Creating farms of unique websites

This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

MSE Does not show duration when MPEG-DASH segments are created with FFmpeg
15 mars 2023, par WaveLinkI am trying to create a system that streams DASH segments to the browser, where it gets decoded by Media Source Extensions. When using MP4Box, the init segment loads the duration into the player, but the version generated by FFmpeg does not.


I believe this is due to some sort of header missing from the init segment generated by FFmpeg, but I have not been able to figure it out. Here is the command I use to generate the files :


ffmpeg -i .\source.opus -c:a libopus -c:v none -seg_duration 1 -dash_segment_type mp4 -preset ultrafast -use_timeline 1 -use_template 1 -streaming 1 -init_seg_name "segment_init.mp4" -media_seg_name "segment_$Number$.m4s" -fflags +genpts -f dash ./out.mpd

When using MP4Box, this is the config I use :

MP4Box -dash 1000 -rap -profile live -segment-name "segment_$Number" .\out.mp4

In both cases, the audio does play, and both of them contain similar headers, but the FFmpeg version just does not contain the media duration in the init segment, or at least the MSE implementation cannot read it.

I tested this in Chrome, Firefox, and Edge, and all of them behave the same.


Thanks for any help.

How to generate MPEG-DASH stream with ClearKey DRM using FFmpeg
15 juillet 2020, par QFSWI want to create an MPEG-DASH stream with ClearKey DRM using FFmpeg.


The stream generation is already complete and working (using the C API)


How could I (using either C or the CLI) add ClearKey DRM to the stream ?


Happy to hear answers for both VOD and live as a pointer to get started
