encode video with gstreamer

Hi.

Our next goal is to encode video. Gstreamer seems to be the most suitable for us. I try to use the following pipeline, but with no luck.

root@dm814x-evm:~# gst-launch -v videotestsrc ! 'video/x-raw-yuv, width=1920, height=1080, format=(fourcc){NV12}, framerate=30/1' ! omx_h264enc ! 'video/x-h264'
 ! queue ! gstperf ! filesink location=colorbar.264 sync=false
Setting pipeline to PAUSED ...
vmap allocation for size 197136384 failed: use vmalloc=<size> to increase size.
gst-launch-0.10: DomxProcMgrIf_HLOS.c:316: DomxCore_mapPhyAddr2UsrVirtual: Assertion `(status >= 0)' failed.
Aborted

I found this pipeline on the forum. But i didn't find any recommended example to encode video. Can anyone suggest for sure working pipeline?

Here are bootargs: mem=169M notifyk.vpssm3_sva=0xBF900000 mem=170M@0xA0000000

Ezsdk is ti-ezsdk_dm814x-evm_5_04_00_11.

Best regards,

Alexander Vasiljev.

    Hello,

    You could try examples, like:

    gst-launch -v videotestsrc ! 'video/x-raw-yuv, width=1920, height=1080, format=(fourcc)NV12, framerate=30/1' ! omx_h264enc ! 'video/x-h264' ! gstperf ! filesink location=colorbar.264 sync=false

    or

    gst-launch videotestsrc is-live=true ! video/x-raw-yuv,framerate=60/1 ! clockoverlay auto-resize="0" shaded-background=true time-format="%y %j %H:%M:%S" !    gstperf ! omx_h264enc ! mpegtsmux ! filesink location=test.tsmux

    Both are working with default bootargs:

    New clock: GstSystemClock
    perf0: frames: 65     current: 64.13     average: 64.13    arm-load: 21
    perf0: frames: 125     current: 59.98     average: 62.07    arm-load: 61
    perf0: frames: 186     current: 60.04     average: 61.39    arm-load: 59
    perf0: frames: 246     current: 60.00     average: 61.04    arm-load: 70
    perf0: frames: 306     current: 59.99     average: 60.83    arm-load: 62
    perf0: frames: 367     current: 59.98     average: 60.69    arm-load: 61


    Let me know the result.

    Best Regards,

    Margarita

    Hi, Margarita.

    It works! I had lost vmalloc in bootargs. I returned "vmalloc=500M" and it works.

    Best regards,
