[mythtv-users] Nuvexport - mythtranscode std::bad_alloc

[Björn Gustafsson]

Hi

I have trouble with nuvexport. What happens is that i try to export a 
myth recording to an avi xvid file.
During the run I can see the memory used by mythtranscode increase more 
and more during the run. Eventually it aborts with a :

terminate called after throwing an instance of 'std::bad_alloc'
   what():  std::bad_alloc
Aborted

The recording is a 45 min 4:3 show. It aborts about when it has done apx 
20% of the file.

This is what I do:

Where would you like to export the files to? [.]
Enable Myth cutlist? [Yes]
Enable noise reduction (slower, but better results)? [No]
Enable deinterlacing? [Yes]
Crop broadcast overscan border (0-5%) ? [1.5]
Audio bitrate? [128]
Variable bitrate video? [Yes]
Multi-pass (slower, but better quality)? [Yes] No
VBR quality/quantisation (1-31)? [6]
Video bitrate? [768]
Default resolution based on requested dimensions.
Width? [720]
Height? [576]

Mythtv is the latest trunc. ffmpeg is from marillat:

Do I need another version of ffmpeg? Or is this a bug in mythtranscode?
