<p class=MsoNormal>Hello List,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>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.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I initially pulled together this pipeline, which worked:<o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'>gst-launch -e videotestsrc ! video/x-raw-yuv, framerate=15/1, <br>
width=320, height=240 ! ffenc_mpeg4 ! avimux ! filesink location=test.avi<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'>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)<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'>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.)<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal>To create the RAW file, I pulled together this pipeline,
which appeared to work fine:<o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'>gst-launch -e videotestsrc ! video/x-raw-yuv framerate=15/1,
width=320, height=240 ! filesink location=testraw.avi<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";
color:black'><o:p> </o:p></span></p>
<p class=MsoNormal>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)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";

also tried AVIMUX and DEMUX in their perspective places, but got similar
errors.<o:p></o:p></span></p>
