Force hardware transcoding for test purposes

[TheDreadPirate]

If you have any HEVC content, just play it in the Firefox or Chrome (they don't support HEVC) and that should trigger a transcode. If all your content is H264 you can lower the quality in the quality selector on most clients until it is below the bit rate of the video. That will also trigger a transcode. If you use Jellyfin Media Player, in the client settings I believe there is an option to always transcode to a limited selection of codecs.
