Hanging working with transcript on Ubuntu 10.04

created an issue

Hi, I have an mp3 transcript and have been starting to work with is but getting hangs when I pause or stop the playback. It seems to be OK though if I just use the slider to navigate (although this is quite unresponsive)

I am using Sun Java as the default.

Happy to help debug

Can't see anything specific in the log on this error, though workspace log as follows

    Hi!

    Thank you for reporting this issue and sorry for the delay. Java is notoriously bad at handling audio files, especially on Linux, so we are planning to optionally rely on mplayer (internally): we could then support almost any audio files without hangs, jerks or performance issues.

    Although users could still interact with the audio file from the transcript editor, they would be required to install mplayer (apt-get install mplayer) beforehand though. Would that be acceptable to you?

    In the meantime, here are some tips I found helpful: restart your computer and only open Qualyzer (this makes sure that the audio device is exclusively used by Java), run Qualyzer as a super user (I don't personally recommend this, but it helps), try openjdk (it seems faster for me than the sun jdk).

    Hi

    Yes, using Mplayer would be fine if it fixes these hangs. Thanks also for the tips which I'll try.

    One other thing - it would be useful for me if the timestamp could also be inserted at text in the transcript and hence exportable in the RTF.

    Otherwise, kudos for the good work on this software!
