Arrow Keys don't work (sometimes)

[andrewk8]

ADM 2.7.1 x64 on Windows 10 x64.

New issue in 2.7.1 that wasn't in 2.7.0 or late 2.6.x

I navigate videos mostly with the arrow keys: up/down to navigate between I frames; left/right to fine tune between frames.  Occasionally I drag the seek bar with a mouse, but that's less common navigation.

In 2.7.1, sometimes the left/right arrow keys don't work.  But the up/down arrow keys continue to work.  To get the left/right arrow keys to work, you can click in a few key locations in the ADM window.  Not everywhere works, though.  I know clicking under the navigation buttons (always?) re-enables left/right key.  There are certain places in the ADM window you can click and it won't re-enable the left/right keys, yet up/down continue to work.

Have you tried the latest nightly (currently r180702)? Just to be sure you don't see the regression in 2.7.1 release fixed by [editor/nextPicture] Update lastReadPts when the next image has been found in the cache.

[Jan Gruuthuse]

If problem persists:
Are you using
- An country specific keyboard other then US qwerty?
- Other [User Interface] preferences found @ Avidemux Menu: Edit: Preferences? see attached screenshot

You could perhaps try finding avidemux config file(s) and delete these if found?
Use file browser and search for config2 and config3, if these are avidemux related, just delete.
- \avidemux\config2
- \avidemux\config3
In windows to be found normally in AppData folder

[eumagga0x2a]

If the problem persists with the latest nightly, please provide exact steps required to reproduce the issue. If the issue is related to a particular video, please provide a sample.

I would not suspect Avidemux configuration and keyboard settings to be at fault in any way, but the log file (admlog.txt) might be very helpful.

[andrewk8]

... for the 2.7.1 release... Keyboard is US English.  Windows 10 default USB keyboard driver.

The %AppData%\avidemux\admlog.txt file was last written ~a year ago by ADM 2.6.21.  I've used ADM 2.7 and 2.7.1 since to edit videos.

Just happened again.

• Drag file from Windows Explorer.  Drop on ADM
• Use up/down arrow keys to navigate
• Using mouse, click the "A" cut point

At this point, right / left arrow keys don't work.  Up / down arrow keys still work to navigate to I frames.

Exited ADM and deleted the config2 and config3 files.  Steps above did not happen with the 1st video I cut with ADM, but happened with the second (same session).

Update: still happens in the July 2 nightly.

Can confirm issues also exists in Linux as well (LinuxMint 19.0 with XFCE).
Build Avidemux 2.7.1 - 4782c8568da-fflibs 3.3.7) - last build on 2nd July from GIT.

When this happens, if you click anywhere in Toolbar area, arrow keys (left/right) start to work.
Doesn't happen all the time - probably around 1/3 of the time.
Clicking in toolbar area seems to fix 'focus' issue to recognise keys again.

Did you build Avidemux yourself or did you use the appImage? I can't reproduce it (or better, can't make happen unintentionally) so far on my Fedora 28 system.

The only location in the Avidemux GUI which can stop arrow keys from being interpreted as previous/next picture is the combo box to set audio shift. So sometimes this combo box receives (unintentionally?) focus. Moving the focus elsewhere should revive the left/right keys again.

[eumagga0x2a]

I tried hard to reproduce the focus issue with the given steps on Windows 7 to no avail. Something else must happen to move focus to the audio shift input field which in turn would make left/right arrow to stop being interpreted as previous/next picture. Once this issue strikes again, pressing the tab key should be enough to move the focus to another GUI element, thus restoring the previous/next picture keyboard shortcuts.

So far, WFM, can't reproduce. Will try on Win10 later.

[andrewk8]

pressing the tab key should ... restoring the previous/next picture keyboard shortcuts.

Tab key confirmed to restore left/right arrow keys.

[eumagga0x2a]

Can't reproduce focus inadvertently without user interaction moving to the audio shift combo box on win10 either --> WFM.

Build on LinuxMint 19 via ADM supplied standard bash shell script from github.
I have changed OS from LM 18.3 to LM 19, and did a recompile for latest GIT source at time. Never had issue on LM 18.3 but that was a few commits earlier in terms of source.
As you say, click anywhere, or press tab, makes focus okay again and arrow keys work.

I am wondering if this is a QT regression and not specific to ADM. I have dvbcut with right arrow key input issue.

I am going to revert to LM 18.3 on spare machine and compile same GIT release and see if any difference to see if can help narrow this down.

I've not come across arrow keys issue on 64-bit 16.04 LTS or 18.04 LTS

I was building and testing Avidemux on macOS, Linux and Windows (7 and 10, 64 bits) using various Qt relelases and never experienced the audio shift combo box getting focus on its own. Something else I never use might be responsible. "Focus follows mouse" maybe?

[Jan Gruuthuse]

Sometimes I loose the avidemux text menus with mouse hovers over, need to restart.
