Content Creation

• Adding file(s) to published items causes an error.  A work around is to unpublish the item, add the file(s), and then republish the item.

• An Avalon item is created every time you choose the Create menu even if you do not associate any media or metadata with the item.  These Avalon items will only be viewable by Collection Staff because they receive access status of "Collection Staff Only" by default.  Avalon items can be deleted individually. 

• Items can be published without adding any media to them.  To keep them hidden, edit the item and then, on the Preview page, click Unpublish at the top of the item.
  
  
• Long section titles can cause Avalon to throw an exception. To work around this problem keep section titles shorter than 32 characters.
  
  
• Content in the batch ingest file is case sensitive. Be sure not to mix case as this might case problems with the ingest process
  
  
• Section labels are limited to 255 UTF-8 characters

Delayed Job

• In some versions of Delayed Job, a process can go out of control and hog resources. Here are instructions for restarting delayed job.

Skip Transcoding

• When streaming using Adobe Media Server, skip transcoding MP3s don't process correctly or playback.

File Management

• When using skip transcoding for single or multiple derivatives, Avalon's master file management setting is applied to the highest quality derivative (or single) only. This means that if your application is set to move files to another location (removing them also from the dropbox) then only the highest quality derivative is affected - leaving other two in place.

Group Management

• The Manage Groups interface will allow the creation of a group name with embedded (blank) spaces, but sometimes members of that group will not have access to items in the collection. Solution: For now, don't create groups with spaces in the name–use hyphens or underscores.
  
  
• In the Manage Groups interface it is possible for members of group_managers to delete any Ad Hoc groups even if they are not the group creator. If you do try to delete these groups, you will receive a delete confirmation message.
  
  
• Renaming a group may remove permissions from collections and items. To fix this problem be sure to reapply any exceptions after the group has been renamed.

Playback 

• If you are using Internet Explorer 9, the quality buttons in the quality menu are not available.
  
  
• For video navigation and playback of structured segments, links jump to the closest previous keyframe boundary (keyframes are every two seconds for any Avalon transcoded materials) which can result in the previous structure link being played and highlighted until the player catches up to the correct time offset.  

• If you are using the AMS streaming server on any desktop platform - from a paused player state, clicking the first segment link (only after a later time offset is selected) does not register. You must click it twice for it to register the correct time offset. This is an issue with RTMP playback on AMS and will be addressed in Release 5. 
  
  
• If you are using the Red5 streaming server on any desktop platform, the player will not update to a current still image in pause mode. It will display the poster image instead. 
  
  
• If you are using an Android device with any server, seeking prior to playback does not update the still image on your video, but it will display the poster image and play from the selected time. 
  
  
• If you are using an iPhone - any seeking via structure in the page view will not reflect the current frame but displays the video's poster image. This will not affect the playback from starting at a specific time.   
  
  
• Android (all streaming servers) - when navigating timeline via structure links or via the scrubber - Android seeks to HLS segment start instead of time offset and creates strange navigation/playback experiences. It's usually a few seconds off.
  
  

• The poster images may have a strange aspect ratio when in full screen mode. This does not affect video playback which retains the correction dimensions.
  
  

• Mobile streaming may not always work.  For the fix see Restoring mobile playback in Avalon 4.0.1 (VOV-4081) 

Player Embedding

• If you are using Internet Explorer 9 or 10, the embedded player will not go full screen.
• Avalon uses iframes for video embedding. Embedding should work with sites that support iframes. 
•  For embedded Avalon media to play in Safari, you have to go to Preferences -> Advanced and UNcheck "Stop plugins to save power"

Batches

• If you have a batch with large files added to the dropbox, the batch may fail while the files are being copied.  If that happens, once batch ingest package is completely copied over, delete the error file in the dropbox and the batch will be begin processing again.

System configurations

• Uploading a file larger than the value configured in the Master File model will throw an exception instead of being gracefully handled. If routinely uploading files bigger than the default either change it or use the dropbox interface.

Audio Ingest

• There was a typo in matterhorn's config file etc/encoding/avalon.properites. Go to your matterhorn's etc/encoding directory and run the following:

  wget https://raw.githubusercontent.com/avalonmediasystem/avalon-felix/release/3.3.0/etc/encoding/avalon.properties -O avalon.properties

  No restart is needed.
