Comment (by v0lt):
Ok. I did more tests with AVI output.
{{{
ffmpeg -f lavfi -i testsrc -t 30 -pix_fmt yuv420p -c:v wmv1
output_wmv1.avi
ffmpeg -f lavfi -i testsrc -t 30 -pix_fmt yuv420p -c:v wmv2
output_wmv2.avi
ffmpeg -f lavfi -i testsrc -t 30 -pix_fmt yuv420p -c:v mpeg4

}}}
And I got these results:
{{{

wmv2 - OK
mpeg4 - OK
msmpeg4v2 - OK, warning, clipping 2 dct coefficients to -127..127
msmpeg4 - OK, warning, clipping 2 dct coefficients to -127..127
libxvid - OK
libvpx - OK
libvpx-vp9 - OK
libaom-av1 - FAIL, Unable to choose an output format for 'output_libaom-
av1'; use a standard extension for the filename or specify the format
manually.
librav1e - OK
libsvtav1 - OK
libx264 - OK

libx265 (vtag HEVC) - OK
libvvenc - broken output file (BI_RGB)
libvvenc (vtag VVC1) - OK
}}}
I checked file playback in ffplay.exe.
I'll quote myself from the first post:
> Yes I understand that saving HEVC video to AVI file is a bad idea. But
FFmpeg does not write any warnings or errors for this case.
But as we can see, for some encoders (libaom-av1) FFmpeg blocks recording
to AVI.
