Gstreamer not working in GLSDK 7.03

Hi Shylesh,

Can you try with playbin first?

gst-launch-1.0 playbin uri=file:///usr/share/sample.mpg video-sink=kmssink

With explicit pipeline, try with qtdemux instead of mpeggstdemux

Hello Ramprasad,

Thanks a lot for your reply.

When I tried with the playbin, with the following command, "gst-launch-1.0 playbin uri=file:///usr/share/sample.mpg video-sink=kmssink"

I get only the Audio working. But my video isn't playing.

I get this message in my terminal:

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
[  328.344357] omap-iommu 55082000.mmu: 55082000.mmu: version 2.1
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstAudioSinkClock


When I tried with the explicit pipeline, using the following command 
"gst-launch-1.0 location=sample.mpg typefind=true ! qtdemux name=demux demux.video_00 
! queue ! mpegvideoparse ! decodebin ! kmssink 
demux.audio_00 ! queue ! faad ! alsasink"

I get the following error.

ERROR: pipeline could not be constructed: Unrecoverable syntax error while parsing pipeline location=/opt/work/sample.mpg

 And also, please let me know whether I have to download any library files and cross compile them, so that my Application code works.

Thanks in advance,

Shylesh S

Hello,

You could check this user guide:
processors.wiki.ti.com/.../DRA7xx_GLSDK_Software_Developers_Guide

Could you attach the full log by adding --gst-debug=3.

Could you try in location=sample.mpg property to add the full path to the file?

Could you try to play the video file without the audio part?

Let us know the result.

Hello Margarita,

Thanks for the support.

I am new to GStreamer. So, Please guide me over this issue. Could you please tell me any video file source which will work with GLSDK 7.03 (GStreamer v1.2). Because, I keep testing with my same sample.mpg file.

I have added the responses of the questions you asked in your last reply.

1. When I add “--gst-debug=3”, I get the below ERROR.

0:00:00.044078274  1760    0xb3380 WARN default ./grammar.y:902:priv_gst_parse_yyerror: Error during parsing: syntax error,

typefind=true ! qtdemux name=demux demux.video_00 ! queue ! mpegvideoparse ! decodebin ! kmssink demux.audio_00 ! queue ! Faad !.

2. I went throught the USER's GUIDE for DRA7xx. And I ran these commands.

i. gst-launch-1.0 playbin uri=file:///opt/work/sample.mpg 
video-sink=kmssink audio-sink=alsasink
For which, I get these following prints with AUDIO ONLY Playing.

	New clock: GstAudioSinkClock

ii. gst-launch-1.0 playbin uri=file:///opt/work/sample.mpg video-sink=waylandsink
 audio-sink=alsasink"
 For which, I get the following print with no response.
	Setting pipeline to PAUSED ...
	ERROR: Pipeline doesn't want to pause.
	ERROR: from element /GstWaylandSink:waylandsink0: Could not initialise Wayland output

3. When I try playing the video file without the Audio part with the following command, 
Even then I get the Audio only working.

“ gst-launch-1.0 playbin uri=file:///opt/work/sample.mpg video-sink=waylandsink”

4. When I tried to use the Location property with the following command,
“gst-launch-1.0 location=/opt/work/sample.mpg video-sink=kmssink audio-sink=alsasink”
I get an error with the following print,
ERROR: pipeline could not be constructed: Unrecoverable syntax error 
while parsing pipeline location=/opt/work/sample.mpg 
video-sink=kmssink audio-sink=alsasink .


Kindly help me,
Thanks and Regards,

Hi Margarita,

Result:

Hi Margarita,

I tried it.

Hi Margarita,

You've mentioned "yuv" but the old pipeline had "YUY2"? Which one to use?

And, yes I use HDMI to play this. The same HDMI display works in GLSDK 6.04 booted SD Card. The working of it is already checked. But I find no video being played with this GLSDK 7.03 (GStreamer v1.2).

 Response of this pipeline is,

(gst-launch-1.0:1748): GStreamer-WARNING **: 0.10-style raw video caps are being created. Should be video/x-raw,format=(string).. now.

0:00:00.052456421  1748    0xc7160 ERROR           GST_PIPELINE ./grammar.y:624:gst_parse_perform_link: could not link videotestsrc0 to kmssink0

Hi Margarita,

I did go through the threads that you sent.

Today I did search for video sinks through gst-inspect-1.0 | grep "video sink". I happened to see one (fbdevsink).

Then, I tried this pipeline. And saw that Audio worked perfectly. Video also played. But, with lots of glitches and very slow.

gst-launch-1.0 playbin uri=file:///opt/work/sample.mpg 
video-sink= fbdevsink audio-sink=alsasink

I do not know the reason why this Glitches occur. Kindly help me. 
I then tried to use this sink with the following pipeline. 

gst-launch-1.0 filesrc location=sample.mpg ! mpegpsdemux 
name=dmux dmux. ! queue ! mpeg4videoparse !  
ducatimpeg4dec ! fbdevsink dmux. ! queue ! faad ! alsasink

But, I get errors saying that the decoder, parser, and sink in various
combinations don't link eachother. 

Please guide me through this. 

Thanks a lot,
Shylesh S.

I get continuous prints like this when I use that pipeline. Kindly help!

Hello,

What about
viddec3test -s 12:1360*768 sample.mpg --fps 30
is it working?

Are you using the default GLSDK or you made some changes?
Are you using EVM or it is custom board?

Did you try these pipelines:
gst-launch -v filesrc location=input.mpg ! mpegtsdemux ! queue ! h264parse ! ducatih264dec ! kmssink connector=12

filesrc location=input.mpg ! mpegtsdemux name=dmux dmux. ! queue ! h264parse ! ducatih264dec ! kmssink connector=12
dmux. ! queue ! faad ! alsasink

Hello Margarita,

None of these pipelines are working. When I use 4 instead of 12 in "viddec3test -s 12:1360*768 sample.mpg --fps 30", I get no errors. But my video is not getting played.
Yes, I do use the default GLSDK only, and I didn't make any changes. I use EVM board only.

mpegtsdemux plugin is not available in GLSDK 7.03. Only mpegpsdemux, tsdemux are available. But, the video is not working in any of the pipelines.

Hello,
