On data formats in GR coding layer

Hi guys,

I have some feedback regarding data i/o formats in your coders, specifically DVB-S2 LDPC and BCH. Played around with it for a while when reading the theory of their construction and noticed that you are using bit-per-byte format instead of densely packed bits.

Why should a consumer and a user of your API be concerned about intrinsic esoteric data formats, i.e. if I give a binary bit stream, I expect Encoder block to give me encoded binary dump instead of first manually converting it to LSB's and then back to densely packed stream.

Unfortunately, to the best of my knowledge, it doesn't work this way currently.

Would be very grateful if you have some free time to answer.

KR,

Marko
