Local decoding does not work. Why is that?

[Nemgathos]

After installing the latest version of YouBit, I wanted to encrypt a file. So, I took a look at the help page of YouBit’s encode method:

username@computername:~/Videos/YouBit_Test$ python3 -m youbit encode --help
Usage: python -m youbit encode [OPTIONS] INPUT [OUTPUT]

Arguments:
  INPUT     A path to the file you wish to encode.  [required]
  [OUTPUT]  The directory in which to save the output.  [default:
            /home/unsername/Videos/YouBit_Test]

Options:
  --ecc INTEGER                   Set the number of ECC symbols to use for FEC
                                  encoding. Set to 0 to disable ECC. Max 255.
                                  [default: 32]
  --res TEXT                      Set the video resolution. Can be 'hd', '2k',
                                  '4k' or '8k'.  [default: hd]
  --bpp INTEGER                   The 'bpp' or 'Bits Per Pixel' value to
                                  use.Determines how many bits to store in
                                  each pixel of the video. 1, 2 or 3.
                                  [default: 1]
  --crf INTEGER                   The 'crf' or 'Constant Rate Factor' to use
                                  during video encoding. 0 - 52 inclusive.
                                  [default: 18]
  --zero-frame / --no-zero-frame  Whether or not to use a zeroframes. See the
                                  README.md for more information.  [default:
                                  no-zero-frame]
  --help                          Show this message and exit.

I, then, locally encoded a file by writing …

python3 -m youbit encode ~/Videos/YouBit_Test/testFile.txt

…, uploaded it to YouTube, downloaded it once again and now tried to decode it.

First, I took a look at the help page of YouBit’s decode method:

username@computername:~/Videos/YouBit_Test$ python3 -m youbit decode --help
Usage: python -m youbit decode [OPTIONS] INPUT [OUTPUT] ECC BPP ZERO_FRAME

Arguments:
  INPUT       A path to the file you wish to decode.  [required]
  [OUTPUT]    A path to where you want to save the decoded file.  [default:
              /home/username/Videos/YouBit_Test]
  ECC         The number of ECC symbols that were used during encoding.
              [required]
  BPP         The 'bpp' or 'Bits Per Pixel' value that was used during
              encoding.  [required]
  ZERO_FRAME  Whether ot not a 'zeroframe' was used during encoding.
              [required]

Options:
  --help  Show this message and exit.

Following the rules listed on this help page, however, did not help and I got an error message:

username@computername:~/Videos/YouBit_Test$ python3 -m youbit decode ~/Videos/YouBit_Test/video.mp4 ~/Videos/YouBit_Test/ 32 1 false

    decoder.decode(output=output, ecc=ecc, bpp=bpp, zero_frame=zero_frame)
TypeError: Decoder.decode() got an unexpected keyword argument 'output'

What went wrong? If a do not write ~/Videos/YouBit_Test/ as an optional [OUTPUT] parameter, I get the following error message:

username@computername:~/Videos/YouBit_Test$ python3 -m youbit decode ~/Videos/YouBit_Test/video.mp4 32 1 false
Usage: python -m youbit decode [OPTIONS] INPUT [OUTPUT] ECC BPP ZERO_FRAME
Try 'python -m youbit decode --help' for help.

Error: Invalid value for 'BPP': 'false' is not a valid integer.

It seems to be the case that [OUTPUT] is not an optional parameter. But providing it does not work either.

Downloading and decoding a video in one step, however, does work. Why is YouBit able to do this but local decoding is not possible?

You're definitely on an older version of YouBit. Please upgrade to 2.0.0 first, the CLI should be more straightforward as well.

Yes, you were right. I downloaded version 0.1.4 and not 2.0.0. Now, everything works fine.
