Michael Niedermayer 0667c14ad6 avcodec/g729dec: require buf_size to be non 0 The 0 case was added with the support for multiple packets. It appears unintended and causes extra complexity and out of array accesses (though within padding) No testcase Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit `f64be9da4c`) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>		2020-01-06 11:30:44 +01:00
