Hello again Ross,
Thank you so much for the pointer, I was able to get it running very easily
right away thanks to your help.
What I did is the following.
In the ByteStreamFileSource.cpp file, I found the if that checks for the EOF.
This if also checked for a file error, so I detached both checks in two
separate if statements.
Then I simply call the rewind function on the stream if the EOF is reached, and
it simply restarts at the beginning.
So instead of this in the code:
if (feof(fFid) || ferror(fFid) || (fLimitNumBytesToStream &&
fNumBytesToStream == 0)) {
handleClosure();
return;
}
I have the following:
if (feof(fFid)) {
rewind(fFid);
}
else if (ferror(fFid) || (fLimitNumBytesToStream && fNumBytesToStream == 0)) {
handleClosure();
return;
}
Thank you so much for your help, it is really greatly appreciated!

Hello Ross,
Thanks for the information, I will see to try and implement that tomorrow (I am
in France and it is the end of the day for me).
Thanks again so much for the help.

You would basically need to implement a class - similar to the existing class
“ByteStreamFileSource” - that handles EOF of the input file differently.
Instead of calling "handleClosure()” (which would tell the downstream reader
that the data source has ended), your subclass would instead:
- clear the EOF, and
- seek back to the beginning of the file to allow file read handling to
continue as before.
