As is standard, some configuration recommendations to get started with a more feature-full setup.

Enabled by adding the piwigo-videojs plugin, and then following the wiki. The files to edit are in the Docker image, which can be accessed via docker exec -it piwigo bash.

Enable uploading of videos and more permissive filenames, by editing /gallery/local/config/config.inc.php and changing a couple of configuration variables (edit using nano):

...
$conf['upload_form_all_types'] = true;
...
$conf['sync_chars_regex'] = '/^[a-zA-Z0-9-_., \[\]()]+$/';
...
$conf['show_exif_fields'] = array(
  'Make', // photo-related metadata
  'Model',
  'ExifVersion',
  'Software',
  'DateTimeOriginal',
  'FNumber',
  'ExposureBiasValue',
  'FILE;FileSize',
  'ExposureTime',
  'Flash',
  'ISOSpeedRatings',
  'FocalLength',
  'FocalLengthIn35mmFilm',
  'WhiteBalance',
  'ExposureMode',
  'MeteringMode',
  'ExposureProgram',
  'LightSource',
  'Contrast',
  'Saturation',
  'Sharpness',
  'bitrate', // video-related metadata
  'channel',
  'date_creation',
  'display_aspect_ratio',
  'duration',
  'filesize',
  'format',
  'formatprofile',
  'codecid',
  'frame_rate',
  'latitude',
  'longitude',
  'make',
  'model',
  'playtime_seconds',
  'sampling_rate',
  'type',
  'resolution',
  'rotation',
  );
...

This works well for the following file formats: mp4, ogg, webm. If using the LinuxServer Docker image, the required tools will have been included already.

• pwg_representative needs to be created in the same folder layer as the video, i.e. the media folder is no longer read-only and requires write permissions to generate video screenclips. Video playback itself still works, but there is no preview. See issues #97 and #152, with one user suggesting to manually add symbolic links instead as a workaround. Consider this answer for a more permanent solution...?
• Not ready for Piwigo 11:
  • Somehow after the first synchronization run, the form clears out and subsequently throws a null reference error in many PHP scripts. Commenting out the problematic part alleviates the symptoms, specifically the block mentioned below.

/*
// Merge default value with user configuration
if (isset($conf['vjs_sync']))
{
    $sync_options = array_merge(unserialize($conf['vjs_sync']), $sync_options);
}
 
if(isset($_POST['mediainfo']) && isset($_POST['ffmpeg'])) {
    // Override default value from the form
    $sync_options_form = array(
        'mediainfo'         => $_POST['mediainfo'],
        'ffmpeg'            => $_POST['ffmpeg'],
        ...
        'subcats_included'  => isset($_POST['subcats_included']),
    );
 
    // Merge default value with user configuration
    $sync_options = array_merge(unserialize($conf['vjs_sync']), $sync_options_form);
 
    // Update config to DB
    conf_update_param('vjs_sync', serialize($sync_options));
}
*/

This one is a no-brainer addition, otherwise you shall be consigned to manual page-switching.

Note however this scroll does not extend to albums, i.e. albums will still be paginated with at most 12 per page. Organize your content wisely.
