Tvheadend

Please consider switching Tvheadend to using libdvbcsa instead of FFdecsa.

libdvbcsa (http://www.videolan.org/developers/libdvbcsa.html) has a number of advantages:
Atheros AR7161
- It is faster (higher throughput in packets(#Mbits)/sec), important for use on low-end or embedded hardware
- It works on both big-endian and little-endian architectures, verified on Atheros AR7161 (big-endian MIPS) router
- It is being actively development/maintained, while development of FFdecsa seems all but halted

There are some minor problems:

API difference. While both libraries have a concept of 'packet clusters' (array of pointers to packet info), FFdecsa uses the raw packet data, while libdvbcsa uses the packet payload(sp?) meaning one has to add a 4-byte offset.
Also, libdvbcsa doesn't have a concept of 'even' or 'odd' keys, it can decrypt a packet cluster with any given key. One needs to manually assign packets to 2 clusters, one for 'even', 'one' for odd key decryption.
Also, libdvbcsa is normally an Autotools project, so the integration in standalone Tvheadend will need to be done.

Kind regards,

Alain
