Would it offer a benefit over ffmpeg?Įl Heggunte, I'm sorry to admit I have no idea what to do with that decimal value chart. mp4 container ultimately I'll be muxing this with an. Total length of the 5.1 track is over 2 hours, and at 24 bit, the size is too much for a wav container (over 6GB, exceeding the 4GB limit). Unfortunately I can't use a wav container for the 5.1 due to file size. Is FFmpeg doing some strange behind the scenes channel layout? Or is this a playback issue related to reading the files and their metadata or headers?Ĭan one specify channel layout in FFmpeg, beyond what I've already did unsuccessfully with the mono files (see below)? Using FFmpeg to make a 5.1 file from 6 mono wavs with the channel layout mapped for SMPTE "L R C LFE Ls Rs", aka 5.1(side), I get a file that FFmpeg tells me is "5.1" - NOT "5.1(side)" - and it also has the "center channel playing through the left speaker" problem.
It sounds like, at the very least, the center is playing through the left channel speaker. mov file that FFmpeg tells me is "5.1(side)" and it does not play fine. dts file to FLAC via FFmpeg, I get a 5.1 FLAC file that FFmpeg tells me is "5.1(side)", and it plays fine. MPC-HC plays everything correctly, but because the other two have playback issues, I presume there's something incorrect with the files.įFmpeg tells me that the channel layout of the original DTS-HD file is "5.1(side)" (which is, as I understand it, SMPTE "L R C LFE Ls Rs").
VLC and Quicktime seem to reproduce most if not all of the same errors. I've been experiencing some playback problems with 5.1 files converted from a 5.1 DTS-HD source using FFmpeg (scrambled channel layout). Mediainfo's "Channel positions" (not the same as " channel layout" apparently) tells me "Front L C R, Side L R LFE" no matter what file I give it, and for files whose channel layout's are certainly different. What's the best way to determine a 5.1 file's channel layout?
