Re: [FFmpeg-user] Error decoding DTS-HD MA audio files
I have now ripped the whole Vol 1 of the first BluRay (87 tracks) with the 'direct stream demux' method and then converted to flac with ffmpeg using your command parameters. The resulting flac files play ok. Most transitions are perfectly gapless, but there are a few that have a slight click at the track change (amongst others between 5 and 6). Next, I tested playback with my Oppo BDP93 via HDMI to an Onkyo AVR. Interesting result. Playback is @192kHz and gapless. However when I skip to tracks 5 and 6 (who both showed issues when converting to flac), the Oppo counter increments (showing playback in progress), but output stays silent. If I play tracks 4, 5 and 6 in one go without skipping forward, playback is ok and gapless. So there definitely seems to be a production issue on DG's side. Your workaround is priceless, thank you. I will now get back to Deutsche Grammophon to see if I can get the 192kHz files as a download from them Best regards Rudi -Original Message- From: ffmpeg-user On Behalf Of Paul B Mahol Sent: Friday, 26.

Re: [FFmpeg-user] Error decoding DTS-HD MA audio files
Thanks, Paul
You are a genius. Your command worked with the two files I had sent you. I am
now getting playback on the dCS Rossini from the beginning and (as far as I can
hear) gapless playback between 4 and 5.
However, I still have an inkling that not all is well
I have attached the log of the two conversions that I did. Chapter 4 seems to
convert ok with some messages but (as I see it) nothing serious. However
Chapter 5 (the one that previously converted to 48kHz) has some serious error
messages. Playback of the flac file seems ok.
The dts file was extracted from the BluRay using DVDAE and the 'direct stream
demux' option. Ffmpeg has more issues with some extracted "dts files than with
others. Could it be that the issue is already at the stage of the 'direct
stream demux' option?
As I am getting exactly the same results (same files extract @48kHz) using
MakeMKV / MMH, there could be a problem at the ripping stage of the BluRay and
not primarily with ffmpeg? What do you think?
Best regards
Rudi

The Chapter 5 file dts-hd-ma have certain delay. Thus you get with ffmpeg first
few frames in only dts core at 48kHz 16bit and later full dts-hd-ma kicks in
with 192kHz and 32bit, but because filtering is not supporting changing of
sample rate and/or sample format at runtime all remaining frames are filtered
back to 48kHz and 16bit. This is evident if you run ffmpeg with '-v debug'
flag.
Workaround is to force filtering at 192kHz and 32bit right at start with this
command:
ffmpeg -i Title1\ -\ Chapter\ 05.dts -af aformat=f=s32p:r=192000:cl=stereo
out.flac

Hardware playback of 24bit flac at 192000 Hz is not widely supported AFAIK.
