Can you, please, confirm which gst1.0 provider are you using?

I'm sorry. I did not understood the question.

I guess you want to play a raw h264 movie (no container) and want to
define the FPS previously.
Because a raw h264 does not have timing, so you can change it anyway
you want/need.

But, you have one working cmd-line and one not-working cmd-line.

If you have one working cmd-line, what's the problem? (here is where I
got confused and need your help)
