Hi! Somebody knows any way to demux scrambled MPEG-TS with FFdecsa descrambler (or other DVB-CSA descrabler) ? So, i think that I need to add read callback to MPEG-TS demuxer: my_descrambler(uint8_t* buf, int buf_size); where buf - is 188-aligned buffer How to add this callback without patching sources of the FFmpeg?
