![]() ![]() The easiest and most compatible audio codec is AAC Stereo (pretty standard in MP4 movies and digital streams). ![]() Generally it's just the audio that needs to be changed and that takes much less time than a full conversion. It's faster than converting and keeps the quality. I use XMedia Recode to remux my files to be more Roku friendly. Roku 3 definitely handles files better than Roku 2. This guide does a good job of explaining what codecs are typically supported. ![]() So the Roku has to choose a particular audio stream to pass along, it can't send both." It doesn't send the original file over HDMI, the Roku has to take the original and then send the video and audio in the way that the HDMI spec dictates. I'm not an expert on HDMI, but think of it as sending audio and video in its own format. You have to put your Roku into the 5.1 mode for it to send that track over HDMI. If it's connected to a receiver, it can also pass through AC3. Basically, the only thing that the Roku understands and can deal with on its own is stereo AAC. "Stereo AC3 is only supported if it's passed through to a receiver that can process it (receivers will typically display PLII for this). I wish they could fix this in a firmware update or something. So even if it's two channel AC3 it can't play it natively. Meaning you have to have a receiver that can handle it. Roku basically only supports it on passthrough. The result will be a mp4 file with the same video track as the MKV original and a stereo, 256kbps AAC audio track. cd c:\Moviesįfmpeg -i movie.mkv -c:v copy -strict experimental -c:a aac -ac 2 -ab 256K movie.mp4ĭepending on your PC, the size of the movie and your disk (HD or SSD) this will take around 30 seconds to a minute. For this example, I assume you have a MKV called 'movie.mkv' in C:\Movies. You can use ffmpeg to copy the video and re-encode the audio. Inside the zip file you'll find a folder called 'bin' and a file in there called 'ffmpeg.exe'. Probably Windows 64-bit static for most people these days. Go here and get a build appropriate for your computer. It's a command line tool, but it's really easy to solve the problem you're having and once you've done that you can easily just do what I do and run it in a batch file over a directory of all your MKVs and fix them all. If you need/want to stream music to your TV from a DLNA server either mount a USB key locally to Roku or find anything other than RMP.Īs a final test, a friend loaned me a media stick of a different manufacturer and it's media player app saw the playlist, played the files, and even played the files within folders which RMP also appears to have heaps of trouble doing.Ffmpeg. "Home" and "September" as those are the only two songs on the playlist that don't contain any spaces.Īfter doing some additional digging I found this was a bug reported back in 2009 so I must conclude RMP has zero support and you're best off not wasting your time. Formatting my entire music library to strip out spaces is unworkable so I am able to play exactly two songs. m3u playlist if the file name contains any spaces at all. It appears that RMP is unable to parse/read/find media files via a DLNA hosted. So what is wrong here? Is there a preferred tool for building an M3U file? Can Roku Media Player navigate the paths in my current m3u file or do they need to be formatted differently?Īfter testing this in numerous ways, creating the playlists from numerous devices with various orientations of links in the playlist I have to conclude that RMP is, at best, 10% functional when it comes to playing mp3 off a DLNA server. My actual path is something akin to: \\PI\Backups\DLNA\file.mp3 I thought that the path given was odd since I don't have a folder called "Mediaitems", but if I copy the line and paste to any browser on my network the media file plays properly. The IP addressing is complete and correct in the file. #EXTINF:173,Phil Collins - You Can't Hurry Love #EXTINF:289,Phil Collins - Another Day In Paradise The M3u file is configured with a number of items, but here are the first two: When I went to Roku Media Player it was able to see the playlist but upon selecting the play list it displayed the error: "No compatible media found in: EasyDayListening.m3u" I used VLC media player to put together a playlist and saved it in the shared folder as: EasyDayListening.m3u The shares are reachable and usable by other devices and Roku Media Vault is able to play songs/albums if I manually select them. My DLNA server is hosted off of an OpenMediaVault implementation on an RPi 4. ![]()
