Hi community,
ffmpeg options are a bit daunting for me. Can anyone teach me how to
transcode to high bitrate of Dolby TrueHD or DTS-HD Master?
I download testing samples from here:
http://www.demo-world.eu/2d-demo-trailers-hd/
Cavalcade (Lossless) (DTS-HD MA 5.1), ffplay can play it with no
problem, ffplay shows its audio bitrate is 1536 kb/s.
Can someone teach me how to transcode this .m2ts file to high
bitrate audio (e.g. max 24.5 Mbps for 5.1 channels, 192k sampling
rate, 24 bits, 5.1 channels) (i: still attain the video stream, ii,
audio only)?
There isn't support for DTS-HD MA currently. ffmpeg/play will use the
normal DTS core.
TrueHD is supported, though I think you will get full dynamic range,
which is not ideal. The same seems to be true for DTS.
Thanks Andy. Any idea what is the command line to resample TrueHD from
like 640kbps to HBR (>6.144Mbps)?
