Bug 462258

I don't see any possibility to download the video without login on the Chinese site.
However, I assume that you have not yet selected a video decoder in the digiKam setup under the new video settings. Activate FFmpeg in the setup.

In digiKam 8.0, I active FFmpeg in the setup and restart the application, however it still cannot preview and play my avi video, can you give me a email address and I send the avi video to you, it is too large to add attachment here.

Hi,

AVI is a container where different kind of encoding can be used. Please, use ffmpeg or another tool to identify how the avi chanel are store in container. ffmpeg -i foo.avi must be enough.

The video is recognized with video codec "None" due to errors. Some time ago we disabled the playback of videos with unknown video codecs. The video would generate some FFmpeg errors at the beginning, but it would still play. I think I'll add an option to the video settings that will still try to play video with unknown video codec detection.
