Here's the problem: the lavc encoder is getting reinitialized in the middle of the encode due to changing header properties in the source file. Try using lavc for decoding (-vc ffmpeg12) and see if the problem goes away. This is a bug that needs to be fixed, but I don't know enough to deal with it. ------------------------------------------------------------

Thanx, -vc ffmepg12 helped.
------------------------------------------------------------
Try that, see if it works. If not we'll have to delve deeper, and if the problem is as complex as the above description implies - ie a long way from the buffer allocation code, deep in the structure of the data stream - I'm probably not going to find it.

So
" Cannot find codec 'mpegvideo' in libavcodec..."
is the problem with the CL ?
Heres what man mencoder says about it,
-vc <[-]codec1,[-]codec2,...[,]>
Specify a priority list of video codecs to be used, according
their codec name in codecs.conf. Use a '-' before the codec name to omit
EXAMPLE:
-vc divx
force Win32/VFW DivX codec, no fallback
so I don't see what was wrong with the CL,
it must be inside libavcodec where the problem lies.
There are of course mpegvideo.c mpegvideo.h mpegvideo.o the question is are these what it is looking for ?
I would of thought so, but ?
The question is whether these are the codecs it wants under a command ffmepg12 which I took to mean mpeg 1 and 2 ,not sure what ff is a symbol for.
Incidentally did you notice the low 19fps , in my experience something more like 29fps is normal, but for all I know 19fps may be ok.
As for the explanation given , I can hold with the concept of "the lavc encoder is getting reinitialized in the middle of the encode due to changing header properties in the source file" as this would make sense against the fact that mencoder does not habitually fail encoding mpeg2 to mpeg4 , as I have said before it's about a 20 to 40% failure rate and to my mind that is consistent with the varying nature in the way that DVD's are assembled. There simply in no absolute standard for dvd's each packagers does their own thing within general overall concepts.So when mencoder finds on the source CD the kind of setup with definitions it fully understands it goes on to complete the task and include an index file, but when mencoder finds a CD whose packaging is not exactly wrong, as such, but not exactly the definition it is expecting to find it fails to build a satisfactory result with all it's components , that is it seems to build the necessary video and audio codec files but cannot create an index that can be run by any programme that is required to look for one.
Mplayer gets around the problem by searching the divX CD and creating a temporary index file in memory for the programme to use, but this is fast becoming unsatisfactory, as dixX dvd players are here to stay and they don't have the index building capability mplayer has.
So, to sum up, yes it does seem to be a "read error confusion" in that mencoder is having problems handling the variable nature of DVD CD's and yes I do think it needs fixing.Needless to say that is beyond my abilities. Still, I can help identify the problem, and that is half the battle.
If you think I did the CL wrong, let me know,
John
