Thanks. I do not care much about the quality. I am trying to verify
streaming HBR (high bit rate) audio via HDMI (aka HDMI passthrough,
HBR audio streams need to go through ff_spdif_muxer, implemented in
libavformat/spdifenc.c).
I've never tested spdif, but maybe below will somehow (I don't know how)
help.
ffmpeg -h full | grep spdif -A 4
spdif AVOptions:
-spdif_flags <flags> E....... IEC 61937 encapsulation
flags (default 0)
be E....... output in big-endian format
(for use as s16be)
-dtshd_rate <int> E....... mux complete DTS frames in
HD mode at the specified IEC958 rate (in Hz, default 0=disabled) (from 0
to 768000) (default 0)
-dtshd_fallback_time <int> E....... min secs to strip HD for
after an overflow (-1: till the end, default 60) (from -1 to INT_MAX)
(default 60)
