Help with decode

[kmathew]

I use cef for a project (CEF 4103 in Ubuntu 16.04) and AAC decode is disabled with a chromium patch. I need help in using the system gstreamer apis to do AAC decode. Since FFMPEG is used internally, how can I use gstreamer aac decode alone in this context (without having to completely replace FFMPEG). Any help is appreciated.

Proprietary codecs are disabled in Chromium by default. However, you can build Chromium with these codecs enabled. See for example viewtopic.php?f=6&t=13515&start=40#p35221

Thanks for the pointers. In case I need to continue disable the proprietary codecs. Let's say in the case of AAC codec, I want it to be disabled in chromium build and want to use gstreamer for purpose of decode. Are there any pointers to that.

That will be a substantial amount of work. You will need to figure out how to use gstreamer instead of ffmpeg in Chromium. I have no pointers for that.

Thanks for the reply. I don't want to replace the comple ffmpeg with gstreamer. Keeping the ffmpeg pipeline and only switch to gstreamer if AAC decode is required. Video decode and even the whole pipeline should use the default ffmpeg pipeline if AAC decode is not required. Not sure if this would be more difficult.
