What is your specific problem? Are there more errors
in the frame than the fec can allow for correcting?
Are you doing the product code decoding properly?
Is the frame an i-frame?
When there are more errors than can be corrected,
meaning a non-trivial syndrome yet no error locations,
then the decoder will bail-out, the block has members
which will tell you the number of errors detected,
corrected and if the codeword was successfully "decoded".
The examples in the library clearly show how this can
Be one who knows what they don't know,
Instead of being one who knows not what they don't know,
Thinking they know everything about all things.
