Media does not play in Safari/iOS as these are reported not to play mp3 audio.
Audio should be encoded with AAC.

API fixes introduced with #6 and #4 also need to be applied in commands.
Query the youngest subtitle.

If the input wav is not found the task should be marked finished. As of now such is kept forever and fills the task queue.

This is an issue that exists after the Babelium downgrade was implemented on lernen.goethe.de.

There are Babelium assignments that use more than one recording role. In the Babelium backend it is configured which recording section belongs to which role.

When starting an attempt, first a role is chosen. Only in recording sections of this role recordings can be made. This means that if there are recording sections for other roles in the video, no recordings are allowed for them - they should not be displayed as recording sections and the video should be played normally for these.

This is not working. Regardless of which role is selected, the recording sections for all roles are displayed in an attempt and recordings can be made for any role.

Depending on the selected role, only recording sections of this role must be displayed.

Example: https://lernen.goethe.de/moodle/mod/assign/view.php?id=45967829

According to a dev, the api endpoint does not deliver correct roles.

conversion tasks need locking as they are not synchronized and would clash with each other

It seems that in text that is coming from the Babelium backend, umlauts are not taken over.
Example: https://lernen.goethe.de/moodle/mod/assign/view.php?id=45988409

The Role "GesprächspartnerIn" is displayed as "GesprchspartnerIn". The text "Bitte wählen Sie aus und sprechen Sie." is displayed as "Bitte whlen Sie aus und sprechen Sie."

This needs to be corrected. I checked the Babelium backend and there the text seems to be correct, so I assume there is an issue with taking the text from Babelium and displaying it on Moodle.

The Babelium Video "DO B1 4-3-13" has the following issue:

In the Babelium backend the second half is configured as recording section. In Moodle though, only the last tiny bit is displayed as recording section.

This needs to be corrected so that Moodle uses the same configuration for recording sections like the one that was set up in the Babelium backend.

According to the webservice response call, the recording window that Moodle gets has the following time:

[{"id":0,"showTime":110.97,"hideTime":111.47,"text":"Bitte sprechen Sie jetzt.","exerciseRoleName":"Felipa","subtitleId":"217","exerciseRoleId":1}]

This does not reflect how it is configured in the Babelium backend.

It is assumed that this is caused by the backend configuration where the recording widow might end with (or even after?) the video. However, I don't think it's the case. In the next example the issue is the same but the video does not end with a recording window in the end. Also, the issue is the start time, not the end time (see screenshots).

The same is happening with the Video "DO 5.3.8". There are 15 recording sections and the last one is cut off (see screenshot). In the Babelium backend the section is not cut off.

Note: I tried if editing subtitles and saving them in the backend whould change the display on Moodle, but it did not. It seems that always the first subtitle version is loaded when adding

submitted, probably empty response (only 44 bytes file) troubles ffmpeg. Process eats up 100% cpu on babelium server (invoked from babelium:convert:response task) and don't stop.
