preview image for html5 video is not shown in frontend #7

Hi,

I wanted to include some videos and I added a preview_image for each video. The poster attribute with the image is not rendered, it's missing.

Can someone confirm this issue?

I use TYPO3 9.5.13 and the latest version of the hh_video_extender.

poster-attribute image is only shown if preload is set to "none": https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video#attr-poster

so you can now set "plugin.tx_hhvideoextender.settings.showAllwaysPreviewImageAsImage = 1" (or constants-editor) to have allways a preview image as an additional img-tag. So you can do what you want with it (with css and or js) :)

@medarob please try the new version 1.6 did this work for you?

I will test the new version. Thank you.

Additionally, there also seems to be a problem in Chrome with the poster-attribute. You have to set preload to "metadata" or "none" to make it work: https://support.google.com/chrome/thread/15245443?hl=en auto (which is now the default value in the extension) does not work in Chrome.

In Firefox all options seems to work, even if metadata seems to be the default option. The default value is different for each browser. The spec advises it to be set to metadata.

Can you change the default value to metadata because this seems to work in most browsers. Otherwise the user has to change the settings everytime from auto to metadata to make it work in Chrome.

You should be able to configure the default value by yourself if you need this: https://docs.typo3.org/m/typo3/reference-tsconfig/master/en-us/UserTsconfig/TcaDefaults.html :)

or with TCEMAIN like: TCEMAIN.table.sys_file_reference.preload = 2 // or something like that...

currently not `tested...
