can you provide some more information? What was the command that was being run? :-)

Yixi and Tongfang also encountered the same problem.

skyebend commented 10 years ago

Ok, this is the example off the saveVideo help page, right? It works for me. Do you see output from ffmepg on the R console? I wonder if it is some issue with the path to ffmpeg? Usually on windows I have to edit the system Path to put ffmpeg on it. Or it seems you can set the path via ani.oopts as in the example. What do you get with

Sys.which('ffmpeg')

Hi Skye, this is the example off the saveVideo help page, right? Yes

> Sys.which('ffmpeg')
                               ffmpeg 
"C:\\Rtools\\ffmpeg\\bin\\ffmpeg.exe"

I can see the animation from R console, and I do find the batch of png files at

C:\Users\kecoli\AppData\Local\Temp\RtmpsXOO9X/Rplot%d.png

The output of the code:

Video has been created at: C:\Users\kecoli\Documents\ndtv-shiny\BM.mp4
animation option 'nmax' changed: 300 --> 50

I can find the BM.mp4 at local path, and I committed it in ndtv-shiny respository as well. https://github.com/Statnet-Summer-Project/ndtv-shiny/blob/master/BM.mp4

skyebend commented 10 years ago

OK, so it it generating the movie, but there are problems with the video format.

noticed this in the ffmpeg output:

No pixel format specified, yuv444p for H.264 encoding chosen. Use -pix_fmt yuv420p for compatibility with outdated media players.

which makes me think it might be a variant of the ffmpeg pixel format bug https://statnet.csde.washington.edu/trac/ticket/711

Maybe adding

other.opts='-pix_fmt yuv420p"

to saveVideo() will work around the problem?

I opened a ticket for this with the animation library author: https://github.com/yihui/animation/issues/49

kecoli commented 10 years ago

Yep,

Adding

other.opts='-pix_fmt yuv420p"

works !

I should have noticed this from the output

Thanks Skye.

Best

skyebend commented 10 years ago

maybe if you add a 'me too' comment on https://github.com/yihui/animation/issues/49 saying that the example for saveVideo() gives black output they may be able to come up with a solution.

TongfangInCafe commented 10 years ago

Thank you very much, Kirk and Skye!
