I started working on NaCl recently and I was successful in applying few
post-processing effects to the audio and playing back onto the Chrome
Now, my requirement is to demux the audio from the video which is played
using HTML5 <video> tag and apply the effects to the audio and remux it
back and render it in the browser. I realized FFMPEG would help me to demux
and remux the raw video stream. And also I read somewhere that it has VA
API (Video Acceleration) that helps to render the remuxed video onto the
screen. I am little bit confused on this and looking to start on this
Here are my clear thoughts what I want.
- Able to demux audio from video and remux by applying few effects to
the audio stream, may be ffmpeg so I need one sample where I could do this.
- If so how can I apply this step to the video that is played using
HTML5 <video> tag. Is it possible if not do I have to start writing my own
HTML5 video player.
- How can I render the remuxed video and audio without any lags.
Any help is highly appreciable.
Is GStreamer can be another bet for me?
Thanks alot for your help.
