Clément Bœsch 85452f9ab7 Merge commit 'e807491fc6a336e4becc0cbc981274a8fde18aba' 
* commit 'e807491fc6a336e4becc0cbc981274a8fde18aba':
  mpeg12dec: avoid signed overflow in bitrate calculation
  mpegvideo_parser: avoid signed overflow in bitrate calculation

This merge is a noop.

2017-04-29 12:54:15     @ubitux michaelni: is 740959fdbf enough to fix the overflow fixed in 58405de0951a843765625159402870c1eea3c3b1?
2017-04-29 12:55:53     @ubitux same question with e807491fc6
2017-04-29 13:21:45     michaelni       ubitux, the libav code refered to is wrong for us and i doubt the problem it fixes applies to us.
2017-04-29 13:24:29     @ubitux michaelni: ok, for both commits?
2017-04-29 13:33:55     michaelni       yes, they do more or less the same thing

  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
