Re: Thread Library Comparison (pthreads-win32, winpthreads, & w32threads)

This must be a mistake. But not yours, so thank you for clarifying. More work for me :(.

Re: Thread Library Comparison (pthreads-win32, winpthreads, & w32threads)

I don't see the issue in supporting DeckLink (in fact they endorse it) and the link you provide does not offer any information? Does this mean we have to make our own builds from now on?

Re: Thread Library Comparison (pthreads-win32, winpthreads, & w32threads)

Although I welcome experiments like these (just sorry I missed the announcement, is there a channel for this type of news?), it looks like ffmpeg is not ready for this as too much is now broken (including decklink support). So my vote is to go back to the old situation. Maybe a "beta" build with doc...

Re: Capturing from Decklink card broken after December 10 releases

Kyle, can you please officially confirm Decklink support has been cancelled? This is a major issue for me has I have recently rewritten my code to use ffmpeg for decklink output (not input) and, after a few hours of scratching my head, now see this thread explaining why my code broke. I would like t...

Re: Intel QSV Codecs

Thanks Kyle, although I quickly browse the revision lists I must have missed that (as well as your post). Just tried my last code and indeed it now sort of works, the error is indeed gone. But CPU usage is through the roof (and video is suddenly upside down, but that's not a problem). I'll have to r...

Re: Intel QSV Codecs

Anyone know if this is being handled? With all the pr Intel is giving ffmpeg, it seems like a waste to let this opportunity go by (and in fact reflect poorly on ffmpeg). The ticket seems dead.

Re: Intel QSV Codecs

It's odd this regression is not getting any attention, still not fixed: https://git.videolan.org/?p=ffmpeg.git; ... 1;hpb=n3.0

Re: Intel QSV Codecs

Don't know. i7-something. Frankly I did not even check if this particular PC supports quicksync as I assumed FFmpeg would give a nice warning (like it always does) that tells me in proper English that the CPU isn't supported. I have plenty of other PCs so could try it on various CPUs but I feel this...

Re: Intel QSV Codecs

I'm confused. I intentionally did not start investigating this exciting feature as I knew it was in beta. Now it is officially included in 3.0 I assumed it was tested. Defaults no longer working seems like a regression. I added the rate control and now I get the Error retrieving encoding parameters .

Re: Intel QSV Codecs

I did not try any of those things as both Intel and FFmpeg documentation and (recent) blogs always use these defaults, they never set any parameter. I find it hard to believe they just make these examples up without really testing them. See e.g. https://trac.ffmpeg.org/wiki/HWAccelIntro https://comm...
