Having Issues transcoding to ogg vorbis after update to 5.0

Unread post by goard »

I use dsub(4.3) to stream music to my phone
Ogg Vorbis is my preferred format, due to it's bitrate/quality ratio, and I've used it flawlessly since version 4.8. My library is mostly mp3 files.

Yesterday I updated to 5.0 and I had a great deal of issues with the songs refusing to stream, but those have mostly been resolved.

However now, instead of giving the maximum bitrate I set (192 kbps), the cached bitrates now vary wildy. If the bitrate of the file is already 192 kbps, the cached file is usually pretty close.
If it is much greater , say 256 kbps, it goes way down to 128 kbps.

320 kbps files, are the worst, as the resulting cached files are also 320 kbps, and subsequently chew up a great deal of cpu time in the transcoding process.

Here are my transocding commands

ogg audio :

Code: Select all

  ffmpeg -i %s -acodec libvorbis -ab %bk -f ogg -
downsample command:

Code: Select all

 ffmpeg -i %s -acodec libvorbis -ab %bk -ac 2 -f ogg


I also noticed that whenever I try to set a max bitrate directly from the web client, it isn't saved, perhaps that's related?
Anybody know how I might fix this?

ffmpeg -v 0 -i %s -f ogg -vn -acodec libvorbis -ar 44100 -aq 3 -ac 2 -map_meta_data 0:0 -

Adjust aq # to set compression setting.

Thanks,

I'm a bit behind on my updating. I'll check it out when I do the next round.

EDIT: I use the WAR on Windows and it doesn't include the transoding files. They used to be posted here in the forums for download, but I can't find them and the Zeranoe site build page is currently down. Anyone remember where to find the current Madsonic transcode pack?

Thanks

Thanks, but no thanks. The link you list raises the big red malware flag on my Malwarebytes site monitor.

I'm looking for the most recent library posted here in the forums.

dont worry is not malware,the folder is from my madsonic install, the site is just free file hosting. is a false-posite in your link monitor, just because somebody don like flag the sites. is the same in most web monitor tools (avast, wot. etc).

if you need it i can upload here, or just download the windows version and save the transcode folder.

Regards.

Greetings what would you suggest for streaming wavs and aiff - I want to keep as much resolution as possible. I tried the MP3 conversion and find that is killing the cymbals on a lot of the music I listen to. I understand MAdSonic is Mp3 optimized, but isn't there some workaround to have less lossy-audio ?

The issue is that unless you use an external player you have to output a codec that the device you're using can play. If you're looking for the best codec to use for Android mobile, I'd recommend ogg as it is well regarded for it's efficiency and quality. You can adjust -aq x to get the quality you want with better efficiency than what is available through mp3.

On the desktop using JW Player, you're limited to the codecs it can handle, but I've never been able to get anything but mp3 to playback even though their page says that it can play aac, mp3, and ogg formats.

I've wondered for a long time why I can't get ogg to work, but looking at the chart on the page at the link it may be because I bever tried the HTML5 setup.
