Dear Ravi:
question 1:
if i want intergrate other audio codec in opencore 2.0 such as
qcelp in 3gp/3g2 file, how can i modify mp4 parser to let it work?
this audio codec omx components are perpared, new codec types are
already define in pvmi\pvmf\include\pvmf_format_type.h, any where i
can add this codec is added
if you have any sugestion , pls let me knew
question2:
to enable looger i use cmd below
rm -rf out/target/product/generic/obj/include/libpv
make -j ENABLE_PV_LOGGING=1
but i find it cannot compile through, a lot of killed appears, why?
looking farward for your kindly reply.
