Good. But then I totally don't understand why that 64:45 is not used and

Since you have not provided the full information necessary to explain,

Hello,
Instead, the better solution would then be to give the SAR to whatever
calculates the SAR to store at container level not as a double or int,
but as a "AVRational", which contains the "num" and "den" values (in
this case 64 and 45)?
This is exactly what FFmpeg does (since forever).

Hello,
here's the command line output. The "test.mkv" was a part of a TV
recording stored in huffyuv format in this case. The input SAR of 1:1
was not correct (test.mkv created with avidemux), therefore I set it
with the "setdar" filter.
You said that the SAR provided by the container is

I do not agree with. SAR should not change, so the video always shows a
circle as a correct circle. Only the DAR should change from cropping.

Hello,
I'm confused about how ffmpeg handles the SAR (sample aspect ratio) and
changes it. Maybe someone can explain why this happens:
I've a video from TV with original size 720x576 pixels (PAL), which
shall be shown as 16:9 aspect ratio.
The SAR of the input video is correctly shown as
14 matches
