• How to deal ffplay bein too slow playing iPhone's videos ?

  21 janvier 2019, par Mikhail T.

  Trying to play a 3840x2160 video recorded by an iPhone 7 (@30fps), I get frequent pauses — in the video, music keeps playing.

  This happens both in firefox and when ffplay is invoked to play the file directly — from command-line. The CPU is a dual E6700 @3.20GHz — not super fast, but it should be able to play smoothly, shouldn’t it ? Video is Intel’s "series 4" integrated chipset — again, not a speed-daemon, but it should be adequate... Support for Intel’s VA API is included.

  I build ffmpeg-4.1 from source using FreeBSD port. As you can see, the port has a maddening amount of options — including several different ones for the 264-codec.

  Any suggestions for improving the decoding speed to the point, where it is watchable by a human ? Thank you !
