[FFmpeg-devel] [PATCH v1 1/1] avcodec/vorbisdec: Return value check for init_get_bits

[maryam ebrahimzadeh]

avcodec/vorbisdec: Return value check for init_get_bits

As the second argument for init_get_bits can be crafted,
a return value check for this function call is necessary.
Also replace init_get_bits with init_get_bits8.
