`RolesExtractor.extract()` does not list the roles correctly

[IAmVigneswaran]

On our latest build of Marker Data, when drag and drop timeline into Roles Workflow Extension, it does not list the roles correctly.

I need the FCP project for this.

Here is the test project.

Thank you.

Related with #90

For Audio only timeline, the extract Video Role is shown. Maybe like #91, we can keep Video Role & Subrole empty where there no assign or not applicable

Also, I noticed that the Effect Roles is not shown correctly.

Found the culprit - there was a bug in the FCPXML parser when reading the role attribute from title elements and it was reading the wrong attribute.

Roles extraction should work correctly now.

I haven't tested an audio-only timeline yet.

re: Effects, I don't know what's going on there. I processed a large project that had the role and it was parsed out as Effects.Effects-1 in today's build of Marker Data.

Here is a sample timeline for your test.

I think Effects.Effects-1 is normal.

btw, FCP refused to import this file saying it failed the DTD check. I had to open it in a text editor and fix a modDate attribute value which contained some odd characters.

I noticed that FCP shows the Effects role as Effects-1 for this project, but the XML itself only contains "effects" as the audio role name. I think FCP is using shorthand for some built-in roles knowing that it auto-generates the implicit -1 role in this case, instead of actually writing effects.effects-1 to the XML. This definitely complicates things if we want to try and mirror what FCP is showing. But functionally it should still work since at least it can be used to filter roles.

<asset-clip ref="r2" offset="0s" name="Forest Day" duration="1550549/24000s" audioRole="effects">

Whereas some so-called default roles are written in full to the XML:

<audio-channel-source srcCh="1, 2" role="music.music-1"/>

For Audio only timeline, the extract Video Role is shown

Ok this is now fixed in DAWFileKit. It was erroneously injecting the Video role automatically for asset-clips but shouldn't now.

Fix will be in 0.3.5.

Seems like the issue still persist. For some reason, video role is not listed?

Here is the FCPXML.

My bad!

I realise that the "Video" role can only be shown when the clips on are assign a video Role. When video Role is not assigned, it is defaults to the Dialogue Role. Which is the correct behaviour.
