Trancoder Operation

[MrD]

Is the transcoder usage defined anywhere?

I understand how to turn it on, and the DIVx streams are pretty intuitive, but what it is DVD config for, how is it used?

Also, is there anyway to *force* an MPEG2 PS to go through the transcode server (i.e. a VOB is an MPEG2 PS)

I believe "DVD" refers the the MPEG-2 profile used for encoding, not to anything dealing with DVD rips. I don't believe there's currently a way to force MPEG-2 through the transcoder.

[MrD]

I didn't expect DVD to refer to DVD rips, but if DVD refers to the encoded program, then why would it need to be transcoded for the MVP?

And since Sage creates MPEG-2 PS then everything (including) VOBs should go through this transcoder. But this is not what I am experiencing. Sage is recognizing the MPEG-2 PS as a native format and sending it straight to the MVP.

I think you missunderstand, the transcoder is encoding the video into an MPEG stream. DVD is the quality (preset) at which the mpeg encoder operates. It has nothing to do with the source files.

Please explain what each property does

media_server/transcode_quality/DVD=
media_server/transcode_quality/MPEG4-128K=
media_server/transcode_quality/MPEG4-256K=
media_server/transcode_quality/MPEG4-384K=
media_server/transcode_quality/MPEG4-Full-384K=

I am assuming that the arguments to the right of the equals are passed to ffmpeg (the transcoder). So how does Sage know which row to select for a particular type of video file?

My guess would be that they don't apply to the MVP (there for future use?)

Or maybe with the miniclient/transcode_mode property.

Really have no idea.

I was hoping someone would jump in before I really display my ignorance on this subject

The first is for the mvp client, it always uses these parameters for the mvp. I think they could have called it mvp instead of dvd, the otehr lines are for the place shifting web client, that was shown at the CES. (Oh and in case you wondered, yes I tried wether that web-client was in the beta release, but couldn't find anything, although sage was listening on some ports ;-) )
