[FFmpeg-user] ffmpeg: slide show on Windows

[RAPPAZ Francois]

Hello there

I'm on Windows 10 with ffmpeg and I would like to make a video (a slide) with a bunch of jpeg files and an mp3 music file.
I tried first
cat *.JPG | ffmpeg -y -f image2pipe -framerate 1 -i SligoAir_WhiteBlanket.mp3 -vsync vfr -pix_fmt yuv420p -movflags +faststart output.mkv
with fails with
cat: write error: No space left on device

Then I tried with
ffmpeg -y -f image2 -framerate 8 -i "%02d.JPG" -i SligoAir_WhiteBlanket.mp3 -vsync vfr -pix_fmt yuv420p output.mkv
It fails also with
Could find no file with path 'ffmpeg_run.bat2d.JPG' and index in the range 0-4
ffmpeg_run.bat2d.JPG: No such file or directory
(ffmpeg_run.bat being my batch file to run ffmpeg).

I did have some success with using

ffmpeg -y -f concat -i liste.txt -i SligoAir_WhiteBlanket.mp3 -vsync vfr -movflags +faststart -pix_fmt yuv420p output.mkv

liste.txt being the list of my jpeg files.

Now I see that double-cliking on the output file sometime work and sometime not: the player "Films & TV" on my pc return almost immediately and sometime the video is played correctly.
The VLC player does not show any image and the Windows media player shows the image but without sound...

Can I change my command above to have a mkv file that is played correctly on all three type of players ? Can the cat command or the sequence pattern argument be used on windows ?

Thanks for any help

François
