movies not reaching thier end

in Core Library Questions • 4 months ago

Hi,
I don't get why this doesn't work

movie.play();
if(movie.time() == movie.duration()){
println("movie ended");
}

the problem is that using the play() method is supposed to stop at the last frame of the movie however the duration of the movie is never equal to the playback head's position when it's on the last frame. Eventhough both values are returned in seconds.
Instead what you get is something like this.

First, it's unclear which Processing version and thus video library you use, but if you are using 2.0b9, then perhaps you can file this as an issue on GitHub.

Second, you only need to call play() once in setup(), not over and over again.

Third, as a workaround you can store time in a variable previousTime and compare it with the current time. If they are equal (as you see at the end), then the movie has reached the end.

Hi,

I know that the play method only needs to be called once, i wasn't referring to the code not working or asking if there is anything wrong with that (as it's only a fragment) I was referring to the time as read from the playhead when it reaches the end of the movie not being equal to the length of the movie. please review the previous comment to note that these values are not equal at the end.

this is with processing 2.08b i don't recall seeing any updates to the movie class in the 2.09b changelog, but i'll give it a try and post back if it's different.

I know that the values are not equal at the end. That's why I suggested filing a bug report for the latest Processing version on GitHub and I provided a workaround that achieved that same goal but didn't rely on duration().
