A cast to int has gone wrong. Please contact the mp4parser discussion group (2332179761)

Hi, I got this error trying to combine MP4s that had just been recorded by the MediaRecorder.

This worked fine on my galaxy S5 (Android 6) and also on nexus 4 (Android 5.1),

But using phone Motorola X (XT1053) with Android 5.1 I get this exception every time. Any ideas what might be the issue?

Using latest version 1.1.21.

This happens when I try to parse a file > 2GB. The "cast to int" is the clue, if the file size is larger than what a signed 32-bit int can hold. Perhaps wherever this happens, should use long instead?

same issue with me but file size is less the 10 MB

I have found this issue in two phones Moto g5 plus and Moto z2 play, other devices are fine. The crash occurs in
Movie m = MovieCreator.build(video);
where video is the path to the video file in internal memory.

Hello,
I have exactly the same exception sometimes with short videos.
Do you have any solutions to this ?

[Lapinou42]

Well, for someone who have the same error (I'm on Xamarin Android but it's the same on Android):

I use the 1.1.8 version that seems to fix the Cast to int error.
Then, I check if a file exists at the same path used in the MovieCreator.build(path) and if it exists, I delete it.
This resolves the OOM exception.

I'm experiencing this error in a test trying to parse a container I just wrote. Here's my StackOverflow question and a public GitHub project I made specifically to reproduce this issue.

Is there a new update for this issue?

[febinmathew]

Any updates?
