hi
i am using encode2mpeg but i am having problems with mpeg2enc
at the end of the file the program terminate.

what can i do
my system it is a 64bits Intel Xeon maybe this is the problem..

May be your source file is corrupted?
Try with different source files and see if they all cause the problem.
Also you can test on a 32 bit system and see what happens.

Hi again
i found the problem with mpeg2enc ...the problem is with -M option
in my enviroment is set to 8 i have 2 intel Xeon dual core
but in the man page of mpeg2enc i read
Setting -M 0 disables all multithreading. This is sometimes useful for
debugging or to achieve maximum CPU efficiency on a shared machine.
Setting -M 3 on a dual-CPU machine will produce slightly faster results
than -M 2 at the price of slightly less CPU efficiency. This is useful
if nothing else needs to be done on the encoding machine. In practice
there is little point setting -M greater than 4 even if the CPU's are
available due to the fairly coarse-grained parallelism used. Indeed
there is a hardcoded limit of 4 worker threads.
The default has been changed to be 0 instead of 1 to avoid the crash at
end of encoding:
INFO: [mpeg2enc] Signaling last frame = 499
mpeg2enc: seqencoder.cc:433: void SeqEncoder::EncodeStream(): Assertion `pass1coded.size() == 0' failed.
Abort
then i change M 8 to -M 0 and works perfectly
that's the problem

I wonder if I should remove totally the option -M from mpeg2enc, I have never seen any speed gain with mpeg2enc with 2 cpu. On the other hand, in Mpeg Mode you should see a real speed boost. Compare the encoding time using the option -cpu 1 and not using the option at all (using all the cpu available). Giacomo |
