Extension name

Extra Metadata Loader

Issue Description

4K trailer videos downloaded by Extra Metadata Loader often fail to play in Playnite.
Most of the failing trailers are encoded in AV1 or VP9 codec.
When I manually convert the same video to H.264 / AVC (MP4), it plays correctly.

This seems to be a playback compatibility limitation rather than a crash, but it affects usability because many trailers downloaded in 4K do not launch or show a black screen.

Installing external codec packs (like K-Lite) or manually converting using handbrake helps, but these are workarounds, not real fixes.

Steps to Reproduce

Download trailer using Extra Metadata Loader

Trailer downloads in 4K (usually AV1 or VP9)

Try to play trailer in Playnite

Video does not launch or shows black screen

Expected Behavior

Trailer should play normally regardless of codec, or there should be an option to limit codec/resolution (for example force H.264.

Additional Notes

Current workarounds that work:

Manually converting trailers to H.264 / AVC or using k-lite media foundation

Installing K-Lite Codec Pack

But it would be helpful if there was an option to:

support any video formats normally

How are you downloading the videos and from which source? Videos of that quality are not found on Steam as far as I know and I don't recall that quality being downloaded from YouTube either.

The reason they are not playing is because the video player used by the extension internally uses Windows Media Player, which is not compatible with those codecs so they need to be converted to a compatible format. If you are downloading the videos within Playnite using the extension, in theory it should already be being done after downloading a video but it's a bug if it's not happening.
