Here are the results of some others tests : 1) Split the Dolby E Stream in Wav container into two mono Wav container > merge both mono Wav container into a stereo Wav container > wrap into u8 raw data -> Works well and the Dolby E stream is recognized by ffprobe, but still at 44800Hz. 2) Split the Dolby E Stream in Wav container into two mono Wav container > put both mono Wav container into a MXF wrapper with video > extract both mono Wav container from MWF wrapper > merge both mono Wav container into a stereo Wav container > wrap into u8 raw data > Works well and the Dolby E stream is recognized by ffprobe too, and still at > 44800Hz. Now I need to fix ffplay to play the raw data and check if sound is OK, or if the sample rate mismatch is an issue for it.
