假设我有这个元组:
(<GstStructure at 0xb270e080>, ' audio/x-raw, rate=(int)44100, layout=(string)interleaved, format=(string){ S8, S16LE, S32LE, S24LE, F32LE, F64LE }, channels=(int)[ 1, 2147483647 ]; audio/x-raw, rate=(int)[ 1, 2147483647 ], channels=(int)1, format=(string)F32LE, layout=(string)interleaved; audio/x-raw, rate=(int)[ 1, 2147483647 ], layout=(string)interleaved, format=(string){ S8\x91\x00\x00\x00@\x00p\xb2@\x00p\xb2LE, S24LE, F32LE, F64LE }, channels=(int)[ 1, 2147483647 ]')
我想得到率,但元组真的只有两个元素。我怎样才能得到利率?
