Hi,

FYI:

just installed 1.34.3 for Centos8
Followed the readme and all seemed to work fine but:

When I tried to "download video" from "Events" it prepared the ZIP and downloaded the file,
the file seemed to be "empty", 1kb of download.
it created a zmExport_XXXXX.zip with named folder inside and a zmFileList.txt:
/var/lib/zoneminder/temp/zmExport_41059/zmFileList.txt
it also includes a numebered folder which was empty.

after reading the web instructions I found out that ffmpeg is recommended and should be enabled
I checked the "Options" and "Images"->OPT_FFMPEG and PATH_FFMPEG which both were correct set
I checked that I had the ffmpeg installed and it was.

Unchecking the OPT_FFMPEG box, saving and rechecking and saving seems to have fixed the issue but only for new events.
old events still dont work

I've tried to delete the contents of the "zoneminder/temp" folder with no luck
the "temp"-folder contains no videoes/images for the "empty" files downloaded:
bolds are the empty and correct files created:
/var/lib/zoneminder/temp/
total 19232

tried different internet browsers

"export" does work for both old and new events

PS: "download video" as "tar" results in "Export Failed" message

The system:
latest minimal installation of Centos8.1 as of per 2020-03-05 (+1 CET)

I'm watching this with interest. I am a newbie and have installed 1.34.5, I can export video to TAR, but not ZIO. My ZIP export also come up empty

Try to disable and enable the ffmpeg settings as mentioned in the post

Unchecking the OPT_FFMPEG box, saving and rechecking and saving seems to have fixed the issue but only for new events.

Yes I ahve tried that.

ffmpeg is not involved in export.

Export just copies(hard links if possible) the event data to a tmp dir structure and zips or tars it up with a few html pages for viewing.
So if your zip or tar has empty directories then there must have been a failure copying the event files.

There will be logs. LOOK at them, and post them here.

I tested, and this works fine for me on ubuntu, so it is going to take some investigation.

Thank you, I have just tried a few times again. This time TAR is not working either.

The errors in my log are:

something isn't right here, that for sure.
I upgraded to 1.34.5 yesterday, upgraded the database and all looked fine.

I'm testing for now but somehow "old/deleted" storage/monitor events just appear in the log:
I only have monitor ids 4 and 8 available but zoneminder logs about monitor 6, yesterday, it complained about a storage id which I had deleted.

my 2 monitors are split between 2 storages now, one default(/var/lib/zoneminder/events) and second is a sshfs-directory
both work fine but none of these want to work with "download video", either tar or zip, export does export but omits the video in the exported zip file.
it plays fine from events but does not download correct..

I've searched the logs but cannot find any clues, no errors about exporting at all:

Export works fine for me, problem I am having is with the html viewer, the iframe height is not set correctly. I have to manually change "height: 100%;" to "height: 850px;" on the TD's style, usually 130px more than the video height (720) and add "height: 100%;" to the iframe's style.

For now, I have been adding on the <script> section:
$(document).ready(function() { $('#myframe').parent().css("height", "850px"); $('#myframe').css("height", "100%"); } );

And playback is awful slow, I need to scroll through manually to see it. Still haven't played around with the speed yet...

Is this being looked at?

Thanks!

No it isn't.

We look forward to your pr.
