currently, ffmpeg does not accept expressions for the itsscale parameter
{{{
$ ffmpeg -itsscale '25/(24000/1001)' -i src.mkv dst.mkv
Expected number for itsscale but found: 25/(24000/1001)
}}}
workaround: pass a float number to itsscale
{{{
$ echo 'scale=20; 25/(24000/1001)' | bc
1.04270833333333333333
$ ffmpeg -itsscale $(echo 'scale=20; 25/(24000/1001)' | bc) -i src.mkv
dst.mkv
}}}
passing expressions already works for other parameters
{{{
$ ffmpeg -i src.mkv -af 'atempo=25/(24000/1001)' dst.mkv
}}}
would be nice to make this more consistent
so we can avoid extra calculations and rounding errors
