Drag and drop append appears to be broken.

[jimmyrave]

When dragging and dropping, the first file loads, the following two don't and the export is just the first file.

Just encountered this problem with 2.7.3 64bit main release and the latest 190630 Nightly, upgrading from 2.7.0
Uninstalled 2.7.3 and installed 2.7.1 and drag & drop is working again. On Window 7 64bit

Just encountered this problem with 2.7.3 64bit main release and the latest 190630 Nightly

Which one? vsWin64 (native builds compiled using Microsoft Visual Studio C++), win64 (MinGW builds cross-built on Linux) or both equally?

Uninstalled 2.7.3 and installed 2.7.1 and drag & drop is working again.

Does this apply to the latest Windows 32 bits nightly (190702 at the moment) too? https://avidemux.org/nightly/win32/

On Window 7 64bit

Any ideas what should I do to be able to reproduce this issue?

Experienced same issue on Windows 10 64 bit.

2.7.1 64 bit Avidemux drag and drop WORKS.

2.7.2 64 bit and 2.7.3 64 bit drag and drop append does not work. HOWEVER using File>Append will work and also multiple selected videos dragged and dropped seems to work.

As suggested by eumagga0x2a, I just tried nightly build 32 bit Avidemux 2.7.4 190804_a9f8b0a64b6-fflibs 3.3.9 and drag and drop append DOES work.

Possibly a difference between the 64 and 32 bit versions?

Confirmed by downloading latest 64 bit nightly version 2.7.4 190804_f5d6dc9342e-fflibs 4.1.4 Drag and drop append does NOT work.

so yes it seems to be the 64 bit version that is having this problem.... at least for me.

2.7.2 64 bit and 2.7.3 64 bit drag and drop append does not work. HOWEVER using File>Append will work and also multiple selected videos dragged and dropped seems to work.

Other users in this topic report it exactly other way round: drag'n'drop of a single video works, drag'n'drop of multiple videos fails. All that remains useless unless someone gets a clue what might be the trigger for the failures as drag'n'drop consistently works for me on Windows.

As suggested by eumagga0x2a, I just tried nightly build 32 bit Avidemux 2.7.4 190804_a9f8b0a64b6-fflibs 3.3.9 and drag and drop append DOES work.

Possibly a difference between the 64 and 32 bit versions?

A different Qt version.

The 32bit version is built off the legacy-compat branch, not from the git master in a very old snapshot of MXE with an old Qt version (5.7.x vs 5.12.0 if I am not mistaken). There are two different 64bit versions, one natively built with Microsoft Visual Studio C++ on Windows and the other one cross-built with MinGW on Linux. Both use currently the same Qt version (5.12.0 if I remember correctly).

@all who reported drag'n'drop not working: does it work for you when you drop NOT onto the video display of the previously loaded video but onto a different part of Avidemux GUI?

It looks like I was able to reproduce it on Windows 10 in HiDPI conditions and with Qt autoscaling enabled only. The frame holding the video display accepts drops, but then nothing happens. Dropping e.g. onto codec widget or menu bar works. Looking into it.

edit: No, HiDPI scaling is not a factor here. Drag and drop consistently works when file manager window (the drag source) has focus and Avidemux is in background. If the Avidemux window is in foreground, drops onto video display as target fail, drops onto any other part of the GUI work.

Should be fixed now.

Should be fixed now.

Outstanding work! Much thanks!
Confirmed good fix on drag and drop append single file 64 Bit nightly build avidemux_r190814_win64Qt5_56 from 14 Aug 2019.

Thanks Thanks Thanks!
