are you saying those times are the time to decode the frames or to decode and display the frames?

Hi,

 

We have observed that on Windows, ffmpeg is capable of extracting frames at 30 fps, using command line, using Xuggler, and using FFMPEG APIs directly in our code.

 

But when we move this implementation to Android, we are getting following results:

 

- 720p video (1280 x 720) - 16 fps (approx. 60 ms/frame)

- 1080p video (1920 x 1080) - 7 fps (approx. 140 ms/frame)

 

Video is recorded from Android Camera and it’s length is approx. 20-30 seconds. [Android Processor: “Quad-core 1.2 GHz Cortex-A7” and “Memory: 1GB”]

 

1.       How can we get 30 fps on Android?

2.       Are there any performance benchmarks for Android?

Hi Amber, 

In your previous post (Stackexchange)  you mention that your test was made on different plateform and you never test with CLI on the Android plateform, so can't compare results obtained on a computer, and on a phone. you would maybe try on your android palteform with another binary.
