Description Rune 2016-01-14 18:19:36 UTC

I had the Norsk Bokmål, nb_no, locale for regional settings. When entering negative amount for rotation video did not rotate when I entered, e.g. -900.

When changing regional settings for numbers to C, standard, the video rotated anti-clockwise 90 degrees when entering -900; as expected

Reproducible: Always

Hi,

Thanks for your report. I cannot reproduce, can you tell us which Kdenlive version you are using and which video effect you are using to rotate (a screenshot of the effect parameters might help)

Comment 2 Wegwerf 2016-08-02 10:43:45 UTC

Rune, can you please test if this bug is still present or has been fixed as part of other locale-related bug fixes in the recent stable 16.04 or recent beta 16.07.xx? How are you doing the rotation, using an effect or a transition? Which one?

If the bug has been fixed I would like to ask you to be so kind as to close this bug as resolved. Thank you very much for your cooperation!

Comment 3 Rune 2016-08-24 07:03:10 UTC

I've now tested with version 16.08.00 and Kubuntu 16.04: Still doesn't work. I use "Rotate [Keyframeable]" and enter -900 for rotate X: It does not rotate. I enter 900 and it rotates as expected.

My locale is set to nb_NO.UTF8

Comment 4 Wegwerf 2016-09-01 19:00:55 UTC

Can you please run the "locale" command in a terminal and report back its output?

Comment 5 Wegwerf 2016-09-01 19:03:28 UTC

Jean-Baptiste, I can reproduce this now, by temporarily switching the locale in a terminal session as follows:
$export LANGUAGE=nb_NO.UTF-8
$export LANG=nb_NO.UTF-8
$export LC_NUMERIC=nb_NO.UTF-8

Comment 6 Marcus Sundman 2017-06-24 06:35:34 UTC

I have the same bug with sv_FI.UTF-8 and the new kdenlive. This was driving me absolutely nuts!

Comment 7 emohr 2018-10-12 18:22:52 UTC

Please try with the actual Kdenlive version 18.08.2

Comment 8 Marcus Sundman 2018-10-14 10:12:08 UTC

Yes, this problem still exists in 18.08.2. Adding the "Rotate (keyframable)" effect and entering a positive rotation works, but a negative rotation does not work.

Rotate (keyframable)_negative

Tested on Kdenlive Windows 18.08.2 -> it works even with negative value (rotate forewards and backwards).
If not done, download the AppImage of 18.08.02
Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

Negative rotate does NOT work

Negative rotation does not work (unless I set LC_NUMERIC to C). This issue most likely won't affect windows, since I think it doesn't have any LC_NUMERIC environment variable at all.
