Not staying at 30fps

[mmccaff]

I noticed that the "keep ffmpeg stream at 30 fps" issue was marked as done in the readme, but I am seeing the same behavior where it starts at 30 and then drops down.

FWIW, I also noticed that if I include more images in the web site, it drops down much lower, to around 2 or 3 fps.

What was the fix for that? Is it in the master branch? Are you really able to hold steady at 30 fps?

We fixed this with the silent audio streaming. its not staying at 30 fps but it works for me.

do you have problems with the stream?

The stream works with the web page as it is, but it seems when the page includes images with more colors (like a photograph) the fps is much less (~2 fps) and when it is that low, the stream does not work.

So far I have tried lowering the quality of the png output from phantom, but that made no difference.

Curious if you see the same problem if including more "complex" images on the web page.

Can you share an example code in a branch?

It looks like FB banned using reactions as a voting mechanism:

So I've stopped trying to learn what the problem was, but for the record, I did find that it was definitely the images (photographs) that slowed down the fps. Tests showed:

• 1 image dropped down to and stayed around 6.3 fps, which was fast enough to stream (a ~2 minute test).

• 2 images dropped down to and stayed around 5.2 fps, which was fast enough to stream (a ~2 minute test).

• 3 images dropped down to and stayed around 4.5 fps, which was fast enough to stream (a ~2 minute test).

• 4 images dropped down to and stayed around 4.0 fps, which was fast enough to stream. (a ~2 minute test -- on another occasion this case was 2-3 fps and not fast enough to stream).

Finally, I tested one single image which included all four of the photographs and it was 3.7 fps and streamed. So, it seemed like the fps went down with the "complexity" of the display.
