Broken SD-TV (720x576i) scaling (cutting / pause)

[Quantomax]

Hi,
if I cut SD Videos, e.g. seek Start and Stop of the movie with (1, 3, 4 and 6), I'll get an unscaled SD Picture in the top / left corner with some picture artifacts filling the rest of screen. Occasionally I too loose OSD temporary or completely.

Seems too me, as this is the same effect, that makes the HD picture "jumpy" in cutting mode...

Nevertheless, thanks for the plugin!

Regards,
Stefan

Interesting, exactly the same happens for me with the current GIT for 720p programmes. Here, 576i and 1080i is OK, but maybe it's still related. For me this issue is not when cutting (I only watch live TV), but with live TV.

I played a bit around. As soon as I activate either Denoise or Sharpening (or both) for 720p in the menu (by setting a value >0), the scaling works. Without that, no postprocessing is done for 720p for me (since no interlace needed and I commented out the ColorBalance part).

So the error seems to be that scaling is not happening when (for whatever reason) no postprocessing is running for a video format.

I wanted to double check, and changed video.c line 2562 from
VaapiVideoProcessing = 1;
to
// VaapiVideoProcessing = 1;
... and then indeed the scaling is not working anymore for all channels.

Since I am not sure if the problem that I noticed is exactly the same, I cut a separate issue (#95). I still suspect that both issues are related or have the same origin.

Might have been fixed by 3f01e86. Can someone verify?

Unfortunately, the error is still present...
