Xibo

Xibo start to play the video which is not fully downloaded from the server.

Asked by t4ol1n

the xibo client starts to play the video after downloaded the layout files .. but the video is not fully downloaded from the server. It then will search and try to download the other files. after finished downloaded all the files and compared the server side MD5 and local MD5, it will download the first file again. is there any way to guaranty the video is fully downloadded when the first time themedia player start to play the video .

Which server and client versions are you using? It sounds to me like you have an incompatible mix of versions.

the server side versino 1.2rc
client side is using .net version 1.0.7

the error message is that ...

FileCollector.xmdsFile_GetFileComplete(), Error Message is: Unhanded Exception when processing getFile response: the process can not access the file "filepath/x.mpg" because it is being used by another process..

then the process will skip the downloading and play this partial video file ..

Has that file completed downloading previously, then you've deleted it
from the local library on the client?

To prevent massively long startup times with large numbers of files the
client remembers that it has at one point correctly downloaded that file
and doesn't expect you to then delete it from under it.

If you want to clear the local library then you need to stop the client,
clear its contents and then clear the file cache too.

alex, thank you for your advice.

acctually the situation is that ..

i have cleared all the contents inside the xibo library.. then i started the xibo client application, after xibo client successfully downloaded the layout file and was starting to download the video file, this "SignalElapsedEvent()" is triggered and the media player was loading the video file and starting to play .. at this point the error "Unhanded Exception when processing getFile response: the process can not access the file "filepath/x.mpg" because it is being used by another process" is shown.. The downloading process is stopped...

after the other video files are successfully downloaded, this CompareAndCollect() method is triggered to verify all the MD5 from the file list. it will delete the partial file and download it again ..

i think this problem is always been there as if the media player is trying to load the file but the file is still in the downloading process, the downloading process will be stopped. is there any way to "Lock" the file until it is fully downloaded?

If the file isn't in the md5 cache then this can never happen.

As i said before if you're going to empty the library directory then you need to remove the checksum cache too.

It lives in application data/ local settings/ xibo

what do you mean by remove the MD5 cache, i have deleted the cacheManager.xml file from the appData.. but it works as the same...

Strange. Can you describe exactly the layouts you have scheduled so I can try and recreate this.

Better still please email over the xlf files for these layouts to <email address hidden>. please also send the contents of the cache manager xml file.

Also please confirm these are unmodified client/ server code bases.

Cheers

Alex, are You sure about that deleting cache manager is nessessary in normal usage?
As far i know cached record is considered valid if file exists in library and filesize and last modification date is same that one recorded in cache manager.
I don't need to delete cache manager when removing file from lib, and as far I remember it was designed like that after discussion with You and Dan. Or maybe some part of that plan is unimplemented? :)
So any file manipulation should be detected by cache manager, with exception of modifying data file inside and preserving modification date.

I'm as sure as I can be without reading through the code myself and checking. I discussed this problem though with Dan at length this evening and we simply can't reproduce it here at all. This is the only hypothesis we can come up with that might explain it.

I've managed to recreate similat situation, and i'm sorry to say that was quite easy:

Layout with three files,
On third file i've opened file in nonlock mode during transfer, so xibo was able to keep downloading file.
Correctly detected later by md5 and redownloading started.
During second try i've opened in notepad to create lock and got same error as above.
After downloading client started playback of default layout without calling md5 compare on last file.

So when cathing file write error checking md5 was somehow missed (unhandled exception in polish is same that english above):

But surely deliberately preventing the client writing the file to disk is very different from the behavior the op described where adding a new file causes the new version layout to run without the new media having been downloaded first?

Bartek posted a new comment:
I've managed to recreate similat situation, and i'm sorry to say that
was quite easy:

Layout with three files,
On third file i've opened file in nonlock mode during transfer, so xibo was able to keep downloading file.
Correctly detected later by md5 and redownloading started.
During second try i've opened in notepad to create lock and got same error as above.
After downloading client started playback of default layout without calling md5 compare on last file.

So when cathing file write error checking md5 was somehow missed
(unhandled exception in polish is same that english above):

I've focused on subject part - why file is even played when it was never downloaded correctly.

Maybe reason is differrent in both situations (file locked becouse some other reason), but effect probably same: file is locked during (re)download, exception is raised, damaged file is played becouse md5 check was omitted.

Bartek (czajka) said : 		#14

So we don't know why downloading is interrupted (maybe fs is damaged - chkdsk??, some antivirus locks it etc), but we know why xibo tries to play file, and it's looks like no fault in cache manager becouse it's not even called in that situation.

Dan Garner (dangarner) said : 		#15

What we are actually saying here is that when a file is downloaded by Xibo
it should always be removed from the cache manager first.

I.e. when the file is deleted, it should also be removed from the cache
manager - I thought it already did this. I will have to look through the
code later to be sure.

Hi,

We have a similar problem, but we know why: Our administrator modified directly the file in conflict on Library folder (server side), then when Xibo compare hashes, they are differents. Delete and upload the file on admin interface resolved the problem.

Here is part of my log:

HardwareKey: [IN]
HardwareKey: [OUT]
