AudioBook m4p files - madsonic unable to determine duration

Unread postby shivan » 02 Jan 2016, 16:15

I recently started collecting audiobooks and most that you download are in a series of mp3's. In order to use in other situations, I need to convert them to standard audiobook files with an extension of m4b. I am using a program called chapter and verse to convert the mp3 to m4A and then it takes the m4a files and creates an m4b book file. I have been testing on one book Contact by Carl Sagan. I have created one large book at about 217mb and two books with half in one and half in the other of about 108mb each.

I have the files playing in madsonic, but they get a log error: WARN StreamController Unknown duration for contact chapter 1-10. Unable to estimate transcoded size.

Small or large files play, but of course on the now playing screen there is no end time, no progress bar, just plays. I don't know it this is a transcoding error or madsonic just can't handle it.

Here is the latest transcoding setting i am using:

m4b mp3 ffmpeg -i %s -aq 0 -ar 44100 -ac 2 -v 0 -f mp3 -

I tried it with this previously with same results:

ffmpeg -i %s -map 0:0 -b:a %bk -v 0 -f mp3 -
