Marton Balint 8dd5bb7280 avformat/mov: fix timecode with high frame rate content 
60 fps content have "Number of Frames" set to 30 in the tmcd atom, but the
frame duration / timescale reflects the original video frame rate.

Therefore we multiply the frame count with the quotient of the rounded timecode
frame rate and the "Number of Frames" per second to get a frame count in the original
(higher) frame rate.

Note that the frames part in the timecode will be in high frame rate which will
make the timecode different to e.g. MediaInfo which seems to show the 30 fps
timecode even for 120 fps content.

Regression since 428b4aacb1.

Fixes ticket #9710.
Fixes ticket #9492.

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.
