Ticket #4918: libs_libmythtv_mpeg_tspacket.h-move-AFCOffset-to-TSPacket.patch

File libs_libmythtv_mpeg_tspacket.h-move-AFCOffset-to-TSPacket.patch, 1.3 KB (added by Erik Hovland <erik@…>, 18 years ago)

Moves AFCOffset to TSPacket so that we don't have funny indexing of _tsdata

  • libs/libmythtv/mpeg/tspacket.h 

    Since AFCOffset uses a strange off index value it should be moved to TSPacket

From: Erik Hovland <erik@hovland.org>

instead of TSHeader
