[gst-devel] Encoding RAW file on Arm to test performance

[gv]

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 over 100% utilization (Not surprising,
since I am doing in software).  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) and 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.  (At Bottom of
post)

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


UPDATE!!!! 
I did add the videoparse before the ffenc_mpeg4.  This DID encode the file,
and didnt create any errors, but the video looks incorrect.  Almost as if
there is a mismatch between the formats.


Any Help or suggestions would be GREATLY appreciated!
