Will Roku ever actually play mp4 files properly?
When I have any video file I want to stream to Roku I have to convert them to mp4 then it is hit or miss whether roku will play them or not. Some will start right up and play nicely and others especially larger HD files will not work at all. When I convert I always use h264 for video and aac for audio because these are the codecs that are supposed to work. It’s the same whether I stream the file or put it on a USB drive and plug it in so it’s not the streaming software’s problem. I wish Roku would get their stuff together and write some software that actually works with video files, as it is it truly sucks.
Why Roku not play some MP4 files?
You can use the Roku media player channel to play own personal video right on your TV via home’s PC, DLNA server or Roku’s USB port. However, only supported file types will be shown in Roku Media Player channel. From Roku media player channel supported file types, we can see that Roku 3/2/1 can playback H.264/AVC MP4 files, while on Roku 4, you can also play 4K H.265/HEVC MP4 files. If the MP4 is encoded with other unsupported video codec, you will definitely fail to open them in Roku Media Player from USB drive.
For people who try to stream unsupported MP4 files to Roku via Plex, the Plex Media Server will automatically transcode the incomaptible files to Roku media player readable file formats. However, as the transcoding process is very CPU intensive, in addition, the transcoding process will also use the temporary disk storage for the converted media. If your Plex Media Server CPU is not faster enough or if your boot drive is very small, it is not ideal to perform the transcoding process with Plex Media Server.
When in that condition, it is highly recommended to convert MP4 to Roku media player supported file formats with a third-party video conversion tool.
