|
|
hi,
I understand by transcoding that a new media file isn't created but re-encoded on the fly and streamed to other devices. For instance rather than having to re-encode a bluray movie to a phone format what transcoding does is re-formating without saving the file. Am I right?
If so, anyone got a quick example how to do this?
thanks |

Transcoding is the process of decoding one format and re-encoding in another. You can either do this from one file to another, or from one file to a stream.
If you just want to re-encode a blu-ray into another format, ffmpeg will probably do this. I don't have any examples, though, since I use it rarely myself. _________________ Gentoo Studio in open beta. Feedback wanted. |

Transcoding is more than merely format conversion. It also includes scaling and frame rate conversion.

..and if it's an encrypted bluray dvd, then you will also need to decrypt the contents, before the de-coding and then re-coding process. There's a good bluray howto Gentoo forum thread here, you can check out for more detailed info.
Good Luck.. |
