A more detailed commit message would be good. How does this differ from
gst-ffmpeg? I see you depend on ffmpeg and not libav (which we currently
don't have in BR).

 To be honest, I find it redundant to repeat the help text of Config.in in
the commit message when adding a new package.  When you look at the project
history, you will probably already have looked at the package's files first.

 Regards,
 Arnout

 That said, an explanation why it depends on ffmpeg instead of libav would be
good.  But then in the mk-file, not in the commit message.

 Arnout

I thought the help text explained that: gst-ffmpeg disables certain
codecs, like MP3, Vorbis, Theora, etc. IOW. It has political baggage
from GStreamer developers; they don't want people to use FFmpeg, they
want people to use native elements: vorbisdec, theoradec, maddec, etc.

And gst-av works for both libav, and FFmpeg. Obviously, I wrote it for
libav, but FFmpeg is simply an old version of the same API.

Cheers.

But how does (more-or-less) reimplementing gst-ffmpeg change this
political baggage?

I don't have to convince GStreamer developers--I know many of them,
and I doubt they would allow such a change.

Plus, here's another important part of the description[1]:

---
In addition, it is much simpler (2654 vs 16575 LOC), has better
performance, and has a bit of extra features (such as less latency),
and doesn?t use deprecated API?s. In a previous post I measured
exactly how much improvement compared to gst-ffmpeg there is; it?s not
much, but it?s some.
---

Yes, I have actually measured the power usage[2].

But the main reason is the complexity of the code. If you quickly skim
through both code-bases, you would see what I mean :)

Cheers.

Ok, I get it now - Thanks.
