    While attempting to watch videos on the Jellyfin iOS app with the subtitle burning feature, I encountered a problem where the video continuously loads without ever starting. Through the logs, it became evident that the application is endlessly trying to run FFMPEG for streaming, although it constantly results in a failure.

    On a closer look at the FFMPEG logs, it appears that the issue is related to usage of the av1_nvenc  encoder:

    Conversion failed!
    As far as my understanding, the graphics card I use, Nvidia 3050, only supports AV1 decoding, while only the 40 series graphics cards begin to support AV1 NVENC. This raises the question, why was AV1 chosen as the default encoder? Additionally, how can I manually switch from it to a supported encoder like hevc_nvenc or h264_nvenc?

    Configuration Details:
    Physical Machine: PVE 6.8.4-2
    Virtual Machine: Ubuntu 22.04 with direct pass-through for Nvidia 3050 graphics card
    Jellyfin Installation: Running in Docker with the latest Jellyfin:unstable image.

    In the Jellyfin startup logs, the mention of av1_nvenc as a supported codec has been a cause of confusion, considering my graphics card's capability. The detailed logs are as:
