<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not sure about the hard dependency of Xine. We don't depend on any particular audio backend since we use Phonon---what is the feasibility of using Phonon's AudioDataOutput for extracting the audio data, do you know? Some Amarok devs have been looking in to using it for audio fingerprinting, but it wasn't completely bug-free last I checked.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hmm, i can not find any way to make it just "dump" decoded date, everything this class can supply - dumps currently played portions of a track. And i didn't find a way to control playback to make It faster in case of decoding.
Guess I have to find another way.</pre>

I don't mind the Xine dependency as long as (a) it's very clear it depends on Xine (b) There are CMakeLists checks for xine that enable it only if Xine is found, and disable it if Xine is not found. I don't know wh at the rest of the team thinks.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not keen on the xine dependency. First of all xine is hardly maintained (they have like one developer left or so), which poses problems with bit-rot and possibly security issues. Then, it _is_ an extra dependency, with a whole slew of implicit dependencies that xine pulls in. Next issue, is xine cross-platform? Last I checked it did not run on Windows, and that automatically rules it out.
So I realize that Phonon is unfortunately (not yet?) up to the task. We should talk to the Phonon devs about a possible extension here.
As an alternative, how about using FFmpeg? We already depend on it for Teo's Transcoding patch. It's cross-platform. It's well maintained, and widely available on all distros. Sounds like a good match to me!

Btw found out that in last (mb both posted) diffs, checks for libofa availability was missed from CMake script.</pre>

Thank you, now I don't need to invent a bicycle (thanks God, that I only finished with libmad support =) ).</pre>

There are three independent parts:
1. MusicBrainzFinder class - used to make requests to MusicBrainz server and process replies. All relies process in separate threads by MusicBrainzXmlParser class. For a search uses guessed from a file name track information. No external dependences required.
2. MusicDNSFinder class - used for the same purpose as MusicBrainzFinder, but i communicate with musicdns server and receives track's PUID as a reply. Replies ether process in separate threads by MusicDNSXmlParser class. Fingerprints generated by libofa (the only external dependence in entire patch). For track decompressing (MusicDNSAudioDecoder class) used xine engine (I'm not sure is It a good choice, but amarok based on phonon media-engine, that uses xine. So we don't deed to pull any other dependences). Received PUIDs sends to MusicBrainzFinder class, for a search routine.
3. View. All classes used for store (MusicBrainzTagsModel, MusicBrainzTrackListModel) and display (MusicBrainzTagsModelDelegate) purposes.</pre>
