@ -195,19 +195,10 @@ Some notes on how ffmpeg wrapping inside GStreamer currently works:
* gstffmpeg{dec,enc,demux,mux}.c are wrappers for specific element types from
their ffmpeg counterpart. If you want to wrap a new type of element in
wrapper file.
* gstffmpegcolorspace.c is a wrapper for one specific function in ffmpeg:
colorspace conversion. This works different from the previously mentioned
ones, and we'll come to that in the next item. If you want to wrap one
specific function, then that, too, belongs in a new wrapper file.
* the important difference between all those is that the colorspace element
contains one element, so there is a 1<->1 mapping. This makes for a fairly
basic element implementation. gstffmpegcolorspace.c, therefore, doesn't
differ much from other colorspace elements. The ffmpeg element types,
however, define a whole *list* of elements (in GStreamer, each decoder etc.
needs to be its own element). We use a set of tricks for that to keep
coding simple: codec mapping and dynamic type creation.

We use a set of tricks for that to keep coding simple: codec

* ffmpeg uses CODEC_ID_* enumerations for their codecs. GStreamer uses caps,
which consists of a mimetype and a defined set of properties. In ffmpeg,
