Sebastii, can you please either add documentation for this in the wiki yourself, and/or get in contact with one of our docu members, so we can have this properly documented. Or just ask on IRC to get assistane with this.
This also requires new language entries (en/fr provided), we need to handle this too.
Seb did a great job by adding thie new ability to mp. But maybe it is time for mp team to develop this idea deeper? i.e. it will be better to switch edition with other splitters like gabest or lavf. so maybe you can watch ffmpegsource code in search of editions switching code there?
Thanks.
