Carl Eugen Here's my logic: If a commercial blu-ray's LPCM is big endian, then it's more likely that any/all decoding software will handle big endian (as opposed to little endian). So, if I have a transcode choice (e.g., pcm_s16be versus pcm_s16le), I choose big endian (e.g., pcm_s16be). Since the bits/sample is only 16, big endian versus little endian is not much of a performance issue. Big endian streams more efficiently, but so what, eh? I'm just trying to be convervative.

And the thread is relevant because it tells me > something that ffmpeg does not do, so I won't ask it to. Again: It is technically true that pcm_bluray stores data big-endian-wise. This information was (very) important ten years for the developer who implemented pcm_bluray support in FFmpeg, it may still be interesting to curious people (and there is nothing wrong asking about it). The fact that pcm_bluray stores data big-endian-wise is completely irrelevant when you use FFmpeg, neither when you use the command line application "ffmpeg" nor when you use libavcodec. (The big-endian fact has no relevant effect, no matter the hardware you are using nor the output format. The only effect is that the extremely fast "decoding" of pcm_bluray is in theory for some input files faster on big-endian hardware than on little-endian hardware, this will be difficult to prove because of the very high decoding speed of pcm codecs in general.) And since there were indications in this mailing list thread that the following is not completely obvious: From FFmpeg's pov, the pcm codecs are audio codecs just like mp3, aac or alac. The fact that the pcm codecs are not compressing data made implementing them (much) easier but when you are using a pcm codec (for decoding or encoding), the usage is exactly the same as if the codec would compress data.
