Martin Storsjö 8f5de34c8f vf_fade: Make sure to not miss the last lines of a frame 
When slice_h is rounded up due to chroma subsampling, there's
a risk that jobnr * slice_h exceeds frame->height.

Prior to a638e9184d, this wasn't an issue for the last slice
of a frame, since slice_end was set to frame->height for the last
slice.

a638e9184d tried to fix the case where other slices than the
last one would exceed frame->height (which can happen where the
number of slices/threads is very large compared to the frame
height).

However, the fix in a638e9184d instead broke other cases,
where slice_h * nb_threads < frame->height. Therefore, make
sure the last slice always ends at frame->height.

Libav

Build Status

Libav is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libavresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • avconv is a command line toolbox to manipulate, convert and stream multimedia content.
  • avplay is a minimalistic multimedia player.
  • avprobe is a simple analisys tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
