Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

  • fps = st->avg_frame_rate
  • tbr = st->r_frame_rate
  • tbn = st->time_base
  • tbc = st->codec->time_base

AVStream::avg_frame_rate

Average framerate.

  • demuxing: May be set by libavformat when creating the stream or in avformat_find_stream_info().
  • muxing: May be set by the caller before avformat_write_header().
