blurred stripe effect

[hvuitsme]

I don't know what caused the stripes on my screen (about 20% of the screen) and I don't know if it's because of my configuration or not, but every video has the same problem. Currently, there is an error in the MJPEG_JPEGDEC project:

I think because 170 not divisible by 4. You may try 168 instead.

I think because 170 not divisible by 4. You may try 168 instead.

i tried with changing width to 172 and it is also multiple of 4, but the problem is still not fixed, similar to 168

-168x320:

Arduino_GFX gfx = new Arduino_ST7789(bus, 42 / RST /, 0 / rotation /, true / IPS */, 168, 320, 35, 0, 35, 0);

ffmpeg -y -i nino.mp4 -ac 2 -ar 44100 -af loudnorm -c:a mp3 -c:v mjpeg -q:v 7 -vf "fps=30,scale=-1:320:flags=lanczos,crop=168:in_h:(in_w-168)/2:0" nino_30fps_mjpeg.avi

-172x320:

Arduino_GFX gfx = new Arduino_ST7789(bus, 42 / RST /, 0 / rotation /, true / IPS */, 172, 320, 35, 0, 35, 0);

ffmpeg -y -i nino.mp4 -ac 2 -ar 44100 -af loudnorm -c:a mp3 -c:v mjpeg -q:v 7 -vf "fps=30,scale=-1:320:flags=lanczos,crop=172:in_h:(in_w-172)/2:0" nino_30fps_mjpeg.avi

No idea, can you also try 160？

-160x320:

Arduino_GFX gfx = new Arduino_ST7789(bus, 42 / RST /, 0 / rotation /, true / IPS */, 160, 320, 35, 0, 35, 0);

ffmpeg -y -i nino.mp4 -ac 2 -ar 44100 -af loudnorm -c:a mp3 -c:v mjpeg -q:v 7 -vf "fps=30,scale=-1:320:flags=lanczos,crop=160:in_h:(in_w-160)/2:0" nino_30fps_mjpeg.avi

actually mjpeg doesn't need the size to be a multiple of 4, cinepak does, but I tried with 160 as above, it shows that MJPEG_JPEGDEC is really having a problem

[hvuitsme]

Is this problem solved? @moononournation
