[FFmpeg-devel] aac_latm: SSR is not implemented

I have a mpegts file with a HE-AAC audio track that cannot be decoded by
ffmpeg. I have uploaded a sample at the link below, as requested by the
decoder.

Happy to help with a patch to fix this issue, if someone can point me in
the right direction. FWIW, VLC is able to decode the audio without issue.
