Transcoding H264 to H264 - DTS Audio to AAC/AC3 (solved)
i've got two questions.
So i'm running my PlexConnect and PMS on a Raspberry Pi 3. Everthings works fine so far.
If i watch an episode of a series or a movie (720p / 1080p H264 - AC35.1 - MKV) PMS sends the video and the audio via "Direct Stream" to the Apple TV 3 (so far so good).
When i start a other movies with the same options (720p / 1080p H264 - AC35.1 - MKV) PMS transcodes the video from H264 to H264.
The problem here is that the Raspberry Pi has not enough computing power to transcode video so it stutters and it is not watchable at all. Transcoding Audio from AC3 to AAC is not a problem for the Raspberry.
So why transcode a video from H264 to H264 when its already in H264? Is there anyway to allow PMS only to transcode the audio if necessary? Or needs the Apple TV a specific H264 format in order to play it properly?
I know that DTS is not supported by the Apple TV, but is there a away to transcode DTS to AC3 or AAC to get the video running?
