Hi
In the last weeks, I've encountered a "non-playable" problem several times with m4b encoding (unfortunately not reproducable).
There's several effects, that I will list here - I would be glad, if someone gave them an eye... (btw.: latest, 13.1 version, all codecs up to date, fresh and clean install).
Players used: JRiver Mediacenter (JRMC), version 12 & 13, latest builds
ITunes
(2nd Generation, latest Firmware)
Material: several CD-Rips to 44.1/16 wav/flac, ac3-files from Audiobook-DVDs
Nero Encoder is from their website and installed as required.
- conversion ac3 -> m4b: does not play in JRMC & IPod, plays in ITunes (though the time shown is twice as long as the actual length!). When doing a conversion to highbitrate mp3 first, and then to m4b: produces playable files, but is much work...
- conversion Flac -> m4b: some files do not play on the Ipod, but still in JRMC and ITunes
- conversion wav -> m4b, later on Tag-Update in Explorer (right-click, Tag Update) Plays before the tag-update, does not play in any player after the tag-update in JRMC and IPod, sometimes even not in ITunes
- Ripping and directly converting Audiobook-CDs to m4b produces unpredictable results: some files play, some don't, even in ITunes.
Since I can see no pattern here, I am a bit confused on what could be the reason. One thing, though, seems to me a possible cause: updating the Tags in m4b (either during the rip or later on in file-conversion) seems to mess up things.
