** Description changed:
[Impact]
- <fill me in with explanation of severity and frequency of bug on users and
justification for backporting the fix to the stable release>
+ The problem was that libav got updated in Precise and that the command line
options of avconv were changed. This causes quite some presets to not work at
all. ffmpeg/avconv will just report an error when these presets are used and
will fail to convert the file as requested. The fix has no winff source change
and is low impact as the presets are in a text file and only the none working
presets are changed.
[Text Case]
- <fill me in with detailed *instructions* on how to reproduce the bug. This
will be used by people later on to verify the updated package fixes the
problem.>
- 1.
- 2.
- 3.
- Broken Behavior:
- Fixed Behavior:
+ Warning: if you are testing this with the broken and the fixed Winff, be sure
to remove ~/.winff/presets.xml in between the tests.
+
+ 1. Start Winff
+ 2. Press Add and select a video for conversion
+ 3. Select "VCD" in "convert to" and "PAL VCD (HQ)" in preset
+ 4. Provide an output path (e.g. /tmp)
+ 5. Press convert and wait
+ Broken Behavior:
+ - ffmpge/avconv will report an error
+ Fixed Behavior:
+ - ffmpge/avconv will convert the file
[Regression Potential]
- <fill me in with a discussion of how regressions would typically manifest as
a result of this change. It's assumed that all candidate patches are
well-tested and have low overall risk of regression; but if there's an area of
concern be sure to call it out so testers can check it.>
+ In principle, I can hardly think of a potential regression. The possible
regression is that one of the changed presets did not need a change (I tested
this but maybe I made a mistake) or, not really regression but just no
improvement, the new presets are wrong in other ways than they were before.
Both issues were tested by me to the best of my abilities, but very maybe the
latter depends on the specific video file that I used. As no code is changed, I
can not believe winff to be impacted.
