There was recently a discussion about this setting on the libreplanet-discuss list. ​https://lists.gnu.org/archive/html/libreplanet-discuss/2021-05/msg00013.html

I see there was an issue about it 9 years ago. https://issues.mediagoblin.org/ticket/375#no2

The issue suggests using preload="metadata" instead.

These are the two commands I used to find it:

git clone --branch v0.11.0 --depth 1 ​https://git.savannah.gnu.org/git/mediagoblin.git grep -R 'preload="auto"' mediagoblin/

mediagoblin/mediagoblin/plugins/archivalook/templates/archivalook/feature_displays/video_primary.html: preload="auto" class="video-js vjs-default-skin"> mediagoblin/mediagoblin/plugins/archivalook/templates/archivalook/feature_displays/video_secondary.html: preload="auto" class="video-js vjs-default-skin"> mediagoblin/mediagoblin/templates/mediagoblin/media_displays/video.html: preload="auto" class="video-js vjs-default-skin" id="video_1">

Prior to upgrading to MG 0.6dev, video media pages displayed large videos within a pane of 660x336 (this size apparently specified in the file mediagoblin/static/css/vjs-mg-skin.css). Now, however, the video media player is sized to match the original dimensions of the video, and it covers up most of the info panel on the right side of the page.

Example: (an 800x600 video) ​http://barn.kerosenecow.net/u/saul/m/perspective-grid-7db6/

Hello everyone,

I have initialized a new instance on ​https://medya.oyd.org.tr and want to serve our conference's ([ozgurkon.org]) videos and slides from it; but when I tried to upload videos, it's not working.

First of all, I just added video media type and uploaded a demo video, but it stuck on "Processing" step. Then, I changed my mediagoblin.ini like this:

[[mediagoblin.media_types.video]]
available_resolutions = 144p,240p,360p,480p,720p,1080p
default_resolution = 1080p
[[[skip_transcode]]]
mime_types = video/webm, video/ogg, video/mp4, audio/ogg, application/ogg, application/x-annodex
container_formats = Matroska, Ogg, ISO MP4/M4A 
video_codecs = VP8 video, VP9 video, Theora, H.264, H.264 / AVC, MPEG-4 video
audio_codecs = Vorbis, MPEG-4 AAC audio
dimensions_match = false

But nothing changed. But I wanted to add media via {{{bin/gmg addmedia}} because I want to add ~20 GB of video. If I use this tool, video will appear on the site, but Video.js is not working and <source> tag is not exist on <video> block.

If I tried to reprocess a video that I uploaded via web with {{{bin/gmg reprocess}} I got this error:

WARNING:mediagoblin.processing:No idea what happened here, but it failed: TypeError("main_task() got multiple values for argument 'medium_size'",)

TypeError: main_task() got multiple values for argument 'medium_size'

I need to serve this videos, what should I do?
