Trying to import video but nothing happens

[Beep6581]

I'm using Meshroom-2021.1.0-linux-cuda10.tar.gz and trying to perform photogrammetry from video. The manual does not explain how to do this, so I'm trying to figure out the procedure from the scant info in issue #232.

I click File > New Pipeline > Photogrammetry.

Then I click File > Import Images and select a straight-out-of-camera (Samsung S9) MP4 in HEVC format, and an MP4 converted to H.264 using ffmpeg. In both cases nothing happens. No hint whether it worked or not. The console shows only this:

WARNING:root:importFilesDialog fileUrls: file:///home/morgan/Downloads/20220208_102828.mp4
WARNING:root:importFilesDialog fileUrls: file:///home/morgan/Downloads/h264.mp4

The "Images" panel has a picture icon and a camera icon at the bottom, both show 0:

ffprobe on the videos:

ffprobe h264.mp4 2>&1 | grep Stream
  Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 14143 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)
ffprobe 20220208_102828.mp4 2>&1 | grep Stream
  Stream #0:0(eng): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709), 1920x1080, 8001 kb/s, SAR 1:1 DAR 16:9, 30 fps, 30 tbr, 90k tbn, 90k tbc (default)

So I don't know, did it fail? If so, why? Maybe H.264 and H.265 are unsupported - who knows? That's why I opened issue #1619.

If importing failed, there should be verbose feedback - a popup or an entry in a log. If it succeeded, I should see something somewhere too. And the manual should describe the process of importing video.

https://github.com/alicevision/meshroom/issues/232#issuecomment-579230462 mentions that dragging-and-dropping should be supported in 2021.1.0, so I tried it.

When I drag-and-drop, a new "KeyframeSelection" node appears, and a popup informing me of the fact.

So dragging-and-dropping seems to have worked, or at least something happened, while when using File > Import Images nothing happens.

When I remember correctly, only drag and drop support was implemented.

At the moment, the node does not smoothly integrate in the graph. When we no longer need workarounds like manually reimporting the extracted images, video support will be better integrated in the gui than it is now. Having a video option in the import menu would set expectations that can not be meet at the moment.

[Beep6581]

I understand, but it's undocumented and unintuitive that drag-and-drop of videos should work while File > Import Images does not. It would help if either that was explicitly documented, or if File > Import Images supported videos the same way drag-and-drop does.
