Summary0001069: When no source audio then don't add audio mxf to DCP
Description

When creating DCPs with no audio in the source, DOM still adds silent audio mxf although it's completely unnecessary. So I suggest not to add audio mxf in that case or give users an option to manually exclude audio mxf in the audio settings (Channels: 0 - No audio).

Maybe I am wrong, but as far as I know, some servers throw error if no audio-track. At least somewhere read about it.

So for greater compatibility I suggest adding and option to manually exclude audio track. We have Dolby servers and they accept DCPs with no audio track.

Any additional flag/checkbox means potential user irritations. If I have the spec right, at least for SMPTE, there MUST be an audio stream with picture streams.

'A Composition Playlist shall have one picture essence track and one sound essence track in each Reel element.'

I understand why some experienced people (usually including me) want all sorts of options to cater for special needs. I just think now that DCP-o-matic then should not be the place to have that, and have made my peace with that.

@scorpio81: as Carsten says, SMPTE specifically forbids this, so I think it's a bad idea. Any comments?

I'll mark this as resolved; feel free to leave comments.
