avformat/dashenc : Add framerate to dash manifest
18 novembre 2015, par Bryan Huhavformat/dashenc : Add framerate to dash manifest
DASH manifest should have framerate specified as an attribute in the
AdaptationSet element and Representation elements. Though ISO/IEC
23009-1:2014 doesn’t seem to define frameRate as a required attribute,
it is at least optional, and DASH-IF IOP 3.0 seems to require it. See
section 3.2.4 of http://dashif.org/w/2015/04/DASH-IF-IOP-v3.0.pdfIn the event that avg_frame_rate is not set in the muxer, we ignore the
frameRate tag altogther.Signed-off-by : Michael Niedermayer <michael@niedermayer.cc>

FFmpeg conform DASH to YouTube Live Stream requirements
4 septembre 2023, par Aniol PagèsI'm trying to stream to YouTube using FFmpeg and DASH. I've generated the stream key and I'm successfully sending the generated files to YouTube. However, YouTube refuses the MPD manifest because it has two AdaptationSet (one for video and one for audio), and the documentation specifies that I should use only one for both video and audio


I've tried to use the
-adaptation_sets
flag unsuccessfully, and also the-map
flag.

Here is one of the commands I've tried :

ffmpeg -re -i "/Users/user/Desktop/file.mp4" \ -map 0:v -map 0:a \ -use_template 1 -use_timeline 1 -window_size 5 -min_seg_duration 5000000 \ -f dash dash.mpd


And with the
-adaptation_sets
flag :
ffmpeg -re -i "/Users/aniolpages/Desktop/2023-09-03 Taller colar filtrar assubtilar.mp4" -map 0 -map 0 -c:a aac -c:v libx264 \ -use_timeline 1 -use_template 1 \ -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" \ -f dash dash.mpd


Has someone been successful to conform the manifest to YouTube requirements ?


Thank you very much !

Create MPEG-DASH Initialization segment
5 janvier 2016, par MahoutI am looking to convert between HLS and MPEG Dash. I do not access to the original fully concatenated video file, only the individual HLS segments.
In doing this transformation to MPEG Dash I need to supply an initialziation segment for the Dash manifest .mpd file.
My questions are :
- What is the structure of a Dash video initialization segment ?
- How can I generate/create one without the need for the original full file ?
Perhaps a solution would involve getting
MP4Box
to convert the ’.ts’ HLS segments to Dash ’.m4s’ segments which are self initializing, but I am unsure how to go about this this ?Any ideas are much appreciated.
Many thanks.
UPDATE :
Snippet to stream using original hls segments. Video plays all the way through but is just black.<representation width="426" height="238" framerate="25" bandwidth="400000">
