Some FLACs won't play [Resolved]

[spookybathtub]

I'm having a problem playing certain FLACs in both my web browser and in iSub.
My library used to consist of FLACs ripped with XLD, and I had no problems. Recently, I ripped a bunch of CDs to FLAC using Ripstation software, and sent the files to my subsonic server using SCP. Then I chowned and chmodded the incoming files to match the old, working albums. But none of these new tracks will play. The log file doesn't show anything unusual. I attached a log snippet corresponding to a single track that won't play. In the web interface, when I click play, the timecode slider stays at 00:00 for several seconds, up to a minute — it seems like the amount of time it takes to transcode to mp3. I inserted a blank line near the end of the log, so you can see where it jumps, and at that moment, the next song starts trying to play (but fails). What could be the problem? I can play these files fine in VLC. I attached one here if you want to inspect it. http://dl.dropbox.com/u/33335399/Fly.flac
In the iSub app, I get basically the same behavior.
I'm running Subsonic 4.6 on a mac.

[BKKKPewsey]

Yep I tested the file that you posted and I cannot play in the web player either
However it plays fine in jukebox mode
I checked the file out using all my test progs and I cannot detect any errors with the file or the tags.
I changed the tags, removed the embedded album art, swore at it, still will not play
So I decoded the file back to a wave (which play np in SS) and then re-encoded back to a flac using MM (with compression 6)
That also plays np - so now at a lost why the original doesn't
Perhaps a user who uses flac more than I will have a solution but it must be something to do with the ripping/encoding software you are using.

[spookybathtub]

This is weird. What OS are you running, Pewsey?
I looked at the ffmpeg command in Subsonic's transcoding settings. It says ffmpeg -i %s -ab %bk -v 7 -f mp3 -
So I opened up a terminal (on the subsonic machine) and ran ffmpeg -i /Volumes/NewData/CDrips/2\ Bit\ Pie/2\ Pie\ Island/01\ -\ Fly.flac -ab 128k -v 7 ~/fly.mp3
Output is below. It produced a working mp3 file, which I then added to Subsonic's music folder and it played just fine. I'm stumped.

On a side note, when did Subsonic stop using lame, and why? According to the transcoding settings page, it's using ffmpeg to go straight to mp3 from any input format.

[hakko]

ffmpeg uses lame internally, though.

[BKKKPewsey]

I am running Windoze (server 2003) on my SS box but the odd thing is its only the web player (jw player) which has an issue.
SS via jukebox plays the original np - most odd

[spookybathtub]

It's hard to tell if this is a problem with Subsonic or with Ripstation. It's certainly not a problem with ffmpeg, as I can transcode the files on the command-line with no problem. Subsonic is the only app that can't play them, and Ripstation is the only app that creates FLACs that won't play. What to do??

[BKKKPewsey]

The problem is with the embedded artwork info in the field GRAPHIC_FRONT_COVER+
Deleted that tag and it plays np

See http://forums.linn.co.uk/bb/archive/ind ... 672-8.html

The GRAPHIC_FRONT_COVER tag is an ancient relic that's no longer needed and should be removed from your files. Back in the stone age, some control points couldn't handle album art in the correct FLAC format, so someone invented this nonstandard tag whose value is a huge hex-encoded string version of the embedded binary album art. You'll probably find that these files contain the album art in both hex and binary formats.

You can either ignore these warnings or you can remove the GRAPHIC_FRONT_COVER tags from your files.

[GJ51]

It's an ffmpeg version bug.

It runs fine in ver 4.5

ffmpeg -i %s -v 0 -f wav -
lame -b %b --tt %t --ta %a --tl %l -S --resample 44.1 - -

Which is why I'm still using 4.5 for music especially for mobile access. 4.6 won't do flac or mp3 to ogg either.

[spookybathtub]

Wow, thank you so much! That was driving me mad! I can take care of it all now with

Code: Select all

find . -name *.flac -exec metaflac --remove-tag=graphic_front_cover+ '{}' \;

Gary, I'm not sure I understand what you're saying. If I run ffmpeg on the command-line, it decodes these files just fine. If it works in Subsonic 4.5, doesn't that mean it's a bug with v4.6?

[BKKKPewsey]

Its because 4.5 has an intermediate step eg flac to wave which strips out that tag.
So its not really a 4.6 bug - I also noticed that if I tried to play using external player via a SS stream winamp could not detect the title & artist tags - strip out the redundant tag and all is well.

Your probably right. I've tried so many combinations, I'm just happy when I get something that works for me. My recollection was that I could only get transcoding to ogg working if I used the ffmpeg that was distributed with ver 4.4; when I replaced the ffmpeg from 4.4 in version 4.5 all my transcodings worked again so I assumed that something had changed in ffmpeg. 4.6 did use a different method for measuring the track length, as I recall, that also caused problems with the Android app playback. So, it does get a tad confusing sorting it all out as to what is actually causing which problem on which version. Just trying to write this sentence so it may be coherent is giving me a confusion headache.

I think, and hope, that all this gets fixed in 4.7 and we can have one version of Subsonic that can handle video well, transcode flac and everything else, including transcoding to ogg for mobile users. I haven't submitted the suggestion to Sindre yet, but I'd like to hear what the rest of you think about setting up a seperate transcoding scheme just for mobile connections. I find it cumbersome to have to check different transcodings for my individual players for my mobile users. It seems to me I remember that previous versions initiated all new Android players with whatever you set up for the first Android player, but 4.6 doesn't do that anymore.

Again, I apologize if I got any of this wrong as I try too many things to keep it straight all the time. About the only thing I can't forget these days is that it'll only be another year and a half before I can apply for my Social Security. I hope Subsonic and the othe SS will both still be there. LOL

[skidelo]

I was having this issue as well, except my problem tag was different.

It was the METADATA_BLOCK_PICTURE tag in my case. Also, some problems I ran into:
1) Make sure you have flac installed. (sudo apt-get install flac)
2) Put the .flac in quotes ('.flac')

Note: The find function is automatically recursive.

So my fix was:

Code: Select all

find . -name '*.flac' -exec metaflac --remove-tag=METADATA_BLOCK_PICTURE '{}' \;

[raidflex]

Resurrecting an old thread here, I am just unclear on exactly where the fix given is performed or ran.

I have the exact same issue with flac files. After reading this post I was not clear on where I am running the command provided above to fix the metadata issue. Where do I run this command to allow the web player to function normally? Basically all my flac files have this issue, I do not want to have to edit the tags of 20,000 files. Thanks.

[spookybathtub]

If your issue is the same, then the only solution is to delete the offending tag on every single file. But it's very easy, and can be done in a single command, shown above. Just enter it on the command line from the root directory which contains all your FLAC files. It should only take a few minutes to process 20k songs.

I am running this on a Freenas 8.3.1 server, would the command still be the same?

EDIT: Thanks for the help, this solved the issue!
