What options are there for getting a yuv stream from
divx or DVD movie? When encoding to SVCD, I use transcode
basically for that.

Is there a tool for splitting mpg files?
The MPEG program stream (mpg) was not

I want to use mjpegtools from cvs, because of the

How can I find if the source is interlaced?

I am in doubt about the aspect ratio. For svcd, after

Hello.
Does the option "-R" used with mpeg2enc have
any influence in the quality of the transcoded
video stream? If I am not wrong, in old versions
of mjpegtools the default is "-R 2" and in the
latest one it is "-R 0", which speeds up
INFO: [mpeg2enc] Assuming non-video stream of 285 Kbps
So the problem should not be with transcode, as mpeg2enc
knows that it should start a new sequence every 804 Mbytes.

It is capable of adding text and special effects to YUV
video streams and allows the construction:

It looks a nice application. Just trying it.

I
miss the opportunity of putting the subtitles
in the bottom black border unless I do that
after the scaler is run. Then I would need this
program I am looking for.
Maybe y4mscaler or mpeg2enc could have this feature
themselves.
Any thoughts about this?

Unfortunatly I do not have the log file of the previous erroneous
