S3Drive - Encrypted media playout not working.

I've purchased S3Drive and I'm trying to get the encrypted media playout feature to work, but it does not work for me. I am able to download the file through S3Drive normally. I am using the Flatpak version of S3Drive in Nobara Linux, which is currently running KDE Plasma 6.5.2 on Wayland. Log file (with debug on):

2025-11-18 01:24:02.007,INFO,"instance","Encrypted media play-out. File: **REDACTED**.mp4",""

The relevant parts of my S3 config: [s3drive_auto_**REDACTED**] type = s3 no_check_bucket = true server_side_encryption = aws:kms provider = Other [s3drive_enc_shared-znemesis] type = crypt directory_name_encryption = true filename_encoding = base64 filename_encryption = standard suffix = none (edited)

Hi @ZNemesis, Thanks for your purchase! Are you using external S3 or S3Drive's built-in? Rclone details as such are irrelevant, since given S3/crypt was configured in-app, rclone doesn't play a role here, since play-out decryption is done by S3Drive. Rclone details play a role e.g. when you mount or sync... or when you use rclone endpoint. (edited)

S3Drive built in, since Rclone can't do >50mb files

That's right. What's the video format by the way?

It doesn't work across h264 and h265 codecs in mkv and mp4 containers, as well as flac and and wav audio files not working

Hi again, It seems there was some regression regarding V1 cipher media play-out. Fix will be included in a next release. Thanks!

Hi @ZNemesis, this shall be already addressed in 1.15.7 release or newer.
