I just realized that this wont work for me either, with the frames. The remote server did not write anything in the frames when running that commad. Unsure why but i just get [FRAME] [/FRAME] [FRAME] [/FRAME] when running that on the server.
so i still need to change the bitrate from the read 330k to the correct 320k. Is that possible for a stream?
