/* This is a debug tool used to detect bitstream error. On encoder side, it
|
|
* pushes each bit and probability into a queue before the bit is written into
|
|
* the Arithmetic coder. On decoder side, whenever a bit is read out from the
|
|
* Arithmetic coder, it pops out the reference bit and probability from the
|
|
* queue as well. If the two results do not match, this debug tool will report
|
|
* an error. This tool can be used to pin down the bitstream error precisely.
|
|
* By combining gdb's backtrace method, we can detect which module causes the
|
|
* bitstream error. */
