Hello everyone, I am studying the encoding of MOT slideshow. The encoding has been completed. However, when decoding with Dream v2.1.1, the picture cannot be displayed and only the following screenshots can be displayed. Can any experienced teacher give me some advice?!!
It's possible that you may have the appropriate encoding codecs, but not the decoders for that particular content stream. Or, Dream just doesn't recognise it.
Does your copy work with the MOT samples from the Files area? If it does not, it may be a clue that MOT is not working at all.
You may want to try to run Dream from the command line to see what errors are being produced when it attempts to display it.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I also used Dream V2.1.1 to test the example of the file area. The MOT display box cannot display pictures. Is it a problem with my version? I've attached a screenshot below.
Could you please provide some command line scripts for the dream software? I will use it for testing, it would be even better if there are websites that learn command lines. What version of Dream software are you referring to?
I've waited for about 10 minutes after running it in the command line, but there is still no image displayed. Which version of Dream are you using? I suspect it might be an issue with my version. Additionally, could you help me test a file? I generated it myself, and it only contains one MOTSlideshow service. I've attached the file and screenshots below. Thank you for your assistance!!
I'm using v2.3, but it's a version compiled on a Mac from the CVS codebase, not a pre-compiled distro. Shouldn't really matter though since I don't think the distro had any problems with MOT.
In your file, it looks like there's nothing in it, but it's very hard to tell because there's no audio to let me know if it's looping or not. In a future one, you might want to include an audio channel. Attached is what I see.
Maybe if @olliehaffenden has any time, he can investigate what the problem might be.
Hello, the mode I use is B mode, 10kHZ bandwidth, and the corresponding multiplexing frame length in the protocol is 5826 bits. When I was encoding the MOTSlideshow service, the size of a generated data packet was 472 bits. I sequentially filled every 12 data packets into the multiplexing frame and added 160 0s. Is this method correct? If there is any problem, Hope you can give me some advice.

That sample file has two slides in it: One that shows "BCE" and another with a picture of a transmitter rack.
The MOT display is not immediate and may take a while to display anything. Are you waiting for the entire sample file to play through?
From the terminal, the proper command for Windows is:
<path to dream>/dream.exe -f <path to sample file>/<name of sample file>or, for the sample you chose:
<path to dream>/dream.exe -f <path to sample file>/RTLwithSlideshow_ModeB_10kHz.flacLast edit: Mark J. Fine 2024-02-28
