videotestsrc
ARM load: 157% but only videotestsrc consumes 100%. According to the NVIDIA forum when using videotestsrc the system is also doing memory copies to feed the encoder with NVMM memory buffers so that loads more the ARM.
gst-launch-1.0 videotestsrc num-buffers=150 ! 'video/x-raw, format=(string)I420,width=(int)640, height=(int)480' ! omxh264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! filesink location=test.h264 -e
VLC can play the file correctly at 30fps and reports as codec: H264-MPEG-4 AVC (part 10) (h264). The fan on top of the SoC didn't turn on.

Codecvisa reports a bitrate of 7.96Mbps when the variable mode is selected on the encoder.
ARM consumption is 45.4% of one core (4 cores available 400% - this means something like 16.75% of the total). However, only the capture is 11.25% so the h264 consumes 5.5%

videotestsrc
ARM load: 156% but only videotestsrc consumes 100%. According to the NVIDIA forum when using videotestsrc the system is also doing memory copies to feed the encoder with NVMM memory buffers so that loads more the ARM.

VLC can play the file correctly at 30fps and reports as codec: Google/On2's VP8 Video (VP80). The fan on top of the SoC didn't turn on.
