problem: Check the version of Flash installed in your browser. An easy way to check is to visit this website:
http://get.adobe.com/flashplayer/about/
The latest version of Flash is required for all versions of Internet Explorer except for Edge. If you are using Internet Explorer, it is essential that it is not running in “Compatibility” or “Enterprise” mode, and that the rendering mode is set to be the same version as the version actually running. Some versions of Internet Explorer will describe this as Edge mode—if you see that mode listed, that’s the correct one to choose. Having either of these set incorrectly may break playback, cause incorrect behavior, or prevent the player from working at all.
In most cases, both of these settings will be correct, but may have been specifically set by your IT team.
________
PLAYER_ERR_TIMEOUT
· Error code: -2
· Headline: Could not download the video
· Message: Could not download the video
The player is unable to play back content / buffers for 45 seconds
Possible cause:
o Insufficient bandwidth / network speed
o防火墙挡住了视频数据
o A web proxy interrupting the connection or filtering traffic
o Filtering software (such as Sophos, or Lightspeed Web Filter blocking content)
o A general network failure (for example, the internet connection to your home/school/personal computer fails)
o At times, it can be caused by player specific bugs
Steps to try and fix the problem:
o Check that the internet is working correctly on the affected machine
o Refresh the page, which can restart a connection that may have dropped
