Project IINA Support

[jurplel]

I'm seeing Mac development on the horizon, and this is my favorite player for Mac. I figured since it was MPV based, it would be easy to support.

Just a preliminary question, do you know if it is possible to control IINA via terminal, as for mpv? I installed it on my system via cask, but did not find any CLI for it.

[jurplel]

I'm not actually sure, but I found some relevant issues that might help answer your question.
iina/iina#875
iina/iina#58
streamlink/streamlink-twitch-gui#480
Looking like that's a no but in progress
iina/iina#898

[albertosottile]

Yep, according to the roadmap it has to be implemented yet. I am afraid that until they do that, we have no way to interact with IINA and add support for Syncplay. I guess we just have to wait and then try to adjust our mpv module accordingly.

I don't suppose any of these pages would be useful?

I already read those, as far as I understood there is no way to control the player status after IINA is launched from the command line...

[jurplel]

Okay, thanks for your time.

[albertosottile]

Thank you, maybe you could comment again when they release a functional CLI for IINA.

If it doesn't support terminal (which is what Syncplay currently uses for mpv) does it at least support the mpv JSON IPC protocol ?

[albertosottile]

From here: https://github.com/lhc70000/iina/wiki/Use-SVP-with-IINA it seems that it does, by adding an option in IINA's preferences. I just tried it and obtained a reasonable answer:
echo '{ "command": ["get_property", "playback-time"] }' | socat - /tmp/mpvsocket {"data":499.749000,"error":"success"}

So it should be possible to control IINA with this JSON IPC interface. Unfortunately, the effort required would be much higher than just adjusting the code in mpv.py .

Maybe we could ask @Hamuko to help, it seems that his Sopu client uses JSON IPC to control mpv (https://github.com/Hamuko/Sopu/blob/master/sopu/mediaplayer.py)

I don't use OSX so it'd definitely need someone to take it up not just to port it over but also to maintain it.

CLI is on the way it seems
iina/iina#1181

[albertosottile]

Great, let's wait for a release. In the meantime, @etoh do we use any --no-* option in mpv.py?

@jeep70 Great news! 👍

@alby128 We use "no-osd set" to set properties without affecting the OSD, but we don't make use of any command line options which start with --no. Depending on your definition, you could say --input-terminal=no (which we use in Syncplay) is equivalent to --no-input-terminal, but if the problem comes from using the --no prefix style to set variables then that doesn't happen (unless someone manually sets up a --no command in Syncplay player arguments).

On Windows, the default command line options are: ['--force-window', '--idle', '--hr-seek=always', '--keep-open', '--msg-level=all=error,cplayer=info,term-msg=info', '--input-terminal=no', '--input-file=/dev/stdin', '--term-playing-msg=<SyncplayUpdateFile>\nANS_filename=${filename}\nANS_length=${=length:${=duration:0}}\nANS_path=${path}\n</SyncplayUpdateFile>', '--terminal=yes']

iina/iina#1181 seems to have been merged into the develop branch. Is the IINA develop branch working properly with Syncplay @jeep70 (assuming you change the Syncplay code to detect IINA as mpv)?
