Friends,

I am trying to play 1920x1080p videos on my DM8148 EVM(PG2.1_B) using gstreamer,

details of my setup are as follows,

EZSDK = 5.03.00.09

gstreamer svn version=983(TAG_DM81XX_RELEASE_0_03)

h/w DM8148 EVM(PG2.1_B)

I used following link for setting-up the gstreamer for my target.

https://gstreamer.ti.com/gf/project/gstreamer_ti/scmsvn/?action=browse&path=%2Ftrunk%2Fgstreamer_ti_dm81xx%2FREADME.TXT&revision=973&view=markup

here is the 24fps file details

'ffmpeg -i sample_1080p24.mp4' this command prints following details

Seems stream 1 codec frame rate differs from container frame rate: 48.00 (48/1) -> 24.00 (24/1)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'sample_1080p24.mp4':

Stream #0.1(und): Video: h264, yuv420p, 1920x1080, 24 tbr, 24 tbn, 48 tbc

here is the gstreamer pipeline for 24fps file

Result: file plays well including both audio and video

here is the 60fps file details(downloaded from http://www.megaupload.com/?d=PBVL1I4E)

'ffmpeg -i sample_1080p60.mp4' this command prints following details

Result: nothing is played and i see the following error message

"Stream is corrupt error, ignorable ..."

can someone point me if there is any mistake in gstreamer pipeline of 60fps video?

thanks,

Albert.

Hi Albert,

Could you tell me the level of the 1080p60 stream.

ALso would it be possible to host the 1080p60 stream over an ftp ?

Iam unable to dl the file from behind our firewall :(

Regards,

Prashant.

Hi Albert,

This stream seems to be level 5.0. Currently the gstreamer video decoder element creates h264 video decoder with default level which is level 4.2 and hence can only decode level 4.2 streams. We will be fixing this issue where we will be adding a property to gst video decoder element to set the MAX level and profile for the decoder creation.

Thanks,

Satish

Hello Satish Arora and all :

There is maybe some problem on decoding Streaming H.264 video media content from on-board Ethernet port of DM8148 EVM . The details of the problem are the followings. Now,I doubt may be h264parse and omx_h264dec will have some problem, Is there anyone can tell me what could be the cause of the problem and how to fix them?Thanks so much!

If DM8148 gstreamer pipeline start before VLC streaming out, the streaming video playback will OK

Case 2:

If VLC streaming out first then DM8148 gstreamer pipeline start, the streaming video playback will always have wrong decoded frame order problems.and the video is

dithering.

2、Second difference

The first:

incoming buffer: nFilledLen: 881632, nOffset: 21536 nFlags: 50000

and the second:

incoming buffer: nFilledLen: 881632, nOffset: 21536 nFlags: 50200

3. the third difference

the second always turn out:

/GstPipeline:pipeline0/GstOmxH264Dec:omxh264dec0.GstPad:src: caps = video/x-raw-
yuv-strided, width=(int)720, height=(int)576, format=(fourcc)NV12, rowstride=(in
t)896, interlaced=(boolean)false, framerate=(fraction)0/1
Stream is corrupt error, ignorable ...

And:

When I use the same gstreamer cmd to test on PC platform,all is OK,the video was played very well,

On PC ,the cmd is :

So,comparing to on DM814x,the difference is :

'video/x-h264' ! ffdec_h264 ! ffmpegcolorspace ! videoscale ! queue ! xvimagesink-------------------PC

and

h264parse access-unit=true ! omx_h264dec ! omx_mdeiscaler ! 'video/x-raw-yuv,width=800,height=480' ! omx_ctrl ! omx_videosink

---------On Dm814x

SO,Wheather the h264parse or omx_h264dec or omx_mdeiscaler may be have some problem.

Thanks very much .
