Uncompressed PCM audio in MP4?

F J Walter · 5th September 2008, 01:55

Is it possible to use a PCM audio stream in an MP4 container?

If it is possible, what formats are supported/recommended (ie signed/unsigned, bit depth, endianness)? Would playback be supported by the majority of players, including current and future hardware/embedded players?

The reason I ask is that I can't find a way to add PCM audio to MP4 using ffmpeg, which kind of tells me I am trying to do something unsupported. Looking at various websites about MP4, PCM audio isn't listed as being officially supported (though Apple lossless is...?)
