• process recorded data from Oak-D without access to Oak-D

Hi asif
You could use the SDK to record multiple inputs. Examples should point you in the right direction. I'd suggest recording everything you need into a mcap or rosbag, which you can then recreate when testing.

More documentation.

Hope this helps,
Jaka

      @jakaskerl I get the following error while running rosbag_record.py

      oak.record([left.out.encoded, right.out.encoded, stereo.out.depth, imu], 'records', record_type=RecordType.DB3)

      raise AttributeError(name) from None

      AttributeError: DB3

      I get the following error while running mcap_record.py

      from mcap.mcap0.writer import Writer as McapWriter

      ModuleNotFoundError: No module named 'mcap.mcap0'

      This example looks suitable to solve the problem but I get the following error:

      ImportError: cannot import name 'EncodingQuality' from 'depthai_sdk' (/home/tface/.local/lib/python3.10/site-packages/depthai_sdk/init.py)

      Can you please help to resolve this issue?

        Hi asif
        Could you update to the latest version of depthai_sdk please?

        Thanks,
        Jaka

            jakaskerl I uninstalled the previous version and pip install depthai-sdk==1.10.1

            But it doesn't solve the problem.

              Oh, sorry, didn't realize it was an experiment script. The script is running on sdk==1.2.3. You should install the requirements from requirements.txt before running it.

                After following installation instructions on https://docs.luxonis.com/projects/api/en/latest/install/ and installing requiremtns, still I get the same error. ImportError: cannot import name 'EncodingQuality' from 'depthai_sdk' (/home/tface/.local/lib/python3.10/site-packages/depthai_sdk/init.py)

                Can I use the same experiment without using "EncodingQuality"? For example, we can replace "checkQuality" by a constant (what is that constant?) in the following line:

                parser.add_argument('-q', '--quality', default="HIGH", type=checkQuality, help='Selects the quality of the recording. Default: %(default)s')

                While running https://github.com/luxonis/depthai/blob/main/depthai_sdk/examples/recording/stereo_record.py, it can visualize color and depth streams but cannot write to disk due to the following error. Even after pip install av, it cannot write to disk.

                import av as av

                ModuleNotFoundError: No module named 'av'

                  @asif

                  python -m pip install av
# Or, install depthai-sdk version that includes recording;
python -m pip install depthai-sdk[record]
