ISDB向けmpv

追加・変更された機能

• デスクランブルしながらの再生
• DVBデバイスからの再生
  • ISDB-S/T用のチャンネル設定パラメータに対応
• デュアルモノ音声対応
  • 主音声のデフォルト再生
  • 言語指定による自動選択
  • ユーザによる選択・切り替え
• TSストリーム内での番組切り替わり(次番組開始)対応
  • 番組の切り替わり時点で終了していたのを再生継続するように
• 複数プログラム、複数トラック(映像・音声・字幕)が存在する際のトラック選択の改良
  • 番組(SID)の指定オプション
  • デフォルトフラグ、言語、所属プログラムを考慮したトラック自動選択

なお本修正はLinuxにのみ対応する。

本ブランチisdb-0.36での主な変更点

• 本家mpvのmasterブランチのv0.36.0タグにリベース
• 字幕表示機能は、本家側がffmpeg/libaribcaptionに対応したので、そちらを利用することとし、 従来からの(ASS拡張による)独自実装は削除した。
• 上記変更に伴い、パッチが必要な依存ライブラリもISDB向けffmpegだけとなった
• (ISDB向けパッチも最新版にリベース. ffmpeg:6.1)

追加で必要となる依存ライブラリ

• ISDB向けffmpeg (ほぼ必須)
• BCAS復号化ライブラリ:
  • デスクランブルしていないTSファイルの再生や、DVBデバイスからの再生をしたい場合に必要
  • libdemulti2: ベースのTSパケット復号ライブラリ +
    そこから呼び出すECM復号化ライブラリ(いずれか一つ)
    • libpcsclite: PC/SCでBCASカードを使用する場合
    • libsobacas: ソフトウェアでのカードシミュレーション。 libpcsclite互換I/F
    • libyakisoba: ソフトウェアECM復号機能のみのライブラリ
  • libpcsclite以外の入手はt●r板のDTV関連@T●r/1-100やFNの_jp_2ch_dtvを探すか、 ヘッダファイルを元に自作;)
• iconvモジュールgconv-module-aribb24:
  • TS内のメタ情報を文字化けなく利用したい場合に必要
    (現状ではチャンネル名がウインドウタイトルに表示されるのみ)

ビルド方法

0. BCAS復号化ライブラリのビルド・インストール(オプション)

libdemulti2に加え、{libpcsclite|libsobacas|libyakisoba}のいずれかをインストール

1. ISDB用iconvモジュールのビルド・インストール(オプション)

cd <somewhere>
git clone [--depth 1] https://github.com/0p1pp1/gconv-module-aribb24
cd gconv-module-aribb24 ; ./autogen.sh
mkdir build; cd build
../configure
make
sudo make install
echo 'export GCONV_PATH=/usr/local/lib/gconv/aribb24' | \
    sudo tee /etc/profile.d/gconv-module-aribb24.sh

2. libaribcaptionのビルド・インストール

本家 参照。(字幕表示機能が必要な場合のみ)

3. ISDB向けffmpegのビルド・インストール

一応オプションであるが、ほぼ必要。下記の例のようにffmpegが外部ライブラリでサポートしている コーデック/機能を使用したい場合は、事前に該当ライブラリをインストールしておく必要あり。

cd <somewhere>
git clone [--depth 1] -b isdb-6.1 https://github.com/0p1pp1/ffmpeg
cd ffmpeg
mkdir build; cd build
# 上記2.でlibaribcaptionを/usr/local/libにインストールしたなら
# export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
../configure --disable-doc --enable-gpl --enable-nonfree --enable-libass \
  --enable-gnutls --enable-libbluray --enable-libaom --enable-libdav1d \
  --enable-libmp3lame --enable-libtwolame --enable-libpulse \
  --enable-libtheora --enable-libopus --enable-libvorbis --enable-libvpx \
  --enable-libx264 --enable-libx265 --enable-libiec61883 --enable-libxml2  \
  --enable-opengl --enable-libdrm --enable-libaribcaption # --enable-libdemulti2
make
sudo make install
# すでに実行していなければ...
# echo '/usr/local/lib' | sudo tee /etc/ld.so.conf.d/local.conf
sudo ldconfig

4. mpvのビルド

cd <somewhere>
git clone [--depth 1] -b isdb-0.36 https://github.com/0p1pp1/mpv
cd mpv
meson setup --pkg-config-path /usr/local/lib/pkgconfig -D dvbin=enabled build
meson compile -C build

インストール・実行

meson install -C buildで/usr/local/binにインストールしてmpvで実行するか、
インストールせずに直接./build/mpv ...で実行する。

ISDB独自機能関連のUI

• コマンドラインでのDVBチャンネル指定: mpv dvb://[カード番号@]チャンネル名
  • チャンネル設定ファイル$XDG_CONFIG_HOME/mpv/channels.confが必要。
    • ISDB向けmplayerと同じ1行1チャンネルの形式
    • 地デジ向けはchannels.conf.isdbt, 衛星向けはchannels.conf.isdbsに分けて指定も可能
    • 上記デフォルト名以外のチャンネル設定ファイルは--dvbin-file=オプションで指定可
    • dvbアプリ集のs2scanコマンドで自動生成可能
  • dvb//1@NHK?frontend=1&demux=1&dvr=1のようなオプション指定も一応可能
  • デフォルトの設定だと再生開始まで時間がかかるので、 --demuxer-lavf-probesize=2000000のようにオプションを指定するか、 $XDG_CONFIG_HOME/mpv/mpv.confにDVBの自動プロファイルとして指定すると良い。

hwdec=auto

[protocol.dvb]
profile-desc="profile for dvb:// streams"
demuxer-lavf-probesize=2000000
demuxer-lavf-analyzeduration=1.3

• 字幕のオン・オフ/切り替え: 'j'キー(cycle subコマンド)
  • 複数言語字幕の場合も'j'キーでオフ->日本語字幕->英語字幕->オフのように切り替わる（はず）
• --slang=jpnコマンドラインオプションで、日本語字幕が有る時は自動的に表示
• デュアルモノラル音声の場合の主・副・両方の指定/切り替え：
  • --dmono={auto|main|sub|both}コマンドラインオプションで指定
  • dmono-modeプロパティへの設定で切り替え。input.confにA cycle dmono-mode等
  • 一般の音声切り替えコマンド(cycle audio,'#'キー)でも主->副->次の音声トラックに切り替え
• 再生するプログラムIDの明示指定:
  • --progid=<SID>コマンドラインオプション
  • programプロパティへの設定。(従来と同じ。 input.conf等で設定・切り替え)

キーバインディング/利用可能コマンドについてはetc/input.confやmpv(1)を参照。 $XDG_CONFIG_HOME/mpv/input.confでカスタマイズできる。

Overview

mpv is a free (as in freedom) media player for the command line. It supports a wide variety of media file formats, audio and video codecs, and subtitle types.

There is a FAQ.

Releases can be found on the release list.

System requirements

• A not too ancient Linux, Windows 7 or later, or OSX 10.8 or later.
• A somewhat capable CPU. Hardware decoding might help if the CPU is too slow to decode video in realtime, but must be explicitly enabled with the --hwdec option.
• A not too crappy GPU. mpv's focus is not on power-efficient playback on embedded or integrated GPUs (for example, hardware decoding is not even enabled by default). Low power GPUs may cause issues like tearing, stutter, etc. The main video output uses shaders for video rendering and scaling, rather than GPU fixed function hardware. On Windows, you might want to make sure the graphics drivers are current. In some cases, ancient fallback video output methods can help (such as --vo=xv on Linux), but this use is not recommended or supported.

Downloads

For semi-official builds and third-party packages please see mpv.io/installation.

Changelog

There is no complete changelog; however, changes to the player core interface are listed in the interface changelog.

Changes to the C API are documented in the client API changelog.

The release list has a summary of most of the important changes on every release.

Changes to the default key bindings are indicated in restore-old-bindings.conf.

Compilation

Compiling with full features requires development files for several external libraries. One of the two build systems supported by mpv is required: meson or waf. Meson can be obtained from your distro or PyPI. Waf can be downloaded by using the ./bootstrap.py script. It will get the latest version of waf that was tested with mpv. Some documentation about the differences between the build systems are located in build-system-differences.

Note: Building with waf is considered deprecated and will be removed in the future.

Meson

After creating your build directory (e.g. meson setup build), you can view a list of all the build options via meson configure build. You could also just simply look at the meson_options.txt file. Logs are stored in meson-logs within your build directory.

Example:

meson setup build
meson compile -C build
meson install -C build

Waf

For a list of the available build options use ./waf configure --help. If you think you have support for some feature installed but configure fails to detect it, the file build/config.log may contain information about the reasons for the failure.

NOTE: To avoid cluttering the output with unreadable spam, --help only shows one of the two switches for each option. If the option is autodetected or enabled by default, the --disable-*** switch is printed; if the option is disabled by default, the --enable-*** switch is printed. Either way, you can use --enable-*** or --disable-** regardless of what is printed by --help.

To build the software you can use ./waf build: the result of the compilation will be located in build/mpv. You can use ./waf install to install mpv to the prefix after it is compiled.

Example:

./bootstrap.py
./waf configure
./waf
./waf install

Essential dependencies (incomplete list):

• gcc or clang
• X development headers (xlib, xrandr, xext, xscrnsaver, xinerama, libvdpau, libGL, GLX, EGL, xv, ...)
• Audio output development headers (libasound/ALSA, pulseaudio)
• FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample)
• zlib
• iconv (normally provided by the system libc)
• libass (OSD, OSC, text subtitles)
• Lua (optional, required for the OSC pseudo-GUI and youtube-dl integration)
• libjpeg (optional, used for screenshots only)
• uchardet (optional, for subtitle charset detection)
• nvdec and vaapi libraries for hardware decoding on Linux (optional)

Libass dependencies (when building libass):

• gcc or clang, yasm on x86 and x86_64
• fribidi, freetype, fontconfig development headers (for libass)
• harfbuzz (required for correct rendering of combining characters, particularly for correct rendering of non-English text on OSX, and Arabic/Indic scripts on any platform)

FFmpeg dependencies (when building FFmpeg):

• gcc or clang, yasm on x86 and x86_64
• OpenSSL or GnuTLS (have to be explicitly enabled when compiling FFmpeg)
• libx264/libmp3lame/libfdk-aac if you want to use encoding (have to be explicitly enabled when compiling FFmpeg)
• For native DASH playback, FFmpeg needs to be built with --enable-libxml2 (although there are security implications, and DASH support has lots of bugs).
• AV1 decoding support requires dav1d.
• For good nvidia support on Linux, make sure nv-codec-headers is installed and can be found by configure.

Most of the above libraries are available in suitable versions on normal Linux distributions. For ease of compiling the latest git master of everything, you may wish to use the separately available build wrapper (mpv-build) which first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.

If you want to build a Windows binary, you either have to use MSYS2 and MinGW, or cross-compile from Linux with MinGW. See Windows compilation.

Release cycle

Every other month, an arbitrary git snapshot is made, and is assigned a 0.X.0 version number. No further maintenance is done.

The goal of releases is to make Linux distributions happy. Linux distributions are also expected to apply their own patches in case of bugs and security issues.

Releases other than the latest release are unsupported and unmaintained.

See the release policy document for more information.

Bug reports

Please use the issue tracker provided by GitHub to send us bug reports or feature requests. Follow the template's instructions or the issue will likely be ignored or closed as invalid.

Using the bug tracker as place for simple questions is fine but IRC is recommended (see Contact below).

Contributing

Please read contribute.md.

For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.

You can check the wiki or the issue tracker for ideas on what you could contribute with.

License

GPLv2 "or later" by default, LGPLv2.1 "or later" with --enable-lgpl. See details.

History

This software is based on the MPlayer project. Before mpv existed as a project, the code base was briefly developed under the mplayer2 project. For details, see the FAQ.
