DM814x GStreamer OMX Encoding in MPEG2, MPEG4, MJPEG

Danny Cullen
Intellectual 510 points


Hi all,

I can get a gstreamer pipeline to capture using V4L2 and encode using the 'omx_h264enc' component.  Can someone tell me if there are other GSTreamer OMX components to encode into MPEG2, MPEG4 or MJPEG?  These encoding formats are all supported by the HDVICP2, I'm just wondering how I actually use them!?

Regards,

Danny Cullen

    You could check in:

    ti-ezsdk_dm814x-evm_5_05_02_00/component-sources/gst-openmax_GST_DM81XX_00_07_00_00/omx

    also you could check in:

    gstomx.c

    or

    ti-ezsdk_dm814x-evm_5_05_02_00/component-sources/gst-openmax_GST_DM81XX_00_07_00_00

    Hi Margarita,

    Thanks for the reply.  I checked the pdf documents and they don't specifically mention MPEG4/MJPEG encoding is supported or not.

    In 'gstomx.c', there is a commecnted out line:

    //    { "omx_mpeg4enc",       "libOMX_Core.so",           "OMX.TI.DUCATI.VIDENC",  NULL,                   GST_RANK_PRIMARY,   gst_omx_mpeg4enc_get_type },

    I'm therefore assumming that this isn't supported?  If so, are there any plans in upcoming TI GStreamer releases to make this available?

    Regards,

    Danny

    Hello,

    I will check and I will let you know.

    You could try to remove the comment. Rebuild the gstreamer.

    You could use these pipelines for tests:

    gst-launch -v videotestsrc ! 'video/x-raw-yuv, width=1920, height=1080, format=(fourcc)NV12, framerate=60/1' ! omx_mpeg4enc  !  filesink location=colorbar.mp4

    gst-launch -v filesrc location=colorbar.mp4 ! mpeg4videoparse ! omx_mpeg4dec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 !  omx_videosink

    Hi Margarita,

    I have uncommented the omx_mpeg4enc declaration and am rebuilding now.  I'll feed back in an hour or so on the status.

    There must be a reason why it was commented out though?  Or it it just an untested component from a TI GStreamer point of view?

    Regards,

    Danny

    Hi Margarita, I was diverted onto a different activity so I nver got around to testing.  I will feedback one the MPEG4 encoding is complete.

    Margarita,

    I tested the 'omx_mpeg4enc' GStreamer element without success.  These were the pipelines I used:

    gst-launch v4l2src device=/dev/video5 always-copy=false queue-size=12 ! \ video/x-raw-yuv-strided,format=\(fourcc\)NV12,width=1920,height=1080,framerate=\(fraction\)60/1 ! omxbufferalloc numBuffers=12 ! omx_mpeg4enc ! video/mpeg,mpegversion=4 ! \ gstperf ! filesink location=sample.mpeg4 sync=false

    gst-launch --gst-debug=3 --gst-debug-no-color v4l2src device=/dev/video5 always-copy=false queue-size=12 ! \ video/x-raw-yuv-strided,format=\(fourcc\)NV12,width=1920,height=1080,framerate=\(fraction\)60/1 ! omxbufferalloc numBuffers=12 ! omx_mpeg4enc ! video/mpeg,mpegversion=4 ! \ gstperf ! filesink location=sample.mpeg4 sync=false

    With no debugging, it failed with the error "unrecoverable error: One or more parameters were not valid (0x80001005)".  Please see this log,

Segmentation fault

    This all leads me to believe that the 'omx_mpeg4enc' element is untested?  I'm using SDK 05.05.02.00 and the GStreamer sources pulled from https://gstreamer.ti.com/svn/gstreamer_ti/trunk/gstreamer_ti_dm814x.

    Is this something which is currently being tested/developed?  Any release dates as to when it will be fully supported?

    Just for sanity, I retested my V4L2 capture and H264 encode and it still works like a charm so no major issues there.

    Kind regards,

    Danny Cullen

    Could you remove framerate=\(fraction\)60/1 from the pipeline and try again. I have some suspicious. Let me know the result.

    Hi Margarita,

    I finally got around to testing again without success.  Removing the 'framerate=\(fraction\)60/1' part from the gstreamer pipeline had no effect.  I still get the same errors as before.

    Do you have any other suggestions?  Have you seen this work in your system?

    For your information, I tried the pipeline below and it did work and encode.  Does this tell you anything about why it doesn't work with a 'real' V4L2 input?  The obvious differences in the pipeline are that it's not using OMX allocated buffers or a strided capture buffer.

    gst-launch videotestsrc num-buffers=1000 ! video/x-raw-yuv,format=\(fourcc\)NV12,width=1920,height=1080,framerate=\(fraction\)60/1 ! omx_mpeg4enc ! video/mpeg,mpegversion=4,systemstream=false ! gstperf ! filesink location=sample.mpeg4

    Kind regards,

    Danny

    Hello Danny,

    Could you check this topic and apply the patch for gstomxbufferalloc.c

    Hello,

    This topic is very old, please open a new one with information about the issue that you met, software release, are you using EVM or custom board etc.

    Hello,

    I checked the omx_mpeg4enc.

    Please provide more details about your use case and the issue that you met.

    Here is my observations:

    Pipeline for tests:

    gst-launch videotestsrc num-buffers=1000  ! omx_mpeg4enc ! video/mpeg,mpegversion=4,systemstream=false ! filesink location=mpeg4enc.m4v

    Decoding the stream:

    root@dm814x-evm:~# gst-launch filesrc location=mpeg4enc.m4v ! mpeg4videoparse  !
      omx_mpeg4dec  ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf  !  omx_videosink
