-Subject: Check the size before reading with mad_bit_read
-
-There are various cases where it attemps to read past the end of the buffer
-using mad_bit_read(). Most functions didn't even know the size of the buffer
-they were reading from.

-From: Kurt Roeckx <kurt@roeckx.be>
-Date: Sun, 28 Jan 2018 15:44:08 +0100
-Subject: Check the size of the main data
-
-The main data to decode a frame can come from the current frame and part of the
-previous frame, the so called bit reservoir. si.main_data_begin is the part of
-the previous frame we need for this frame. frame_space is the amount of main
-data that can be in this frame, and next_md_begin is the part of this frame that
-is going to be used for the next frame.
-
-The maximum amount of data from a previous frame that the format allows is 511
-bytes. The maximum frame size for the defined bitrates is at MPEG 2.5 layer 2
-at 320 kbit/s and 8 kHz sample rate which gives 72 * (320000 / 8000) + 1 = 2881.
-So those defines are not large enough:
- # define MAD_BUFFER_GUARD 8
- # define MAD_BUFFER_MDLEN (511 + 2048 + MAD_BUFFER_GUARD)
-
-There is also support for a "free" bitrate which allows you to create any frame
-size, which can be larger than the buffer.
-
-Changing the defines is not an option since it's part of the ABI, so we check
-that the main data fits in the bufer.
-
-The previous frame data is stored in *stream->main_data and contains
-stream->md_len bytes. If stream->md_len is larger than the data we
-need from the previous frame (si.main_data_begin) it still wouldn't fit
-in the buffer, so just keep the data that we need.
