vulkan_decode: use coded_width/height instead of the non-coded width and height 
Partially fixes https://streams.videolan.org/issues/19938/20000_20180305-15.04.59.ts
The is coded as 1920x1080, meant to be rendered at 1440x1080 with cropping,
or 1680x1080 before cropping. Currently, the created DPB is 1440x1080, which results
in the image being decoded incorrectly, as the decoder overwrites output memory.
This commit fixes this.

FFmpeg README

FFmpeg 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 means to alter decoded audio and video through a directed graph of connected filters.
  • 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.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
