Transcoding Expert Wanted
Posted: Sun Sep 16, 2012 11:49 amAfter installing R4.7, transcoding .wma lossless didn't work at all. I replaced the FFMPEG & LAME decoders with the most recent ones. That worked. It appeared that the FFMPEG replacement was essential.
One of the effects of an older LAME&FFMPEG was a terrible hiss when changing tracks. That happened with the last 4.7 beta.
Looking at the log file, as mentioned before, there's a long list of 'invalid dropings'. Though the sound quality is OK, something seems to be wrong here.
I used the recommended transcoding string: ffmpeg -i %s -ab 192k -v 0 -f mp3 -
And now using the recommended string from http://sourceforge.net/apps/mediawiki/subsonic/index.php?title=Transcoders#Transcoding_to_MP3: ffmpeg -i %s -acodec libmp3lame -ab 192k -f mp3 -
In both cases the 'invalid dropings' appear in the log.
Does anybody have an explanation?
This is the log, stripped from all the 'invalid dropings'
Thanks for answering!
