Add a new muxer option mpegts_pcr_pid that generates PCR on a dedicated adaptation-field-only PID, separate from any elementary stream. ISDB-T 1seg receivers require PCR on a standalone PID. When PCR shares the video PID, these receivers acquire the service but refuse to decode video and audio. This is standard practice in Japanese digital terrestrial broadcasting per ARIB TR-B14. When mpegts_pcr_pid is set to a valid PID value: - PCR packets are generated as adaptation-field-only packets on the specified PID at the interval set by pcr_period - The video stream adaptation fields do not carry PCR flags - The PMT PCR_PID field is set to the specified PID When mpegts_pcr_pid is -1 (default): existing behavior is unchanged. The existing mpegts_insert_pcr_only function is refactored into a parameterized mpegts_insert_pcr_only_pid(s, pid, cc, discontinuity) to avoid code duplication.

FFmpeg README
FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodecprovides implementation of a wider range of codecs.libavformatimplements streaming protocols, container formats and basic I/O access.libavutilincludes hashers, decompressors and miscellaneous utility functions.libavfilterprovides means to alter decoded audio and video through a directed graph of connected filters.libavdeviceprovides an abstraction to access capture and playback devices.libswresampleimplements audio mixing and resampling routines.libswscaleimplements 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,ismindexandqt-faststart.
