Yes, all supported non-mp3 audio formats are automatically transcoded to pcm using ffmpeg and sent to the mvpmcx2 player. I'd be happy to check your logs.
It does exist, it's local & I do recordings with NextPVR just not very often, there are lots of recordings directories & live-tv files in that directory, the only thing is my .ogg music is on a share that is mounted with sharehelper apart from that??
I copied the test .ogg file to a local drive & also changed my configuration to make the recording directory on the C:\ with the same no go result & the same error in the logs just pointing to the different recording directory.
transcode.txt was in the logs I attached & they have all been empty logs so it seems like the transcode for me never starts?
