asilvestre 1c2dae153c avformat/flvenc: avoid 24bit timestamp truncation for FLV metadata 
FLV AMF tags have a 24bit field for timestamps plus an 8bit for extended
timestamps.

All FLV AMF tags except when we write metadata handle this correctly
using the put_timestamp function.

Until now when writing metadata we were only using the first
24 bits and thus the timestamp value was wraping around 4 hours 40
minutes (16,800,000 ms, max 24 bit value 16,777,216) of playback.

This commit fixes this applying this same function put_timestamp
for the metadata FLV tag.

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.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.
