[BUG] enable_sps_framerate parameter only works for hardware encoder

[mikkelam]

Please only report one bug per issue!

Describe the bug
Cannot include enable_sps_framerate. As this interface is kinda hidden in how it switches, it's not easy for a user to understand this difference.

To Reproduce

FPS = 30
enc = H264Encoder(enable_sps_framerate=True, framerate=FPS)

Expected behaviour
A clear and concise description of what you expected to happen.

Console Output, Screenshots

  encoder = H264Encoder(enable_sps_framerate=True, framerate=FPS)
              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: LibavH264Encoder.__init__() got an unexpected keyword argument 'enable_sps_framerate'

Hardware :
rpi4 -> rpi5 is what made me see the problem

I could try. How would you like me to handle it? I cannot see a similar configuration on the pyav side. Should we give a warning or silently accept the flag?

Well, I think there is a "framerate" parameter in the codec context that one could set, and I think that does get reflected in the SPS. Though there might be some confusion about whether libav is talking about frames or fields, I'm not quite sure. But it might even be the right thing to do!!
