From 2e266391559c2aa867c24593325f07effba97c64 Mon Sep 17 00:00:00 2001 From: wm4 Date: Thu, 5 Mar 2015 11:17:22 +0100 Subject: player, client API: refactor cplayer init, reduce client API differences Move the command line parsing and some other things to the common init routine shared between command line player and client API. This means they're using almost exactly the same code now. The main intended side effect is that the client API will load mpv.conf; though still only if config loading is enabled. (The cplayer still avoids creating an extra thread, passes a command line, and prints an exit status to the terminal. It also has some different defaults.) --- DOCS/client-api-changes.rst | 4 ++ libmpv/client.h | 8 ++-- player/client.c | 4 +- player/core.h | 2 +- player/main.c | 93 ++++++++++++++++++++++++--------------------- 5 files changed, 60 insertions(+), 51 deletions(-) diff --git a/DOCS/client-api-changes.rst b/DOCS/client-api-changes.rst index 842dd8500d..e375ae85ba 100644 --- a/DOCS/client-api-changes.rst +++ b/DOCS/client-api-changes.rst @@ -25,6 +25,10 @@ API changes :: + --- mpv 0.9.0 will be released --- + 1.15 - mpv_initialize() will now load config files.
