各パッチの簡単な説明を記載しておきます。

■ ffmpeg-4.2-libavcodec-av-picture-structure.diff
----------------------------------------------------------------------------------------------------
[パッチ対象]
-> libavcodec/mpegvideo_parser.c
libavformat のパーサーで取得する情報に、MPEG-2 Videoのフィールド構造ピクチャーの情報を追加します。
フィールド構造ピクチャーにおけるフィールドオーダーの情報を正しく得る為に必要なパッチです。
※ デフォルトだとフィールド構造ピクチャーは強制的にBFFとして扱われてしまう

libavcodec/mpegvideo_parser: improve detection of progressive mpeg2
https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/88e2dc7d0448d1d4656c78454bc5f17063b867e7
https://github.com/FFmpeg/FFmpeg/commit/88e2dc7d0448d1d4656c78454bc5f17063b867e7
FFmpeg 4.x以降は、上記コミット(ffprobeでのMPEG-2 Videoプログレッシブフレーム検出)が適応された事で、
MPEG-2 VideoにおけるRFFを伴う2-3プルダウン処理対象となる24pフレームが有するフィールドオーダー情報が
取得できない状態になっています。
これにより、L-SMASH WorksではMPEG-2 Videoへリピート制御を適応できなくなる不具合が発生します。
本件に関して以下の変更を行う事で対策を図るパッチです。
(1) 上記コミットをリバート
(2) libavcodec にプログレッシブフレーム判定に必要なフラグを追加
(3) libavcodec と ffprobe にプログレッシブフレーム判定処理を追加
【備考】
ffprobe を初めて実行してみた程度の ffprobe 初心者なので、
・24pにRFF＆TFFフラグがセットされているデータに対して「progressive」とだけ表示した方が良いか？
・破損GOP部分を解析した場合に progressive_sequence が取得できない事で「progressive (bottom first)」
　となる(※補足参照)が、壊した人が求めている ffprobe での動作(表示)はコレで良いのか？
と言った点に関して、本パッチ内容の良し悪しを判断してかねています。
【補足】
尚、壊したコミットに記載されているサンプルデータ(720p.ts)はプログレッシブオンリーのデータですが、
MPEG-TSの先頭がGOP先頭フレームではないので先頭フレームを対象に解析が行われると progressive_sequence
の値を取得する事ができません。
その為、mpegvideo_parser 内ではインターレース用(=I/P混在)判定で処理が行われ、ffprobe 上で
「bottom frist」が表示されます。(本パッチを導入した場合は「progressive (bottom first)」)
このサンプルデータも、GOP先頭フレームがファイル先頭となる様にファイルカットを行えば、
問題のコミット反映前の ffprobe でも「progressive」と表示される様になります。
----------------------------------------------------------------------------------------------------
■ ffmpeg-4.2-libavcodec-temporal-reference.diff
----------------------------------------------------------------------------------------------------
[パッチ対象]
-> libavcodec/mpegvideo_parser.c
libavformat のパーサーで取得する情報に、MPEG-2 Videoのフレーム毎のGOP内参照順序の情報を追加します。
L-SMASH Worksのインデックスファイル(.lwi)にフレームの表示順序(POC)が記載されるようになりますが、
今のところ使用用途は有りません。
※ とある問題を解析・対処できないか検討するために追加したパッチ
※ 優先度が低いので検討自体を保留中
----------------------------------------------------------------------------------------------------
■ ffmpeg-4.2-libavformat-fix-update-wrap-reference.diff
----------------------------------------------------------------------------------------------------
[パッチ対象]
-> libavformat/utils.c
libavformat のラップアラウンド用タイムスタンプ補正処理を修正するパッチです。
番組切り替えを含んだ放送MPEG-TSにおいて、ストリーム構成が変更される(例：主音声⇒主＋副音声)場合に
FFmpegの持つラップアラウンド判定用情報が間違って更新される現象が発生する事を確認しました。
これによりストリーム構成の変更前後がラップアラウンド発生中と見されタイムスタンプ補正処理が間違って
適応されてしまい、フレームが正しい順序で表示されなくなる現象が発生します。
※ パッチ対象となるのはFFmpegのみ (Libavはラップアラウンド用タイムスタンプ補正処理が未搭載)
※ <2017/9/10 作成> 使用は各々の判断でお願いします

■ ffmpeg-3.4.1-allpatches+field-pic-r2.diff
----------------------------------------------------------------------------------------------------
3.4.x 用一括パッチ。
上記パッチにnekopanda氏のFFmpeg修正パッチ(MPEG-2 Video フィールド構造ピクチャーのデコーダー修正)
をまとめたパッチファイルです。一括適用したい場合に使用してください。

■ ffmpeg-3.4.1-libavcodec-av-picture-structure.diff
■ ffmpeg-3.4.1-libavformat-fix-update-wrap-reference.diff
----------------------------------------------------------------------------------------------------
外部参照されているこの2点のパッチは旧ファイル名の物を残しておきます。
尚、各パッチのファイル名を ffmpeg-4.2-～ に更新しましたが、変更内容自体は3.4.x 用と変わりありません。
