James Almer cbcc817353 avcodec/vorbisdec: export skip_samples instead of dropping frames 
pts may not be set on input packets, which could result in the entire stream
being discarded.
This reverts commit 8fc2dedfe6, reintroducing the
behavior it replaced but now allowing the caller to manually drop the preroll
samples by looking at the skip_samples side data at the start while ignoring it
on seek, by setting the skip_manual avctx flag.

Fixes ticket #10251.

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.
