ffmpeg iOS and SDL2
24 décembre 2015, par user3487978I created a app for iPhone, the core source is based on the latest ffplay.c, I just changed the rendering part to support iOS, general it can play video, but I found the quality is not as good as enough, see screenshot below, the first image is the what expected, the second is image that my app on iPhone produced, and the last the produced by my app on iPad.
on the iPhone’s image, you can found there is a dash line, and the colour is not correct, it seems that there is a shadow of the image.
I am new to ffmpeg, can anyone help me what is the problem -
colored TV-Noise with windows
8 janvier 2024, par LookAndSeeI have some question to the colored noise at image 2 of the following thread :




- 

- how can i get this in windows ? I like a random pattern consisting of red, green, blue, white and black points, like 255:0:0, 0:255:0, 0:0:255, 255:255:0, 0:0:0 and 255:255:255 - no pink, no orange, no cyan ... at the first step.




but random in all 3 places always delievers (with ceil, floor or round) whole black, or whole white or bw-noise :-(
does it mean, the random(1) per point is 3 times the same in one computing-cycle ?


Any suggestion ?


This is what i tried :


ffmpeg -y -f lavfi -i nullsrc=s=1280x720 -filter_complex "geq=r=(round(random(1)))*255:g=(round(random(1)))*255:b=(round(random(1)))*255;aevalsrc=-2+random(0)" -t 5 output.mkv
