Returns process status - and the captured output. - - The parameter ``t`` is a table. The function reads the following entries: - - ``args`` - Array of strings. The first array entry is the executable. This - can be either an absolute path, or a filename with no path - components, in which case the ``PATH`` environment variable is - used to resolve the executable. The other array elements are - passed as command line arguments. - - ``cancellable`` - Optional. If set to ``true`` (default), then if the user stops - playback or goes to the next file while the process is running, - the process will be killed. - - ``max_size`` - Optional. The maximum size in bytes of the data that can be captured - from stdout. (Default: 16 MB.) - - The function returns a table as result with the following entries: - - ``status`` - The raw exit status of the process. It will be negative on error. - - ``stdout`` - Captured output stream as string, limited to ``max_size``. - - ``error`` - ``nil`` on success. The string ``killed`` if the process was - terminated in an unusual way. The string ``init`` if the process - could not be started. - - On Windows, ``killed`` is only returned when the process has been - killed by mpv as a result of ``cancellable`` being set to ``true``. - - ``killed_by_us`` - Set to ``true`` if the process has been killed by mpv as a result - of ``cancellable`` being set to ``true``. + and the captured output. This is a legacy wrapper around calling the + ``subprocess`` command with ``mp.command_native``. It does the following + things: + + - copy the table ``t`` + - rename ``cancellable`` field to ``playback_only`` + - rename ``max_size`` to ``capture_size`` + - set ``capture_stdout`` field to ``true`` if unset + - set ``name`` field to ``subprocess`` + - call ``mp.command_native(copied_t)`` + - if the command failed, create a dummy result table + - copy ``error_string`` to ``error`` field if the string is non-empty + - return the result table + + It is recommended to use ``mp.command_native`` or ``mp.command_native_async`` + directly, instead of calling this legacy wrapper.
