Hi Felipe, After debugging I found that memory map is failed in the start function of omapfb.c file. Can you guide me what other things are missing ? Thanks In Advance, Tejas. -----Original Message----- From: Felipe Contreras [mailto:fel...@gm...] Sent: Wednesday, February 17, 2010 4:46 PM To: Tejas Cc: gst...@li...

Ah, I see. Have you got omapfbsink to do anything? Maybe the fb overlays haven't been setup properly. Where did you get the omapfbsink element? -- Felipe Contreras |

Ah, I see. Have you got omapfbsink to do anything? Maybe the fb overlays haven't been setup properly. Where did you get the omapfbsink element? -- Felipe Contreras |

HI Felipe,
If I use following pipe line it will work fine.
"gst-launch-0.10 filesrc location=/media/mmcblk0p1/Movie.mp4 ! mpeg4parser ! mpeg4dec ! ffmpegcolorspace ! fbdevsink"
Here mpeg4parser and mpeg4dec are my Plugins which I made. Capability of both are as followed.
MPEG4PARSER ::
============
SINK template: 'sink'
Availability: Always
Capabilities:
video/picus-mpeg4parser
width: [ 1, 2147483647 ]
height: [ 1, 2147483647 ]
framerate: [ 0/1, 2147483647/1 ]
mpegversion: 4
systemstream: false
SRC template: 'src'
Availability: Always
Capabilities:
video/picus-mpeg4dec
MPEG4DEC ::
=========
Pad Templates:
SINK template: 'sink'
Availability: Always
Capabilities:
video/picus-mpeg4dec
width: [ 1, 2147483647 ]
height: [ 1, 2147483647 ]
framerate: [ 0/1, 2147483647/1 ]
SRC template: 'src'
Availability: Always
Capabilities:

Src pad of mpeg4dec will be connected with ffmpegcolorspace and later will be connected with fbdevsink and complete pipeline will be settled.
But instead fbdevsink if I use omapfbsink I can not create pipeline and getting following error.

I'm not sure 'mpeg4parser' is the right element, probably you want qtdemux.

You can try to run with this:
export GST_DEBUG=2
To find out warnings and errors.

Hello All,
I have taken up libgstticodecplugins.so to my library path
and following command is applied.
Gst-launch-0.10 filesrc location=1.mp4 ! mpeg4parser ! mpeg4dec !
ffmpegcolorspace ! TiDmaiVideoSink
But I am getting following error.
"CMEM Error: init: Failed to open /dev/cmem: 'No such file or directory'
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
Setting pipeline to NULL ...
FREEING pipeline ."
Please guide me where I am wrong.
Thanks In Advance,

If you are using a GNOME like environment then most probably you can configure which sink to use with GConf, if not, you can recompile omapfbsink with a higher rank (like primary + 10). That should do the trick. Cheers. -- Felipe Contreras |

Hi Felipe, Nice to have reply from you. I have gone through gst-omapfb plugin from your git repository of gst-omapfb. I find it works on omap frame buffer and accept format as "UYVY". So I can give my decoder output in the form of "UYVY". I have one question, when I run my Plugins as gst-launch, I can run VGA and also HD file smoothly. But when I run into totem movie player, I can't run 320X240 video file smoothly.

GStreamer would find out if there's any conversion needed (of the elements are implemented properly). Maybe you should give a try to gst-omapfb which renders directly into the framebuffer into a YUV overlay. Unfortunately the OMAP3 display subsystem doesn't support I420 so you would need some conversion for sw codecs. Or you can try to use the DSP accelerated codecs which have an accelerated converter. > I want to improve performance on beagle board. If I run my > codec only then I can run HD file also.

Hello folks, We are considering trying to move our plugin to the main GStreamer source code repository, and could really use some help identifying the most important things we should be thinking about if we want to make this happen. Our plugin has existed as its own GForge project since February 2009 located at http://gstreamer.ti.com. The goal of this project is to provide a GStreamer plugin that enables hardware accelerators, V4L2 display, and the transparent use of DSP codecs on a wide variety of TI devices. This is accomplished by using TI's DMAI/Codec Engine/DSPLink framework. Our immediate benefit from the initial effort was that we were able to leverage AV sync capabilities from GStreamer, as well as seamless integration with the rich assortment of plugins available. As time goes on, we would also like to flesh out the remaining functionality required to enable features such as trickmode playback (which is currently an ongoing effort on a development branch). Jason Kridner made an inquiry about setting up a repository in late 2007, located here: http://bugs.freedesktop.org/show_bug.cgi?id=13098 The result was that we were given a repository under the condition that we run our first few patches by the mailing list. No action has been taken yet on our end for this, as there are a few things about our plugin that we're concerned will meet some resistance: 1) In order to build our plugin, you need to use proprietary TI software. Some of the tools required are freely available, but others are still only available to customers. 2) We do not yet have an automated test suite, and even if we did, the tests will need to be run on hardware that not everyone has available. 3) We have not yet implemented support for all events, we currently use posix-threads directly in some places to enable real-time scheduling for DSP codec handlers, and our resource-management isn't always handled in the correct state transitions (some of which can't be helped). We are working towards making our plugin behave more in accordance with the spec, but are not there yet. It would be much appreciated if you could help us to identify the main blockers that absolutely must be taken care of before we can start submitting patches and migrating our source code repository. Thanks and best regards, Don Darling |

Hello, I am trying to implement Fast Forward technique in my Gstreamer based Player. I am using IMX27 based system and following versions of Gstreamer code. Gstreamer-core: 0.10.22 Base: 0.10.22 Good: 0.10.10 I am streaming the media from a remote server on to my device. What is the best method to implement Fast Forward in the case of network streams ? Is there a way, the application tells the remote side to give only I-frames so that the display on the Player looks as if Fast forwarding is being implemented. Does this need support from Encoder too ? Right now, I am trying to SEEK repeatedly using FLUSH and SKIP flags, but every seek takes 4 seconds to complete and the inter-frame gap is 4 seconds which is too much for a Player. IS there a way to reduce this ? regards, Rajesh Marathe. |

Hello All,
I am working on application GStreamer on Beagle Board. For
that I have built angstrom image online from angstrom web site and also
enabled totem movie player.
When I run totem and start playback of mpeg4 video file. It
is very slow and choppy. I am not able to run 320 X 240 video file smoothly.
I found that totem is using playbin and pipeline is created
as followed.
Decodebin ! mpeg4parser ! mpeg4dec ! ffmpegcolorspace !
xvimagesink/ximagesink (Here mpeg4parser and mpeg4dec are my Plugins). Now
when I do top command max usage(almost 90 %) of cpu is acquired by totem and
also max amount of memory also. I found that max time is taken into scaling
part of ximagesink/xvimagesink.
Now alternatives for ximagesink/xvimagesink I am thinking for
TIDmaiVideoSink and omapdmaifbsink Plugins from ticodecplugins. I am doubt
if I remove ximagesink and xvimagesink from my librarypath and instead put
ticodecplugins will totel detect display and color space conversion Plugins
?
I want to improve performance on beagle board. If I run my
codec only then I can run HD file also. But in totem I can't run 320 X 240
file smoothly.
If anyone can help me to improve this performance ?
If anywhere I am wrong or misunderstood , please guide me and
correct me.
Thanks In Advance,
Tejas.

Hi, The link provided by felipe has baseparse imeplementation for the parser and will help you in understanding.. Go through the code of baseparse and you will get the idea of parse calls. Ved.

Thanks a lot Felipe but my basic intention is to study how parser function calls are made by gstreamer so that I can understand complete functing of existing AMR parser. If any person have any reference to it , Kindly share the same.

Hi friends, I have to write a parser of AMR files. I have never written any parser though I have some experience in writting a decoder plugin. I even explored plugin writer guide but i dint find any useful info related to parser. Kindly tell me if you have any info or reference to the same. thanks 2010/1/28 kedahanzi <ked...@16...> > hello, > i am new to gstreamer, i need to write a TS flow media palyer, but i > can't get some examples about how to use > gstreamer. > > much thanks > > 2010-01-28 > ------------------------------ > kedahanzi > > > ------------------------------------------------------------------------------ > The Planet: dedicated and managed hosting, cloud storage, colocation > Stay online with enterprise data centers and the best network in the > business > Choose flexible plans and management services without long-term contracts > Personal 24x7 support from experience hosting pros just a phone call away. > http://p.sf.net/sfu/theplanet-com > _______________________________________________ > Gstreamer-embedded mailing list > Gst...@li... > https://lists.sourceforge.net/lists/listinfo/gstreamer-embedded > > |
