Hi, I've committed a couple of cdrdao related files which implement the sub-channel writing. Currently, this only works with the 'generic-mmc' and 'generic-mmc-raw' driver. If someone on the list wants to try it out you'll need track images that already contain RW sub-channel data. In the toc-file the sub-channel mode must be defined with the 'TRACK' statement: TRACK <main channel mode> [ <sub-channel mode> ] <sub-channel mode> may be o RW : the track image contains plain RW sub-channel data (additional 96 bytes per block) o RW_RAW: the track image contains already encoded (raw) sub-channel (additional 96 bytes per block) If the recorder is just able to write raw sub-channels cdrdao will encode given plain RW sub-channel data. There is a new driver option for the 'generic-mmc' driver: 0x80: indicates that the recorder does not support writing plain RW sub-channels, cdrdao will do the encoding and write them in raw mode Please note that this new feature had a major impact on the basic infrastructure of cdrdao so that now also the old non sub-channel writing modes might have problems. The next steps will be implementing PQ sub-channel writing (only with the 'generic-mmc-raw' driver) and the extraction of sub-channel data with the read-cd command.
