RFC: libav vs. ffmpeg, redux

[Paul Eggleton]

Hi all,

A few years ago we made the switch from ffmpeg to libav (a mostly drop-in 
compatible fork), with fairly good justification at the time. However, it looks 
like Debian has just made the switch back to ffmpeg, citing a number of reasons 
- most notably more responsive security issue patching in recent history. 
Here's a page with their full reasoning:

  https://wiki.debian.org/Debate/libav-provider/ffmpeg

Gstreamer (gst-libav, specifically) has also just recently made the switch back 
for its internal copy:

  https://bugzilla.gnome.org/show_bug.cgi?id=751607

What do people think? Should we be looking to make the switch back in OE as 
well?

Cheers,
Paul

I say we switch back to ffmpeg, and do it as soon as possible so we're not
making this change during M3.

I totally endorse having a layer that has the one that isn't in oe-core,
but oe-core should pick one and support it properly.

That make sense to me. Also libav has LICENSE_FLAGS = "commercial" so 
the change which will simplify things too.

Why isn't that the case for ffmpeg too?

it remains same, commercial is for the folks who ship the code to be
aware that there might be algorithms implemented in the code
which are governed by patents, so if you start making money on that
code then they might want a share of it. So you have to have agreement
with patent folks as ffmpeg code is not available under commercial
license.

As much as I like the libav guys, ffmpeg seems to win the popular vote which
makes it easier to use. Kodi/xbmc has been named, opencv is another.
