    force AMA cache update for linked file

    hi Marianna,

    I discussed this separately with Dennis, but here is our question in more detail:

    We need a method to force update the AMA cache for linked files so that changes to the essence are reflected in MC timeline, but cannot find any such method in the SDK.

    At the moment, if eg my_file.mxf  (op1a) is linked and in the timeline and I make an essence insert to it, the audio and video shown in the timeline is still the original cached data. 

    Even re-linking the file does not fix this as it seems AMA views the metadata only and does not recognize a data change unless the UUID is changed, at which point it treats the asset as new and extracts new cached info.  Obviously changing the UUIDs at every update is not viable.

    Obviously this issue was resolved for Avid's own insert function for XAVC etc, so any help appreciated.

    I don't believe this to be a Link issue (AMA) as Link does not have a cache. This could be an issue with the FRAME CACHE. There is already a manual way to clear the frame cache, under SETTINGS > SITE > MEDIA CACHE > VIDEO MEMORY
