Ad hoc FAQ, started by Bram Stolk Suggestions to: b.stolk at chello.nl Q) Why are my MPEG files 0 bytes long? A) Maybe there is no valid PAL/NTSC signal present. Check cables, and check input setting svideo/coax. You may need to reload the kfir module to change to/from coax. Q) What kind of streams are generated? A) For MPEG2, the default stream is composed as: I BB P BB P BB P BB P BB Q) Why does the build process fail for me? A) Maybe you already have i2c and v4l linux stuff in your kernel and on your system, which may interfere with the building of the optional modules. Uncomment the $(MX_OBJS) part in line 6 of driver/Makefile like this: obj-m = $(M_OBJS) # $(MX_OBJS) Q) How can I edit the mpeg streams? A) Kees Cook's GOPChop is an excellent choice. See http://outflux.net/unix/software/GOPchop/ GOPChop works just fine with kfir generated streams.
