Audio stream language tag of transcoded mp4

Post by yosukear »

Hi,

I am using TS-451(firmware 4.1.1).

I found the converted audio stream did not keep the original language tag
when I converted a mkv file into a mp4 by the QNAP transcode function.
The original mkv file has "Japanese" audio stream, but the converted mp4 file has "English" audio stream.
Both on-the-fly transcode and background transcode cause the same result.

My chromecast plays the video file with no sound if there are no "Japanese" audio stream.

Can I correct this behavior of transcode function?

Thanks
