Unique images for audio files

[tommyneu]

Currently audio uses a default image file for all audio. It would be nice to be able to generate a waveform image of the audio. This is done on the frontend after the audio starts but not on the backend when the audio is uploaded.

M4a audio files also supports album art so it would be nice if it had that pulled into the default thumbnail

Looks like there is some ffmpeg commands that will generate the waveform image file from an audio file

Example command:
ffmpeg -i input_audio.mp3 -filter_complex "aformat=channel_layouts=mono,showwavespic=s=1280x720:colors=red,drawbox=x=0:y=360:w=1280:h=1:color=red" -frames:v 1 output_waveform.png

Users would like the option to choose whether or not to display the waveform/poster for audio files.

@sarongebre I think on mediahub we would want it to be with the waveform. That way the user experience is the same across all audio media on mediahub. I think embed wise that would be a good option if the person wanted it or not
