How to reencode a h264 wiiU to a standard format video
26 juin 2016, par didix16I’m trying to make a bridge between wiiU and web interface to view the video h264 signal. I’m not familiar with video programming but I’m searching some info about it. Following this documentation :
- http://libdrc.org/docs/re/sc-vstrm.html
- http://libdrc.org/docs/installation.html#patched-dependencies
It says that wiiU works with a H.264 variation. So since there is someone who made a h264decoder of wiiU in python (https: //github.com/justjake/drc-sim-keyboard/blob/master/H264Decoder.py) I’ll want to decode that kind of h264 and transform it to some kind of standard video for stream and get it over
<video></video>tag on a html5 web page. It is possibly do it with ffmpeg libraries ?If it, can someone tell me how ? I’m programming the bridge in C++.
Oh yes, at the moment I’m capturing the data from udp socket, so I just need transform the incoming data detailed in sc-vstrm.html documentation into some web stream video standard.
Thank you so much guys :).

"Widen" the stereo with Web Audio API
20 février 2018, par Dan P.I am trying to use the Web Audio API to match an ffmpeg command I run on the server to widen the stereo of a audio tracks.
With ffmpeg, I use : https://ffmpeg.org/ffmpeg-filters.html#stereowiden
More specifically, this my ffmpeg command :
stereowiden=delay=1:feedback=0.13:crossfeed=0:drymix=1In JS with the Web Audio API I’ve tried using the
StereoPanNode(https://developer.mozilla.org/en-US/docs/Web/API/StereoPannerNode) but this only seems to pan the audio left and right. I’ve also tried to combine it with theDelayNode(https://developer.mozilla.org/en-US/docs/Web/API/DelayNode), still in vain.How would you achieve that ?

What's the most performant way to encode an mp4 video of frames from a webgl canvas using Javascript in a web browser ?
17 janvier 2024, par Keith CarterI can capture the frames from the canvas using readPixels (https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/readPixels) but then what ?


I think there are a few wasm versions of ffmpeg but they're slow.


I found this web assembly mp4 encoder but it's no longer supported and doesn't work in Chrome on my phone (Android 13).


Any other suggestions ?
