When clicking on video, only sound is played

[kuzmos]

Video thumbnail is generated and displayed correctly when scrolling through photos and videos on the "Photos" page, but when I click on the video, only a gray transparent overlay is displayed with sound, but no picture. When I right-click on the video and select full-screen, it is played correctly. Is it maybe some css issue?

I have the same issue as well.

Same issue is happening while browsing on Firefox mobile on Android. A gray transparent rectangle overlay with sound and progress bar, but no video.

It works with my video files for firefox and chrome. What kind of video file is it?

[ErgoProxy1337]

same here. for me that are .mov files. While holding with the mouse over the video, I can see the video play but when clicking on it, I get only audio

[derneuere]

Yes, the previews get reencoded to be in the right format all of the time. Do you know which codec this file uses? You can find it with VLC: https://superuser.com/questions/348159/vlc-how-do-i-see-video-files-information-resolution-encoding-information-e/1226072

Mhm okey... h265 is hard...

[derneuere]

Do you have a h264 encoded video? Does that work?

[ErgoProxy1337]

No, sry. Those are photos taken from my iphone. Thats the default format. Btw. I dont think it is exactly the same problem as the thread creator has because I dont have on this video any full screen button like on the normal ones. So I have an different problem related maybe to the H265 codec.

For normal videos like mp4, it works on normal mode and also on full screen.

[kuzmos]

My videos are taken by Samsung s10+ in h265 codec, either fullHD or 4K.

Alright! I added an experimental setting in the latest version. It's called "Always transcode videos". This will activate transcoding.

This is not yet ready for production use, but it would be useful for me, if you could test video playback with this setting. Please remember to deactivated again after testing :)

Updated, enabled the feature, let's see what the night re-scan gives us in the morning...

My bad, realized don't need to wait for the re-scan. When I click on a video now, it starts playing - as expected, however the sound quality is superbad, and the video quality is not stellar. Also, which is worse, I can't access the full-quality version, or I don't know how - when I click on info -> file path, or right-click -> full-screen, it is still the same transcoded-quality video. ffmpeg process appears on the server of course. But definitely a step in the right direction.

Having the same issue as well, browser doesn't matter (edge, brave, firefox..). How/where can I enable video transcoding?

Interestingly, I can play older videos, i.e. only "newer" videos are broken - maybe the mobile phone/cam had an update. In any case, here's the mediainfo for the newish, not-working .mp4

This can be closed now. Latest version allows to enable transcoding of videos.
