Describe the bug
--camera-id=0 (back, 4000x3000, fps=[15, 29, 30])
--camera-id=1 (front, 2328x1748, fps=[15, 30])

When i select --camera-fps=24 i am getting ~23fps video when i select --camera-fps=15 fps i am getting 

1.2fps
full command scrcpy -b1M --record-format=mp4 --no-audio-playback --video-source=camera --camera-id=0 --video-codec=h264 --camera-fps=15 --camera-size=320x240

How do you know what frame rate you actually get?

What is the console output if you add --print-fps?

How do you know what frame rate you actually get?

Its recording the file i check fps then in mp4

What is the console output if you add --print-fps?

I am getting this error if i set --camera-fps to value less than 20

Did you try with another encoder? https://github.com/Genymobile/scrcpy/blob/master/doc/video.md#encoder

Is screen mirroring working correctly?

Is screen mirroring working correctly?

Regular feed (not camera) is working okay

Did you try with another encoder? https://github.com/Genymobile/scrcpy/blob/master/doc/video.md#encoder

Two of h.264 codecs are working with 15fps

15fps broken  --video-codec=h264 --video-encoder='OMX.qcom.video.encoder.avc'
15fps working --video-codec=h264 --video-encoder='c2.android.avc.encoder'
15fps working --video-codec=h264 --video-encoder='OMX.google.h264.encoder'

None of h.265 codecs are working with 15fps, wonder why?

15fps broken  --video-codec=h265 --video-encoder='OMX.qcom.video.encoder.hevc'
15fps broken  --video-codec=h265 --video-encoder='OMX.qcom.video.encoder.hevc.cq'
15fps broken  --video-codec=h265 --video-encoder='c2.android.hevc.encoder'

My goal is to output 4000x3000 video feed at 15fps.

Problem is that two codecs that work with 15fps stop working at resolution higher than 2304x1728 giving this error:

Any of this commands will produce above error
scrcpy -b50M --no-audio-playback --video-source=camera --camera-id=0 --camera-fps=15 --camera-size=4000x3000 --video-codec=h264 --video-encoder='c2.android.avc.encoder'
or
scrcpy -b50M --no-audio-playback --video-source=camera --camera-id=0 --camera-fps=15 --camera-size=4000x3000 --video-codec=h264 --video-encoder='OMX.google.h264.encoder'

while this one works fine
scrcpy -b50M --no-audio-playback --video-source=camera --camera-id=0 --camera-fps=15 --camera-size=640x480 --video-codec=h264 --video-encoder='c2.android.avc.encoder'
