Include audio track in video file, instead of separate audio file

[achimmihca]

Hi, thanks for this neat tool! Here is an idea:

• Why download a separate audio file? Instead, the video could just include the audio track.
  • This would reduce download size and require less disk space.
  • AFAIK, all popular UltraStar games can already handle a video file in the #AUDIO header.

So, my suggestion:

• Add a new option in the video format settings to use video file also for audio.
  • When enabled, the #AUDIO header is set to the video file.
  • There is already an option to not download the audio file. One could reuse this option, but I think a dedicated option makes more sense.

What do you think?

Thanks for the suggestion. Indeed, you get the best quality if you download audio and video separately. They could subsequently be muxed into a single file, but a) this would not save any disk space b) takes additional time for no benefit other than having one file less. AFAIK only USDX supports reading the audio track from a video file (maybe also Performous and Play?).

There could be an option to download a combined audio+video file at the expense of lower quality (this would indeed reduce download size and disk space) and at the expense of potentially limited support by karaoke softwares, but currently I do not see the advantage for that (I'd rather go for muxing the two files after download, and there's already an experimental Syncer addon for that).

maybe also Performous

Yes: Performous supports reading audio track from a video file.
