Devin Heitmueller 25d09ac0eb avdevice/decklink_enc: fix setting of last_pts to only be set for video 
The ff_decklink_write_packet() was always caching the last pts
received, to be used when calling StopScheduledPlayback(). However
because audio and video are on different timebases and the call to
StopScheduledPlayback() expects the video timebase, we'll end up
sending a weird value to the stop routine if the last packet
received contained audio.

Move the setting of last_pts to just be for the video stream.

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.
