OT? test dvd for multichannel audio
by Andrew Randrianasulu 27 Jan '24

27 Jan '24

http://www.dolby.free.fr/Dvd.htm someone posted this link to wikipedia's article on MPEG multichannel (old mp2 variety). it all in French, but ISO with spinning diskette picture hopefully understanable. Around 60 mb. http://www.dolby.free.fr/Soft/Fichier%20Image%20du%20Dvd%20Test.zip

Attempt at making byteorder setting/info consistent (Big endian on the right)

right now if you encode PCm it will be Big Endiansetting on the right, but it will become left-choice if you try to load same file back into cin

From DV to MPG to DVD Video + PCM Audio
by Terje J. Hanssen 26 Jan '24

26 Jan '24

I want to showcase this procedure using alternative tools, and in case this sooner or later can be of some use for Creating DVD with CinGG.. *1. From DV Video w/native LPCM to DVD-compliant MPG using FFMpeg (version 4.4.4 on Leap 15.5) 2. From MPG w/o re-encoding to DVD structure and iso using DeVeDeNG (version 4.17.0 from packman) 3. Burn DVD iso with K3b from DeVeDe (or optional using Xorriso etc) * So far step 3 is not tested yet. Playback of the final mpg movie is tested with VLC and FFplay - not real tested with DVD disc in standalone players. *1.

Manual documentation for 1 Audio Shortcut is either wrong or confusing?
by Phyllis Smith 23 Jan '24

23 Jan '24

There is a shortcut documented in the Manual, that seems to be incorrect and is certainly confusing shown last in Bold below. Audio Attach Trans. --- Open audio transition select for insert at edit boundary. Attach Effect. -- Open audio selection menu for insert at edit boundary. *Render Effect -- Open audio render select to render from select as pcm.*
