Replaygain scan (FLAC/m4a?): Failed

[GoogleCodeExporter]

Which version of Cantata?
1.5.1

Which build? KDE, Qt4, Qt5, Windows, Ubuntu, Mac?
Qt5 on Arch Linux

What steps will reproduce the problem?
1. Open the Replaygain Window for some FLAC files
2. Click the Scan button
3. In all 4 columns "Failed" appears, no further information

What is the expected output? What do you see instead?
The Flac files should be scanned, instead "Failed" appears.

Please provide any additional information below.

I don't know if any packages are missing, but flac, metaflac is installed on 
both server and client machine. 
MPD and cantata are not run on the same machine, but the server filesystem is 
mounted on the client machine and the correct path to the music files is 
specified within cantata. Grabbing the album art works from the file system 
works, and scanning .ogg and .mp3 files works fine.

Cantata itself calculates the replaygain - buy using some core from libebur128. 
First of all it decodes the files via libavcodec (from ffmpeg/libav). The way 
it works is that Cantata will use libav to convert the FLAC/OGG/MP3 into raw 
PCM audio - and feed this into libebur128. If it is failing, then it is 
probably this decoding of audio that is failing - but this is handled by the 
other libraries...

I've just tried converting 3 MP3s to FLAC (via avconv), and then performing the 
replaygain calc - and it is working for me (except the Peaks are all 1.0?)

Seeing as 'Failed' is appearing - perhaps your libavcodec (or is it 
libavformat?) is not linked against the required FLAC libraries? A long shot I 
know, but I'm not sure what else this could be.

p.s. Sorry for the late reply - I've been away from my PC for a while...

Hi and sorry for the late reply.

How can I find out whether the libav libs are linked against the FLAC libs? 

By the way, same problem with m4a files from itunes.

By the way, I enabled logging everything to terminal (CANTATA_DEBUG=-489335), 
and there is lots of output, but hitting the Scan button (which results in 
"Failed") does not output anything.

Then this definitely looks like an issue on your system. m4a scanning 
definitely works on my system.

What does ldd /usr/lib/x86_64-linux-gnu/libavcodec.so return? (the path to 
libavcodec.so might not be correct for your system)

Having previously said m4a is working - I have just tried on a new Ubuntu 14.10 
build, and it is not working for me either. mp3 is probably working because 
libmp3 is being used for those...

The m4a issue is fixed in trunk (for 1.6.0) and branches/1.5 (for 1.5.2) for me 
at least. Any chance you could checkout one of these and confirm?

I checked out and compiled trunk. I can scan FLAC files now (great news :)), 
but I still cannot scan .ogg and .m4a files.

Can you try again, I've made some more changes.

Great! ogg vorbis is working now. Scanning m4a still fails like it did before. 

Original comment by herrvong...@gmail.com on 26 Feb 2015 at 8:53

[GoogleCodeExporter]

Any particular m4a? Or all of them? m4a is working for me. If you have a 
copyright-free m4a that has this issue, please upload somewhere and provide a 
link.

All of my m4a files don't work, although I only have very few such files. 
They're all from itunes.

Original comment by herrvong...@gmail.com on 28 Feb 2015 at 1:23

[GoogleCodeExporter]

Please re-compile with the attached file (place into replaygain folder).

The run cantata-replaygain from the commandline. This should be located within 
the replaygain folder of your build folder. Run as (e.g):

build-folder> ./replaygain/cantata-replaygain <path to one m4a file>

then attach the output here.

My m4a's are from iTunes as well, so this is most odd.

After ~20 minutes, cantata-replaygain is still running on a ~5MB m4a input file 
and produced about 3GB of output so far. Whole ouput looks like:

..
dec a  136599313 0 29
..

I keep it running and report back when it's finished processing the file.

Hmmm... Should not take that long! I'd abort the run, that is not right - its 
just stuck in a loop!

Cantata's code is based upon the following:

https://github.com/jiixyj/loudness-scanner

Can you checkout that project, compile, and run the loudness-scanner app. If 
so, does it work for you?

In /usr/include/libavformat/version.h what are the values of:

#define LIBAVFORMAT_VERSION_MAJOR 56
#define LIBAVFORMAT_VERSION_MINOR  1
#define LIBAVFORMAT_VERSION_MICRO  0

Can you post a link to /mnt/stuff/rgain-test.m4a - or is this a copyrighted 
music file? If so, don't bother - don't want you getting in trouble just for 
this!

Also, does Arch use ffmpeg or libav? libav was forked from ffmpeg - Ubuntu uses 
libav.

I don't really know what the answer to your ffmpeg/libav question is. From the 
arch wiki:

FFmpeg is a complete, cross-platform solution to record, convert and stream 
audio and video. It includes libavcodec - the leading audio/video codec library.

Edit: Arch uses ffmpeg by default.

Please try this version - I've updated it to match the loundness-scanner code.

That did the trick, works fine for mp3, flac, ogg vorbis and mp4 (.m4a) now :)

Thank you!

Fwew!!!! Glad its finally fixed. Thanks for confirming. I've committed the code 
now - and will release 1.5.2 soon...
