Gaining Momentum

January 27th, 2009 by Multimedia Mike

Don’t look now, but the idea of making a formal FFmpeg release in the very near future is gaining traction over on the FFmpeg-devel list. There is a determined and growing team of individuals committed to this goal in the near future. To that end, there is even a Wiki page listing the steps that need to occur leading up to a release.

There is some debate about what kind of release schedule we should commit to. Some take the stance that we should follow the model that Wine apparently follows by releasing every 2 weeks. Really, every new weeks? I had never heard of that before. It strikes me as a bit severe. I personally would like to see a little more time between releases, but see them often enough that we get really good at it, and it becomes part of our shared community mindset.

After all, there are a few projects out there that depend on FFmpeg.

I admit, whenever I get to thinking about an FFmpeg release, I get a little nervous about the ensuing discussion. Not the discussion about whether or not a release should happen; that’s a foregone conclusion because it will happen. No, the item that makes me lose sleep is the biggest bikeshed hue discussion of them all — how should we version the upcoming release of FFmpeg? I don’t think I even want to get involved in that one.

Alpha FATE

January 25th, 2009 by Multimedia Mike

Do you remember the DEC Alpha CPU? Måns Rullgård does. He still has his unit in service and running Linux. So why not run FATE? Just like FFmpeg supports impossibly obscure multimedia formats, why shouldn’t it also support CPU types of approximately the same prevalence? In both cases, as long as the support overhead is not too arduous, it’s not a problem.

What I’m saying here, in case I was unclear, is that Måns has an Alpha CPU contributing build/test results to the central FATE database.

In other FATE news, today was a very busy day. I carefully evaluated and entered 18 new test specs:

With this, I have eliminated much of the low-hanging fruit on the FATE Test Coverage wiki page. My excuses to avoid testing the more complicated (read: bit inexact) formats are dwindling.

Meanwhile, the front page of FATE is reaching critical mass. I really need to come up with a new presentation because the front page is getting harder and harder to digest.

The FATE of PPC64

January 24th, 2009 by Multimedia Mike

Thanks to Reimar, Linux on 64-bit PowerPC is now a supported configuration in FATE.

Let’s keep the architectures coming.

Lossless Audio Tests

January 23rd, 2009 by Multimedia Mike

I feel a little more confident about the lossless audio decoders in FFmpeg — some of them, at least — so I activated the FATE tests that I had staged for them:

Further, I have added some tests related to Sierra game formats:
