vp8_scalable_patterns

[Sujeevan Rajayogam]

Hi,

I'm trying to understand the output of the vp8_scalable_patterns example. I ran the example using the following command: vp8_scalable_patterns /tmp/test.flv /tmp/scalable_test 1280 720 1 30 0 10 20 30.  I see that files /tmp/scalable_test_[0-2].ivf are generated.  I'm assuming each of these files represent a different frame rate (10, 20 and 30).

Can you please explain the following:

1. What the output files are?

2. What are the dependencies between files?

2. How to decode the files?  I tried playing the .ivf files in vlc and they're garbled.  I also tried decoding them using vp8 decoder (decoded successfully) and then played in vlc and I still see garbled video.

Thanks,

Sujee
