but I cannot figure out how to use it to include the MPEG segments.
And MPEG-DASH manifest creation afterwards I couldn't figure out at all,

DASH is codec agnostic, so if you already have or generate the ts segments for
HLS, you should be able to generate the mpd file for DASH to play back the same
segments you would use for HLS. I have used the m4s segments, and I have seen a
common instance of lip sync issues that I have never see
Hi Clay,
for me storage is not a major concern (the total number of videos will
not be that high), but device compatibility is (including older
devices). Apple does not seem to support CMAF on older devices, only
MPEG-TS, therefore I'll stick to MPEG-TS. There are also some approaches
like
Hi Steve
Have you looked into CMAF for this solution? I am also working on some
complex transcoding and packaging actions for HLS ABR delivery. I am
looking into using CMAF to reduce the overall storage footprint (gpu/cpu
threads still cost a lot more than storage). Also, I am experimenting

Hello,
after a lot of experimentation I managed to have DASH and HLS output in
the same encoding.
Only thing I cannot get to work is not encoding the audio multiple
times: HLS cannot map a stream multiple times and while tee can
duplicate a stream to multiple outputs, it cannot duplicate a
Hello,
I would like ffmpeg to transcode a file into different versions for
adaptive streaming (different codecs, different resolutions, different
bitrates):
DASH with webm (av1, opus) and MP4 (h264, aac)
HLS with MPEG2-TS (h264, aac)
While it is easy to find example command-lines for each of
