Pitivi audio waveform is inaccurate and changes

[Stephen Irons]

Binary package hint: pitivi

Hooray, I can now import a long (60+ minutes) audio and video file into pitivi 0.13.4 because the timeout is gone (or something). However, when I import a 60 minute WAV file, the following problems occur with the waveform display of the audio track:

* Towards the end of the track, the waveform display is about 15 seconds ahead of the actual sound output. In other words, the display shows the applause at the end of the concert occuring while the musician is still playing.

* As you move the playhead position along the timeline using the arrow keys, the audio display changes underneath the playhead position.

These two defects make it difficult to align the audio with the video.

I need to do this because I record concerts with a high-quality audio recording device and a consumer video camera, leaving both of the running for the full duration of the performance (or at least until interval). I have a second video camera taking close ups of the performers, audience, etc. Afterwards I combine the high-quality audio with the video, and cut-in close-ups where appropriate.

I have just discovered the Pitivi bugzilla database, and found the waveform changes part has already been reported as
