Transcoding from FLAC to OGG for your Android FAIL

[alphawave7]

"As someone who is unfamiliar with OGG, can I ask why you would use it on the Android as opposed to just transcoding to mp3? "

I would like to know the answer; alas, it elicited a defensive response. Is it just a bandwidth/bitbucket saver?

[tschan]

I take the liberty of quoting myself:

I've determined through double blind testing that I can reach near transparency with OGG at 64 kbit/s. With MP3 I would need at least double that. And because my data plan is capped at 300 mb I want to save as much bandwidth as I can.

[alphawave7]

Ah..I missed the part where you 'said' you ABX'd with 128kbps MP3. My collection is all -alt.preset standard/extreme as I ABX'd only vbr MP3 from EAC/LAME encodes, and decided I couldn't tell the difference btw. a 256vbr vs. 225, but could from 225 vs. 192. Standard gets you a hair above 192 average. which was good enough for all that old classic rock/punk/metal anyway. :p My Jazz/Singer-songwriter/New Age/DownTempo gets more bits (extreme).

edit: Oh! only 300MB!

Thanks tschan, your answer sheds light on the subject and I appreciate it when users share their information. It's how we all learn more and benefit from an open exchange of information in the forum. I'll try to rip a cd or two to ogg to learn a bit more about it.

Sindre made a post that he change the player to read the file extension, which means that if the file is in a format that JW can read, it will play without transcoding. I'm not sure if it will fix your particular issue, but it's worth a try. Just go to the player menu in settings, pull up your Android player and uncheck the box for the oog transcoding. I just tried the same concept with an mp4 movie file and was happy to see that it works for the mp4 format.

Please let us know if it fixes your problem.

[tschan]

Well, most of my music is in a lossless format for archiving. I also rip cds only once to flac for storage purposes. I'm actually pretty anal about the quality of my music, but for listening in a noisy environment via headphones a Vorbis encode (with this particular encoder that has been optimized for low bitrate encodes) at 64 kbit/s is more than enough.

@GJ51: I understand that the JW player is the flash player of the web interface and has nothing to do with playback in the Android app. So the mentioned change should not affect me at all, or am I wrong?

[papatel]

Good to know that people are learning the advantages of ogg over mp3, but this is not why I started the thread. Sorry if I insulted anyone, but can we get back on track and try to debug? Please feel free to create another thread "Why you should stream ogg instead of X on your mobile device". This would help because more people will have this issue and try to contribute to a fix

I don't mean to complain, even with ogg streams breaking when you lose connection, this is still the best music streaming option for my android hands down.

I've got my nexus one and subsonic server waiting for instructions so I can post some sort of trace of the error.

[alphawave7]

Go to the market, and download 'SendLog'...it takes various snapshots of the Nexus's state, and you can email them to Sindre...he can likely tell you which formats are most useful for him.

[alphawave7]

Here's the low-down on SendLog:

[papatel]

thanks for the sendlog advice. Just used it to get a trace of the ogg playback failure (after an interrupted stream, intentional wifi turnoff while streaming...).

Vorbis player is complaining:
01-09 23:56:28.976 E/VorbisPlayer( 58): ov_time_seek() returned -131
My hunch is that the ogg stream is not being put back together properly when the data connection is re-acquired. I have the whole system log of me turning off wifi and back on again; I can provide if anyone thinks its helpful.

Thanks in advance to anyone who can help!

Looks like no one who has any insight has looked at my debug spew. I discovered if I transcode to ogg on my linux box first, then the stream on the Android client is able to recover even if the data connection is intermittent. I wrote a perl script to mirror my flac library in ogg format. Works if you have hard drive space to waste but I'm not really addressing the problem at hand.

I wonder if the fact that pre-transcoded ogg files do not corrupted shed's any light on this issue? Any ideas anyone? Thanks!

[papatel]

Does no one else transcode to ogg for Android client streaming? Please, if you are not experiencing this issue that is really useful information.

[GJ51]

Ok - I finally gave in and transcoded an album to OGG just for testing to see if I could duplicate your problem. So far I've tried it transcodding OGG>MP3 and playing the OGG files w/o transcoding and don't see any sign of the problems you describe. I'm on a Wondows Server 2008 R2 platform with the std Windows install and I'm streaming to my EVO 4G over 3G connection. I've killed and restarted 3g several times during playback. Each time, SS just picks up where I left off and keeps on truckin.

Try it out for yourself:

Select folder at bottom, "OGG Music"

I've deselected OGG>mp3 in the settings so they will play directly. If you need to test transcoding ogg>mp3 just let me know.

EDIT: OK, now I'm testing flac > ogg and I'm starting to see problems. I sent up a signal flare to Stozher, If anyone knows the answer, it's him.

I'm getting similar results. Over 3g, if the data stream is interrupted, the track will not play even after it is fully downloaded. I'm only getting it to work on wifi, and even then I'm getting quite a bit of stuttering. maybe it's just more than ffmpeg can handle, trying to squeeze a 1500 kbps flac into a 64 kbps ogg.

Many thanks! Seems to have fixed it. Wow - even cured a track that was previously botsed.

You da man Stozher.

I've put a flac album on my server for testing. Everything seems to be working fine.

Go to the Albums folder. Select Handel/Messiah. It will show as flac>ogg for all tracks. Plays fine on my EVO over 3g. No stutter, no skip, and it even sounds good.

[papatel]

Thanks guys, you both really rock. I actually found Stozher's post awhile back and tried those exact same transcoding settings without any luck. I tried again just now and on my Debian Squeeze system I still have the same issue. Subsonic: 4.3 (build 2078) – January 7, 2011
Really frustrating!

I confirmed that your server works GJ51 I can interrupt the stream 20 times before completion and the ogg file plays perfectly. Why can't mine with the same transcodings!?!?

here is a dump of my ffmpeg: I just got it using aptitude install "ffmpeg". Looks like it comes with --enable-libvorbis already. Do I still need a custom compile of ffmpeg or a different version? My version seems to Match Stozher's:

Thanks again for the help guys, anything else besides this you can think of causing my flac->ogg streams to get garbled when data connection is lost?

I guess I could confirm the issue by setting up a windows box with subsonic and go from there. But I don't want to keep my win7 box on all the time...

Thanks,
Patrick.
