Description

Summary of the bug:

The current implementation of the MPEGTS muxer lacks the option for selecting the PCR interval time. The value used by default (at time) is quite small for some environments. So I request to add one option for setting this value.

Thank you!

Hi,

Current ffmpeg mpegts muxer uses a fixed PCR interval. But a fixed PCR interval isn't the best solution as...

  • DVB specifications: 40ms interval.
  • Generic MPEG specifications: 100ms interval.
  • ATSC specifications: 100-200ms interval.
  • IPTV streaming: <500ms max interval.

Please, provide an option for selecting an specific value.
Thank you!
