[FFmpeg-cvslog] ffprobe: add multiple_sections field to WriterContext

[Stefano Sabatini]

ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Sun May 27 00:59:28 2012 +0200| [fa6cb2fdffe59fdd38bf127ff82d09a4fcf46b76] | committer: Stefano Sabatini

ffprobe: add multiple_sections field to WriterContext

Move the field "multiple_entries" from the JSON writer private context to
WriterContext, and rename it "multiple_sections".

This allows to factorize the code with the pending INI format patch.
