Extra details

After reviewing error.log in lighttpd, here is the first error encountered
(mod_fastcgi.c.421) FastCGI-stderr: PHP message: PHP Warning: fopen(/var/www/rpicam/scheduleLog.txt): failed to open stream: Permission denied in /var/www/rpicam/config.php on line 66PHP message: PHP Warning: fwrite() expects parameter 1 to be resource, bool given in /var/www/rpicam/config.php on line 68PHP message: PHP Warning: fclose() expects parameter 1 to be resource, bool given in /var/www/rpicam/config.php on line 69PHP message: PHP Warning: fopen(/var/www/rpicam/scheduleLog.txt): failed to open stream: Permission denied in /var/www/rpicam/config.php on line 66PHP message: PHP Warning: fwrite() expects parameter 1 to be resource, bool given in /var/www/rpicam/config.php on line 68PHP message: PHP Warning: fclose() expects parameter 1 to be resource, bool given in /var/www/rpicam/config.php on line 69

Update : changing the permission of rpicam folder into www-data seems to fix the issue (chown -hR www-data:www-data), although I don't know if this the recommended way.

@arkhub
Permissions should be granted more targeted:

chown -R www-data:www-data /var/www/rpicam

Fixed: 503549e
Changelog: 2e41b6f

[dsalgueiro]

As-is V6.28.0 installation with ProFTP and RPI Cam Web Interface: Cannot view RPI Cam Web Interface page.

With chown -R www-data:www-data /var/www/rpicam

RPI Cam Web Interface now shows up and works

STILL NOT WORKING: 404 error when trying to download any recorded videos or Gzipped videos. Note that preview images do appear. I think this is another related permissions issue.

@dsalgueiro
Could you please paste:

ls -al /mnt/dietpi_userdata/rpicam

Omit any actual file names in case for your privacy, I am only interested in the user/modes of the contained files. The videos should be stored there and need to be readable by www-data user.

[dsalgueiro]

Here's what I get with that:

I previously deleted several motion triggered recordings and the video / downloads page only shows one video now. I am wondering if the web cam interface page also can't delete the actual recordings.

@dsalgueiro
Hmm the permissions look fine as www-data is owner of all files and has write access as such. Also strange that it shows one video only, as all present ones have exactly the same permissions. But the shown one is one of those listed in the directory, right?

Correct, the only video shown is in the top 2 files, first one is the video, second one is a thumbnail.

This is what shows up in the web browser navigation space that gives the 404 result:
http://10.0.0.44/rpicam/media/vi_0000_20200328_154902.mp4

---Wait a sec. The video file is supposed to be a .h264, not mp4.

When I navigate to
http://10.0.0.44/rpicam/media/vi_0000_20200328_154902.h264

I can download the video when I navigate to the .h264 extension.

Please also note that I can delete the videos from the web interface. I was wrong that the files didn't delete.

Update,

It's all working now.
