Description Edward Hervey 2010-09-14 12:07:33 UTC
+++ This bug was initially created as a clone of Bug #629607 +++

To reproduce, in the rendering settings choose:
- Container: Matroska muxer [matroskamux]
- Audio: FFmpeg DVD subtitles encoder [ffenc_dvdsub]
- Video: FFmpeg MPEG-4 part 2 encoder [ffenc_mpeg4]

Try rendering, and you will get:

Traceback (most recent call last):
  • File "/usr/lib/pitivi/python/pitivi/ui/", line 147 in _recordButtonClickedCb
  • File "/usr/lib/pitivi/python/pitivi/ui/", line 210 in addRecordAction
    self.have_video, self.have_audio)
  • File "/usr/lib/pitivi/python/pitivi/", line 619 in export_settings_to_render_settings
  • File "/usr/lib/pitivi/python/pitivi/", line 420 in __init__
    self.output_stream.pad_name = p.name_template
AttributeError: 'NoneType' object has no attribute 'pad_name'

I don't know if this traceback can be fixed, or if it really is normal since it's... actually not an audio codec. But if it isn't, it shouldn't show up in that list in the first place.
