webm dash encoding... What are the correct ffmpeg parameters ?
24 avril 2020, par DeanI'm stumped with encoding videos into a dash compliant format. I'm going from .mp4 to .webm



Firstly, I am running OS X and ffmpeg 2.5.4.



Here's the encoding commands I am using in my test (I got these from here) :



ffmpeg -i IMG_0113.mp4 -c:v libvpx-vp9 -s 160x90 -b:v 25k -g 1 -tile-columns 4 -frame-parallel 1 -an -f webm -dash 1 video_160x90_25k.webm

ffmpeg -i IMG_0113.mp4 -c:v libvpx-vp9 -s 160x90 -b:v 50k -g 1 -tile-columns 4 -frame-parallel 1 -an -f webm -dash 1 video_160x90_50k.webm

ffmpeg -i IMG_0113.mp4 -vn -acodec libvorbis -ab 128k -dash 1 audio_128k.webm

ffmpeg -f webm_dash_manifest -i video_160x90_25k.webm -f webm_dash_manifest -i video_160x90_50k.webm -f webm_dash_manifest -i audio_128k.webm -c copy -map 0 -map 1 -map 2 -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1 id=1,streams=2" manifest.mpd




Secondly, the problem is not with my server, as I have downloaded the samples from here, and they work 100% on the dash.js player when served from my local server.



Please could someone out there point me in the right direction ? Or provide a sample of the ffmpeg commands used to get the output format correct.



Thanks,
Dean.

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">
