playVideo and Sound Content?

[Kydoimos 916]

Hi all - can anyone tell me why I have a 2-3 second sound delay when I use the playVideo function? The sound is correct on the .OGV format video.

[mrchy 2]

try like this

sleep 0.1;

_video = ["rsc\tunel.ogg"] spawn bis_fnc_playVideo;

waitUntil {scriptDone _video};

2 cutText ["", "BLACK IN"];

};

[Kydoimos 916]

Still out of sync, I'm afraid.

[mrchy 2]

you need to convert again the video and check also the fps of the original video or use another program for convert video

[Kydoimos 916]

Original video is DivX HD, 1920 x 1080

12000kbit/s, 29.97 frames/sec

AAC, 16 it stereo, 48kHz

I'm converting at:

i use vlc player isnt the best but its work correctly

[Kydoimos 916]

I've got VLC, I'll try that now - seems to be only recording the audio for the OGG (video)...

Thanks though, MrChy, you've been very helpful! ;-p

[Kydoimos 916]

I'm really struggling with this - can anyone offer to convert my file? I need a lossless conversion on an HD .mkv to OGG which will play correctly on A3... if there's anyone out there... please! You'd be a hero! I've tried VLC and some online converters but have had no success.

Just an out of the blue guess, is the video/audio converted with constant bitrate? variable bitrate can sometimes lead to sync issues

[mcpxxl 2]

I have also tried a lot but no success

The used AAN BIS video does not have syncron sound and pic sequences so no one will see the gap between

[Kydoimos 916]

I'm implementing a workaround, which involves shifting the audio about! It's barbaric but it ought to do the job!

[Kydoimos 916]

Ok - so I've tried several different converters, and with several different start formats - out of sync with each! Really can't think why this is happening?!

[Magirot 14]

Same problem here, no idea of the cause. It's not very comfortable how often the game crashes when trying out different solutions, apparently in reaction to wrong aspect ratio.

A similar crude workaround I could think of was to play the audio seperately with playSound, and it seems to work reasonably well. You might want to give it a try to see if it works with longer videos. Here's an example mission with both versions, and choices in the action menu if you preview it: videotest.Stratis.zip (4,3mb)

I wish we got a surefire way to get it working straight from the .ogv.

[Kydoimos 916]

Thanks Magirot - perhaps we should address this on the feedback tracker? OGV seem bug-ridden!

[Kydoimos 916]

£10 via payPal to the first one who can help me get a HD quality OGV video working with audio and video in sync!

£15 via payPal... I'm upping the stakes.

[mrchy 2]

Up for 100£ ? ;)

the problem i think, its because you try to convert video coded in dvix, try to convert it first in avi and after that you can use vlc or whatever you want for convert it. also try to check the format audio and get the general format audio

I did try to convert a raw video with both VLC and ffmpeg2theora. With the latter I also tested different setups I could dig up with google, all had either the same old desync or even worse problems.

Has someone actually got it working correctly? None of the older threads I find on the subject mention this stuff.

[mrchy 2]

ok im just curious, can you send me a link where i can download the video and i will convert it for you, i made since 2 weeks many video in ogg /ogv and i dont have any trouble with sound.

[Magirot 14]

Have you used them in-game? I don't have any trouble with sound while playing them with regular media players either, but in Arma 3 there's always the desync.

[Kydoimos 916]

Here's a link to my video: https://www.dropbox.com/s/mexrqehwlgghcww/Video.zip - I need to get a lossless HD copy in an OGV that works! If anyone susses it out I'll owe you big time!

[mrchy 2]

Back, i just convert it on the fly, and i just realize your video its from a great project ;)

so, there is something wrong with your video, 2 minutes in [MP4] 154 mega........... "the force is strong with you" ;)

First : i don't know if arma can handle video for 2 min maybe yes i dont know, i always make video around 6 to 10 sec but its for MP

Second : what kind of program did you use for make the video ?

third : i converted with my regular parameter for ogg, and its seems the video don't have constant quality also i get a big audio desync at the end of the video

Maybe you can make a combination of *PAA file for your intro, or i just thinking if the trouble come from the 2 minutes, you can cut your video in 4 or 3, its can be a solution against desync.

sorry mate, vlc get hard time to convert your video and he did it not well 75 mega final result and not stable quality.

[Magirot 14]

I don't think it's related to length, since at least with me the audio always desyncs in the first few seconds regardless of how long it is. I've tried clips ranging from 4 seconds to ~5 minutes.

Still there must be a working encoding setup, since BI's own intro works fine if you call it in your own mission, and apparently you've gotten shorter videos to work as well? I played around with Kydoimos' file in ffmpeg2theora (since that's what BI used), and I actually got the sync to be better than what it usually is for me, but there's still an annoying sound failure in the beginning, and it's clearly not as good as with a regular media player.

On another note, if there are other people like me who hadn't checked BI's own scripts before, here's initIntro.sqf from Survive with the subtitles removed. Makes the mission intro consist of only the video in an apparently performance friendly manner and then ends the intro section.

0 fadeSound 0;
titleCut ["", "BLACK FADED", 10e10];

[] spawn {
waitUntil {time > 0};
enableEnvironment false;
};

// Limit view distance
setViewDistance 500;

// Create upwards-facing camera
private ["_camera"];
_camera = "Camera" camCreate [10,10,10];
_camera cameraEffect ["INTERNAL", "BACK"];

_camera camPreparePos [10,10,10];
_camera camPrepareTarget [10,10,1000];
_camera camPrepareFOV 0.7;
_camera camCommitPrepared 0;

sleep 1;

private ["_video"];
_video = ["A3\Missions_F_EPA\video\A_in_intro.ogv"] spawn BIS_fnc_playVideo;

waitUntil {scriptDone _video};

sleep 1;

_camera cameraEffect ["TERMINATE", "BACK"];
camDestroy _camera;

// Terminate intro
endMission "END1";

[Kydoimos 916]

Yeah - certainly not related to length - good thinking though! Chances are, it might be something like that...

I used Pinnacle Studio 16 to make the video...
