Thanks, I tried it but I get an "tcp://192.168.1.40:5556: Cannot

Command line and complete, uncut console output missing.
My apologies, result:

I seems my images might be too big for this
option, i.e. 2592 x 1944 = 5MB per image.
It's actually 10MB but I cannot believe you are running a
system that has issues with 10MB frames. Memory usage is
170MB here for 10 seconds using the mpeg4 asp encoder.
It is exactly 5,038,848 byte (one byte per pixel) that I'm sending per
frame.
I'm also baffled by this, as FFmpeg is not complaining when I'm using
the "-f rawvideo" option. Simply swapping it with "-f image2pipe
-vcodec rawvideo" causes this issue. I have the same issue when I try:
$ cat test*.raw | ffmpeg -f image2pipe -vcodec rawvideo -pixel_format
gray -video_size 2592x1944 -framerate 10 -i - -vcodec libx264 -x264opts
sliced-threads -pix_fmt yuv420p -preset ultrafast -tune zerolatency
-vsync cfr -g 10 -f mp4 test_file.mp4
I tried to set a buffer size using the -bufsize option,
but it did not seem to work.
How is this related?
I assumed that the -bufsize option might help, since it was complaining
about memory. Changed it up and down but it had no effect.
