    render: Stop forcing format in restriction caps
    
    This was a workaround for decoders that were allowing upstream
    renegotiation while not actually supporting it, or while downstream
    was fixed and encoder upstream renegotiation often leads to new
    output format, thus the renegotiation was leading to NNEs
    
    This is possible thanks to the following commit in -base.

            encodebin: Also lock input caps when dynamic output is disabled
    
            With the way caps negotiation work in encoders, the only way to ensure
            that no downstream renegotiation is done in the encoder is to also lock
            upstream caps. Anyway with the current behavior upstream of encoders
            *require* to handle any file format so locking upstream format should
            be safe.

    Bump our GStreamer dependency to 1.14.1 as it is now required.
