Hi Alvaro,you should be able to generate the mpd file for DASHYes, but how? ffmpeg proved an easy way to generate webm-dash-manifests,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,only with at least remuxing the files.

I have used the m4s segments, and I have seen a common instance of lip sync issues that I have never see using mpeg.ts segments. In my opinion, CMAF using mp4 segments is over-rated, and heavily promoted by commercial encoding and streaming engines like Wowza.Regards, Alvaro JiménezOn Tuesday 11 October 2022 10:06:36 AM (-07:00), Stefan Oltmanns wrote:Hi Clay,for me storage is not a major concern (the total number of videos willnot be that high), but device compatibility is (including older devices). Apple does not seem to support CMAF on older devices, onlyMPEG-TS, therefore I'll stick to MPEG-TS. There are also some approacheslike mux.js that are intended to remux the stream as needed in the browser, but I rather stick to MP4/MPEG2-TS. I have not played with ffmpeg-python yet, but good to know. I started writing a PHP script that generates a ffmpeg command-line for transcoding a specific video (in fact multiple, because ffmpeg gotkilled when I tried to transcode to all formats at once: my system ranout of it's 64 GB memory...).I still couldn't figure out how generate a single DASH manifest for webmand mp4 files. That should be possible, because dash.js added support for that in 4.0 and shaka seems to have always supported that.
