QImage list to MP4

Well for the mentioned platform, there are installers available so it seem not huge
issue to bundle it. But I agree, there might be details with it.
https://ffmpeg.org/download.html

On the other hand, having the right libs for each platform and linking it will not be
super trivial either.

I would fool around with the samples
https://ffmpeg.org/doxygen/3.2/examples.html
and see how it felt before deciding which route would be best.

@mrjj
I'll try and report back here if I succeed (for further reference and other people which may experience the same issue)

Hi and welcome to devnet,

IIRC H.264 is a licensed codec so you have to take that into account.

Otherwise, it's completely doable to use ffmpeg with Qt.

H.264 is a licensed codec

Oh yep it is. Hrm. What should I do about that..

I guess contacting their licensing?

[SGaist]

AFAIK, yes, at least to know the conditions required to use the encoder.

Otherwise you have free formats like webm that you can use.

[ArsenArsen]

@SGaist I think I'll do that instead. I've been looking around and seems like getting licensed is a hellish process. I'll use WebM. Thanks for letting me know before I made the mistake :)

Turns out this is a lot easier than I first expected. Files are here. The link will soon be dead as I am merging that branch with master. Thanks for your support!

goto

[ArsenArsen]

@VRonin Seems like the best choice there honestly, because the .... and this can be done without it. I see now.

Meh. It works.

inb4 dead

@VRonin hey don't just goto to harshly, its still the best way to break out of nested loops...

...
Except mabye making the nested loop a function and using return....

bool breakAll=false;
for(int i=0;i<1000 && !breakAll;++i){
for(int j=0;j<1000 && !breakAll;++j){
if(shouldIStopEverything())
breakAll=true;
}
}

[ArsenArsen]

I wasn't wrong. The link is dead. New one

[VRonin]

We are going WAY off topic

bool Encoder::end() {
    if (success)
        av_write_trailer(fc);
    avcodec_free_context(&out->enc);
    av_frame_free(&out->frame);
    sws_freeContext(out->sws);
    delete out;
    if (!(fc->oformat->flags & AVFMT_NOFILE)) //
        avio_closep(&fc->pb);
    avformat_free_context(fc);
    return success;
}
