Getting a frame near the duration of the video returns null

[mebibou]

When using this code:

FFmpegMediaMetadataRetriever mmr = new FFmpegMediaMetadataRetriever();
mmr.setDataSource(videoFile);
Long duration = Long.parseLong(mmr.extractMetadata(FFmpegMediaMetadataRetriever.METADATA_KEY_DURATION));
Bitmap bitmap = mmr.getFrameAtTime(duration, FFmpegMediaMetadataRetriever.OPTION_CLOSEST);

I get a null bitmap. I've tried to remove a bit of buffer on the duration, and on my 5 seconds video I can only get a frame up to 4.5 seconds. 2 questions:

• is there a particular reason?
• would it be possible to just return the closest possible frame instead of returning null?

Did you find a solution?

No, i have to remove .5s on the duration to make sure I get something

@wseemann so that means you don't want to look at the issue?
