Could not append initialization segment to source buffer about kino HOT 7 OPEN

@dero could you please provide Quân with a few examples of the commands you’re using to generate the manifests when you’re back online.

@derekherman I was following this tutorial to generate 3 different representations. I dont have much experience with video encoding so I just pretty much copied the script

Here's the link to the tutorial:

Here's the generated ffmpeg command for segmenting into chunks and generating manifest file:

ffmpeg -i D:\Hoc Tap\Project III\VideoStreaming\react-node-video-streaming\server\tmp\file_example_MP4_1920_18MG-
1639910101254\file_example_MP4_1920_18MG-1639910101255.mp4 -y -acodec aac -ac 2 -ar 44100 -vcodec libx264 -f dash 
-preset veryfast -keyint_min 60 -g 60 -sc_threshold 0 -profile:v main -use_template 1 -use_timeline 1 -b_strategy 0 -bf 1 -map 
0:a? -b:a 96k -filter_complex [0]format=pix_fmts=yuv420p[temp0];[temp0]scale=-2:240[A0] -map [A0]:v -b:v:0 350k 
-filter_complex [0]format=pix_fmts=yuv420p[temp1];[temp1]scale=-2:480[A1] -map [A1]:v -b:v:1 700k 
-filter_complex [0]format=pix_fmts=yuv420p[temp2];[temp2]scale=-2:720[A2] -map [A2]:v -b:v:2 2500k 
D:\Hoc Tap\Project III\VideoStreaming\react-node-video-streaming\server\tmp\file_example_MP4_1920_18MG-1639910101254\file_example_MP4_1920_18MG-1639910101255.mpd

I honestly don't understand most of the things inside the command and just managed to run and generate the segments and manifest which I thought would run. Maybe there's something wrong with this command ? I'd be best if you could share some sample commands to correctly generate the segments and manifest :D

@derekherman i'm really sorry if i keep asking for ffmpeg commands that you used but i really need them now to have a look since i'm doing a school project and the deadline is about to be due :( The streaming part is the core part of my project so I managed to set up everything but could not load chunk to the buffer. I'd very much appreciate it if you could provide (or ask s.o handling this part) some examples of the commands soon. Thank you for replying my issue!

@quanhoang288 The commands used to generate the sample videos are a part of the posts that explain streaming:

• https://kinoweb.dev/streaming-basics/
• https://kinoweb.dev/efficient-formats/

See the "Example FFmpeg command" section in both of those posts. Do those help?

@dero thanks a lot, i'll check it out and see if it works xD

@dero I'm sorry for bothering again but it didn't seem to work for me. I was able to encode the video but it throws this error when trying to load the initialization segment to the buffer:

When I use the media tool in Chrome it gives me this error:
Invalid top-level ISO BMFF box type 0xbfbd6d6f
Could you give me some insights on this ? Thank you

@derekherman could you help me take a look at the problem for a bit ? I reference kino generated manifests and they look similar to mine but somehow it still didnt work. Any insight would be appreciated
