Lightroom 6.2.1: Video Cache is out of control
I recently upgraded to Lightroom 6.2.1 So far there has been a lot of fuss over the import dialog... ok, well sure, it has a few issues, but they can be either worked around or just revert back to 6.1.1
I would like to report and ACTUAL bug in 6.2.1
My D drive recently ran out of space... I tried deleting some stuff I didn't need, but still it kept running out of space... So I finally ran windirstat and had a look at it.. Nearly HALF of my drive was FULL of D:/temp/Adobe Local/Lightroom/caches/video/media Cache Files. Now here's the kicker... NONE of these video files are even on the hard drive that has my catalog on it. My lightroom database is on drive L:\ all my lightroom photos and very few lightroom videos are all on L:\ I have a few scans on drive K:\ that I import to lightroom... but these videos are ALL on Drives E:\ and F:\
here's another thing.. I knew Adobe wasted space caching videos, and I do have a GOPRO and I record a little video,.. .VERY LITTLE, maybe 1 video a year... so I don't really want ANY of the video cached.. I will wait for it to load... SO a long time ago, I set my video cache in Preferences>File Handling to the minimum of 1GB (It's was always a BUG to not allow 0GB) I don't want to cache any videos!!!!!!!!!! but here it is.. NEW BUG It's STILL SET TO 1GB!!!!!!!!!!! How is it gobbling up almost 1TB of space when I have it set to 1GB??????????????? So.... here's another problem... I have Cache files that are 4GB for a movie that only takes up 2GB on my hard drive.. what's up with THAT??????????????? I randomly checked a few, and the worst one was a 5GB cache file for a movie that only takes up 750MB on my hard drive... two things, first of all... you NEVER EVER EVER need to cache an entire movie... caching more than 1 minute of a video is useless... if you're going to watch the video in lightroom, it can just play the video on the hard drive fast enough that it doesn't need further caching.. second... DON'T CACHE THE VIDEO AT ALL!!!! just capture the thumbnail of it so you don't have a blank square on the catalog and call it a day... if someone wants to play the video, it will load and play plenty fast enough, Lightroom Can't work with video files, only play them, so WHY BOTHER TO CACHE THE WHOLE THING?? come on Adobe, some COMMON SENSE please!!!!
so now ANOTHER BUG, it's already set to limit video cache to 1GB, so I figure, the new import thing must have built this RIDICULOUS Cache, so I will just Purge it, that will bring it down to 1GB right??/ WRONG!!! It pops up a message saying "Video cache is being purged, this message will be dismissed when the purge is finished... I wait 5 Seconds, and the message disappears, I have NO hard drive activity, and well... I STILL have 1GB of Video Cache files!!!!!!!!!!! Ok, maybe it didn't take.. let me set it to 2GB, then purge.. NOPE! let me set it back to 1GB then purge, NOPE..
ok, so I suspect how to fix it will be, (I Hope) click import, and select the movies folder and then select Ignore source... by the way, how do I add my E:\scans folder as a legitimate source.. I just removed a source, how do I add a nice shortcut button for a new one? ok, now that source is removed, I hope it won't scan it again... now that it will HOPEFULLY not scan that hard drive again, I'll manually delete the offending Video cache.. ok manual delete complete, Ahh my drive can breathe again.. Lets open light room and see what happens.... ok.. open.. lets open the Import dialog because eventually I'll need to import something... oh-o..... What's this??? Scanning Common Locations... OH-NO!!!!!!!!!! first of all E:\Moves and F:\TV are NOT COMMON LOCATIONS FOR PHOTOS Second, I REMOVED THOSE LOCATIONS.. It has a valid location listed, WHY IS IS LOOKING FOR SOMEWHERE ELSE????? Yes it's now scanning VIDEOS and the only reason for it to be taking so long is it went back to my E and F drive... lets look at the cache folder... oh yes, MediaCache already has 3,876 files in it.... not looking very good. Why is it caching files that are not even imported into lightroom??? and why is the cache for each file taking up more space than the entire video??? If you want to make a video cache.. just cache the THUMBNAIL ONLY!!!!! we don't need or want anything else cached.. a thumbnail is all we need cached for our few relevant videos so we don't have a black square in our catalog.
Crap, I'm going to be FORCED to revert to 6.1.1 even though I had every intention of working around the other 6.2.1 issues. TEST TEST TEST Test your software!!! the monkeys you have testing it are not doing a good enough job! send it to me, I'll test it for you, It needs to be tested on a real computer, one that is used for other things.. that way you would KNOW it's finding stupid things like CD cover art and every movie and tv show on my hard drive. I seem to find glaringly obvious issues within one day of using the product. I've been developing software for the last 28 years, I know how it should be done, and how things should be tested, and this is NOT being done AT ALL. Your programmers are sub-standard and are missing the mark, and your non-existent SQA department is NOT testing even the simplest of functions.

Last night I checked the video media cache, it was 576MB, which I feel is acceptable given the 1GB limit I have set. I left lightroom open all night in the library module, and then checked the cache, it was still 576MB, and I also checked the video media cache files themselves, they all were all either gopro or cell phone videos that were actually included in my catalog. So thats good news... but to try to find where the problem is... I opened the import, just left it open on the initial screen on v6.2.1 of lightroom, and after working on other things for 2 hours, I've come back to check on it... now, my cache is 1.6GB... oh o, thats a problem, it's ignoring the 1GB limit.

I went straight to 6.2.2, So I can't say if any other versions are doing this.
I still have 6.2.2 installed, I left it specifically so I could help provide information to you on this issue.
The current status of my D:\temp\Adobe Local\Lightroom\Caches\Video\Media Cache Files folder is 182 items totaling 3.05GB. MY MAX Video cache size is set to 1GB still, so it is currently 3x larger than it should be. I am happy to report that all of the cached videos are either from my gopro or my cell phone, and they all do exist within my lightroom catalog, however, I have not accessed any of the videos or even looked at the thumbnails for them, so I don't know why they are cached.
While I'm not thrilled that my setting of a 1GB limit is being ignored, It's at least not filling my hard drive with 900+GB of video cache files. The problem here is, I can't tell you if this particular behavior was happening on 6.1.1 or not. it would seem that the video cache filling my hard drive with a cached copy of every single video on my system, even on drives with nothing to do with lightroom was a one time event... I would be happy to uninstall lightroom, and re-install version 6.1.1 then leave it for a few days, and report on the status of the video cache, then upgrade to 6.2.2 and see if it again attempts to fill my drive with video cache files.
I really feel that with SSD's becoming so popular, and with that, people are sensitive to excessive activity on their C: drive, It would be very beneficial to allow an option to disable video caching altogether, I personally see no benefit to the video cache whatsoever, and would rather wait for a video to load should I choose to play it in lightroom, I suggest still capturing the preview and displaying that, so there aren't black squares, but to cache the video and create a file that is larger than the original video is just a waste of activity on my drive. I happened to move my temp folders to another drive, but most people don't do that.
For another suggestion, with modern hardware, SSDs and SATA III hard drives, It's quite possible and likely that caching of files on such systems is completely obsolete now. Even my mechanical hard drives are blazing fast. It may be time to allow the disabling of the camera raw cache as well... The cache may end up actually slowing things down.
you could allow 0 for both caches, and if this would hurt performance on some systems, put a warning that disabling the cache could cause some systems to perform poorly, but then allow the user to make the setting as they wish... Similar to the virtual memory paging file, which I have had disabled for years with a quite noticeable increase in performance. It's simply not needed anymore, but if it exists, it slows things down. I have 64GB of physical RAM, why would I need any virtual memory??.... So... My hard drive's and read access is BLAZING fast, why would I need or want to cache my files?

I uninstalled Lightroom, and re-installed version 6.0
First I notice that when I just open a catalog, and even go look at a few videos, my video cache file (which is now located at C:\Users\James\AppData\Local\Adobe\Lightroom\Caches\Video\Media Cache Files) is very small, just a few hundred MB, I even played a video, and still, it's nice and small. So, to be thorough, I thought I would try a few different things, such as selecting my entire catalog and scrolling through the entire thing, this did not affect teh video cache, so next I tried going to import... just for the fun of it, I selected my E drive, which is full of nearly 4TB of movies and TV shows, I let it show about a screen worth of video files, then closed the import dialog, about 10 seconds worth, and during that 10 seconds, my video cache has jumped to 11.5 GB, and the cached files are ALL the movies that were in that folder, and on top of that, the cache files are HUGE, for example, I have a file named "some tvshow title.avi 48000.cfa" and it's size is 504MB, however the original "E:\TV\some folder\some tvshow title.avi" from which this was cached, is only 235MB.. that's some effecient cache you have there....
So, the next, most obvious thing to test, is to purge the video cache. So I went to preferences and pushed the purge cache button in the file handling section.. it did reduce the size of the cache, but it didn't clear it. So I closed lightroom, then re-opened it. Next I went to purge the video cache once again.. It put up a message saying The Video Cache is being Purged, this message will be dismissed when the purge is finished. After the message remained for 15 minutes, I wondered what was up.. so I went to check on my video cache to see it's progress, and WOW my Video cache is NOW 32GB!!!!! I went to check on some files and I have a LOT of files over 1GB - 1.8GB in size.. EACH, and the corresponding files which were cached were only 500-700 each. In the time it took me to look over these files, my video cached has jumped to 46GB!!!!!!!!!!!!!!!!!!! So i hit cancel. the box now says cancelling... it has said canelling for the last 20 minutes, and while the cache is still at 46GB, I don't understand what's taking it so long to cancel.
please note, this is a real bug, This test is repeatable, I've tried it on my laptop and my desktop.
So this is a MAJOR BUG with version 6.0, With 6.0, I needed to select a multimedia drive and breifely let it display some of the videos.. that was the trigger, but once this folder was cached, even though I NEVER IMPORTED ANYTHING FROM IT, the cache has run away with it, and it appears the purge function caused the runaway situation.
This has appearantly been made worse by the new import dialog, because it filled my drive until there was no more space with this rediculous cache, and furthermore, I did not ever select any of my hard drives with movies and tv shows to import from.... it did it by itself.
I think I have enough information from version 6.0, I will upgrade it to version 6.1.1 and see what the results are.

Ok, I terminated lightroom.. rebooted my system. restarted lightroom. went to purge video files, it took about 3 seconds and was done.. checked the cache, it was empty, 0 bytes, 0 files.
I'm still on 6.0
Lets try to figure out what is happening here...
just leave lightroom open 10 minutes... no change to video cache...
click Import, select a drive with videos on it.. it starts the insane caching... cancel the import....
do nothing.... just leave light room open, in library module Video cache continues to grow...
close lightroom... do nothing with computer
lightroom video cache continues to grow!!! LIGHTROOM IS CLOSED!!!!
do nothing some more
lightroom video cache IS STILL GROWING!!
look at task manager... lightroom is not there
sort by processor % used
there is something called dynamiclinkedmediaserver.exe using 13% of my processor... but lightroom is closed, and i never actually imported anything
i terminate the dynamiclinkedmediaserver.exe and finally my video cache stops growing.. I have very fast drives and a very fast computer, so it managed to get to 48GB in the short time I figured this out.
YOU HAVE NO BUSINESS CACHING ANYTHING DURING IMPORT, ESPECIALLY FILES THAT ARE NEVER IMPORTED!
