This behaviour may depend on flags in the file; providing the log for the time of playing may give the information to help resolve this.

Paul Correct. In an mp4 I believe the Roku is always going to play an audio track that is marked as "default". Can you please check the flags in the file? Thanks.

Grimmer 3 Posted January 7 Author Share Posted January 7 (edited) Requested info... Please let me know if there is something else that will help. At all times it played the English track through the home theater speakers. embyserver-63840226119.txt ffprobetext.txt Edited January 7 by Grimmer Link to comment Share on other sites More sharing options...
roaku 797 Posted January 7 Share Posted January 7 (edited) I don't think Rokus can handle dts in mp4s because the container doesn't officially support it and misbehave because of it. I was experiencing this weird behavior and switched to mkv after having the issue explained to me here. I'll try to dig up the thread. Edit: Here's the thread from my encounter with the issue with Roku, DTS, and MP4: Edited January 7 by roaku Link to comment Share on other sites More sharing options...
Grimmer 3 Posted January 7 Author Share Posted January 7 I was looking into that as well... Got this from the Roku website: I changed the container to MKV and the audio selections are working from the Roku. However, the stats for nerds is not updating. I even turned the stats off and back on again but they were still out of sync. Despite the stats for nerds stating English, the audio was Spanish. It seems the problem has been uncovered and not difficult to fix with a little ffmpeg action... ffmpeg -i input.mp4 -map 0 -map -d -c:v copy -c:a copy output.mkv -map 0 instructs to do all streams (otherwise it will only copy the default audio track) -map -d instructs to skip the data stream that any .mp4 with chapter markers will have (otherwise it will error) -c:v copy instructs to copy the video without transcoding -c:a copy instructs to copy the audio without transcoding Link to comment Share on other sites More sharing options...

speechles 1923 Posted January 8 Share Posted January 8 @ebrIt is possible during Direct Play that the stats may be incorrect. On GH #1503 and #1513 explain it better. Link to comment Share on other sites More sharing options...
