[gst-devel] Figure out performance with Gstreamer on ARM processor

[Vahe Gerald-B06319]

Hello List,

 

I am running FFMPEG codecs on an ARM processor.  In an attempt to figure
out performance, I am trying to encode the videotestsrc with the MPEG4
software encoder.

 

I initially pulled together this pipeline, which worked:

gst-launch -e videotestsrc ! video/x-raw-yuv, framerate=15/1, 
width=320, height=240 ! ffenc_mpeg4 ! avimux ! filesink
location=test.avi

 

 

However, I notice that the processor is over its limit.  In an attempt
to figure out how under real time it is, I figured I would create a RAW
file on the target with a known length.  (IE---10 seconds)

 

Then, ENCODE that file with a separate command.   That way, I could see
if it takes 12 seconds or 20 seconds to encode.  (And I will know how
close the processor is to handling it real time.)

 

To create the RAW file, I pulled together this pipeline, which appeared
to work fine:

gst-launch -e videotestsrc ! video/x-raw-yuv framerate=15/1, width=320,
height=240 ! filesink location=testraw.avi

 

 

Now, I was thinking I could use this command to "TIME" how long it would
take to encode the file.  However, I get a bunch of errors.  (Below)

 

time gst-launch -e filesrc location=testraw.avi ! ffenc_mpeg4 ! avimux !
filesink location=test.avi

 

Any Idea what I am doing wrong or what these errors mean?  I also tried
AVIMUX and DEMUX in their perspective places, but got similar errors.

 

Any Help or suggestions would be GREATLY appreciated!
