pyglet-ffmpeg's Issues

"Unable to find match for ffmpeg sound library at expected location"

Using Arcade, Python3, and Ubuntu, this library is looking for ffmpeg .so files in the wrong location.

https://stackoverflow.com/questions/60446410/trying-to-use-the-arcade-library-on-python3-with-debian-10-errors-with-pyglet-ff/60857807#60857807

Instead of it being found at

~/.local/lib64/python3.7/dist-packages/pyglet_ffmpeg2/linux_x86_64/libavcodec.so.58.*

it was found at

~/.local/lib/python3.7/dist-packages/pyglet_ffmpeg/linux_x86_64/libavcodec.so.58.*

import pyglet_ffmpeg2 error

This is the code;

import pyglet_ffmpeg2

print("asd")

and the traceback gives me this:

During handling of the above exception, another exception occurred:

Error -13 returned when loading media from io.Bytes on Windows

Problem:
on Windows 10, when calling -
pyglet.media.load(io.Bytes(media_data_as_byte_array), streaming=False, decoder=pyglet.media.codecs.ffmpeg.FFmpegDecoder)
I get the following error: pyglet.media.codecs.ffmpeg.FFmpegException: avformat_open_input in ffmpeg_open_filename returned an error opening file C:\Users\user\AppData\Local\Temp\tmppgpnk36v Error code: -13

Debugging the problem:
When FFmpegSource is constructed in ffmpeg.py it creates a named tempfile which the media_data is written to. However the tempfile is 0 bytes, and cannot be opened by ffmpeg because python still has it open. Reading the docs about NamedTemporaryFile, it mentions that on Windows the tempfile cannot be opened by a second process unless the file is first closed by Python (which would remove the tempfile).
If I change the constructor to not delete the tempfile, write the data and then close the tempfile before ffmpeg loads the data then it works. But leaves the tempfile on disk.

        if file:
            file.seek(0)
            self._tempfile = tempfile.NamedTemporaryFile(delete=False)
            self._tempfile.write(file.read())
            self._tempfile.close()
            filename = self._tempfile.name

Provide a selftest option to help debug/diagnose

Since this is so fiddly, we need an easy thing to tell people to do as a diagnosis. As an example, if you tell them to do this:

$ python3 -m pyglet_ffmpeg.selftest

...it could play a bundled sound file for each supported format, then dump some information about the location of the binaries, etc.

bumpversion errors

Trying to use bumpversion, I ran in the following issue TypeError: environment can only contain strings.

I found the following issue in their issue tracker: peritus/bumpversion#67

According to the last message, the development is rather inactive but there is another fork from this project bump2version.

Any chance to investigate if this could replace the actual bumpversion?
