dopwav large files

[MINORISUKE]

As I tried to play a file DSD256 2.8GB (17 min.), the playback was normal without dopwav transcoding.
However, only the first 20 seconds could be played with dopwav.
The BubbleUPnP showed the correct duration 17 min. As soon as the playback started, it was reduced to 20 seconds. After 20 seconds, the next track started to play.

I thought a transcoding process took place while streaming, which means it does not matter how large the file size is.
How can I play this 2.8GB DSD256 file in DoP? It is the 3rd movement of Mahler Symphony No.5.
