For decoder developement.
Thank you!

Do you believe there is a need to decode LPCM? Or you have something else in mind?

P.S. I cannot do Chinese ;)

Is it that you have such data in a file and need to know the format (header, endian, etc.) or do you need to extract the LPCM audio from the disc itself?

Take this .ts for example: Halloween.Blu-ray.REMUX.1080P.H264.LPCM.DD51-SiLU.disk1.ts
That I know the audio track is LPCM format, and the demuxer will feed the audio es to audio decoder.
But How the decoder recognize the PCM format, like endianess, sampling rate, bit per sample, channel setting, and other elements.

Thank you!

btw: I'm developing audio decoder used in set-top box chip.

the former, like header format, sampling rate and so on.
