Public bug reported: mutagen.mp4.MP4 container does not accept a string value for freeform text tags, but expects (and returns) a bytes argument. This is inconsistent with python3 default of string values.
code: >>> import mutagen.mp4.MP4 as MP4 >>> m = MP4() >>> m['----:test:item'] = 'test value' Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3/dist-packages/mutagen/_file.py", line 75, in __setitem__ self.tags[key] = value File "/usr/lib/python3/dist-packages/mutagen/mp4/__init__.py", line 375, in __setitem__ self._render(key, value) File "/usr/lib/python3/dist-packages/mutagen/mp4/__init__.py", line 391, in _render return render_func(self, key, value, *render_args) File "/usr/lib/python3/dist-packages/mutagen/mp4/__init__.py", line 632, in __render_freeform data += v TypeError: can't concat str to bytes >>> m['----:test:item'] = b'test value' >>> m['----:test:item'] b'test value' >>> Expected behaviour: accept (and return) string values, with encoding to utf-8 if required (this is implied in some of the comments in the code).
