I think I can use mad_stream_skip to seek a new frame but I always got a lost sync error

I don't understand?

mad_stream_skip() is useful for skipping objects within the stream that have a known size, such as ID3 tags. It works by ignoring the specified number of bytes in the stream, even if they span multiple buffers.

For general seeking, you can simply pass a new buffer to mad_stream_buffer() at the point you wish to resume decoding. Note that an initial sync error is completely normal and benign.
