[FFmpeg-devel] FFmpeg internal API: access to encoder private
options  Dmitry Samonenko shreddingwork at gmail.com Sat Oct 6
10:29:33 CEST 2012   Some of the FFmpeg encoders specify options
which can adjust it's operation slightly - most of the time
turning optional or legacy features on.  For example, libspeex
encoder supports several options turning on some of it's rich
features set. As far as I understand code, all options defined
for the encoder are parsed and stored in encoder context struct
- LibSpeexEncContext (for libspeexenc case), which,  on the
other hand, is the priv_data field of AVCodecContext struct.
So, is there a way using AVOption API (may I call it like that?)
to access these options?  I'm asking this because I'm working on
a patch for SDP with speex payload and RFC states that some of
the params must be present only when encoder is configured with
particular feature(-s). Function that does SDP populating is
issued with AVFormatContext and AVCodecContext. Please, correct
me if I am wrong,
