Maybe this should go to general gstreamer mailing list. But anyway, you should look at other code wrappers in gstreamer and write a simmilar plugin that wrapps your decoders.

Hello All,
I am involved in the reasearch programme for my company. I would like to decode .mp4 which contains video container as .h264 and .mpeg4 on beagle board. I do not want to use opensource ffmeg codecs, instead we have developed own video codec library and have our own apis for the same. I have cross compiled gstreamer with the help of sbox2 for beagle board. Now i want to integrate our codec library to openmax and gstreamer. But i am not getting much details. Can anyone help me out into my research project?
Waiting for your kind response.
NOTE :: We are not using hardware(DSP) for decoding of streame, instead we have our own video codec which is software based.
Thanks In Advance,
Tejas. |

It definitely seems to be a very nice effort that will be very useful to many projects. I will integrate on the Touch Book.

Hi, This is the first public release of gst-dsp; a native GStreamer plug-in to access Texas Instruments' DSP algorithms for OMAP3 platforms. The code came originally from a series of TI projects: tiopenmax[1], and libbridge[2]. gst-dsp replaces these two layers and talks directly to the DSP bridge driver. The main advantages are code simplification (5k vs 50k), and better performance (at least 4 times less CPU usage). However, not all of the codecs have been implemented, only MPEG-4 and H.263 video encoders and decoders, the JPEG encoder, and H.264 is partially supported. Currently it's used in the Nokia N900. In order to make it easier for people to try it out, I created a demo image for the beagleboard with all the required components: GStreamer, gst-dsp, DSP public binaries, and a kernel with DSS2 and DSP bridge driver. The linux kernel (DSS2 + dspbridge) is at the v2.6.32-felipec1 tag in: http://gitorious.org/~felipec/linux-omap/felipec The DSP algorithms are public, and come from tiopenmax: https://gforge.ti.com/gf/download/frsrelease/170/1399/tiopenmax-0.3.5.tar.gz Here's the demo rootfs with the kernel image and instructions: http://people.freedesktop.org/~felipec/beagle-2.6.32-rc3/ And here's the video showing it on action for both playback and recording: http://www.youtube.com/watch?v=SN-Nw_yDQUs The main repository is hosted on github: http://github.com/felipec/gst-dsp And there's also one specific for maemo: http://maemo.gitorious.org/maemo-multimedia/gst-dsp This code wouldn't have been possible without all the contributions and specially thanks to TI for making their code open source. Here's the shortlog for 0.6.0: Andriy Shevchenko (1): base: fix a crash on send codec data Felipe Contreras (180): Initial commit Register dsp node Add README Fix and update copyrights Add

Hi Felipe,
I would like to retrieve the clock time in gst-openmax.
When I used gst_clock_get_time(self) in output_loop, I am getting error.
GStreamer-CRITICAL **: gst_clock_get_time: assertion `GST_IS_CLOCK (clock)' failed
Could you let know how to get the clock time using gst_clock_get_time() API.
Thanks,
Jai

Working with OpenMAX IL that's usually the reason for things not working as they should: the implementation doesn't follow the spec properly. Ideally you would push your vendor to fix their implementation, but most probably first you'll have to implement some workarounds. If you think those workarounds can somehow be safe for other implementations please send the patches to the mailing list. Cheers. -- Felipe Contreras |

By way of strace and a few debug prints, I have found that our third-party supplier has implemented the OpenMAX specification a bit differently. It seems the problem with the pipeline not pausing was actually an issue with a parameter being required for OMX_Init(). So I have gotten past this issue and am now working my way through the rest of their changes. I suppose I should have dug a little more deeply before posting my question. Thanks again for your time, John Bivens |

Hello, (This is my first post to this list, so please let me know if I [unintentionally] break any rules...) A little background: I currently have some openmax libraries from a third-party supplier (unfortunately binary-only, non-free software). I would like to integrate them into the GStreamer framework using gst-openmax on an ARM11 system based on Wind River Linux. I have cross-compiled the GStreamer framework, various GStreamer plugins, and gst-openmax. I have also altered the element_table in gstomx.c to utilize th third-party libraries and reference the proper component names. So far, so good -- I think. When attempting to run a fakesrc through one of the openmax libraries and back out to a fakesink, I get the following error: # gst-launch fakesrc ! omx_h264dec ! fakesink Setting pipeline to PAUSED ... ERROR: Pipeline doesn't want to pause. Setting pipeline to NULL ... FREEING pipeline ... When executing the same command with a gst-openmax debug level of 5 (GST_DEBUG="omx:5"), I get the following: # gst-launch fakesrc ! omx_h264dec ! fakesink 0:00:00.443705000 1047 0x15050 LOG omx gstomx_base_filter.c:878:type_instance_init:<GstOmxBaseFilter@0x94848> begin 0:00:00.446431000 1047 0x15050 LOG omx gstomx_base_filter.c:917:type_instance_init:<GstOmxBaseFilter@0x94848> end Setting pipeline to PAUSED ... 0:00:00.452901000 1047 0x15050 LOG omx gstomx_base_filter.c:95:change_state:<omxh264dec0> begin 0:00:00.453392000 1047 0x15050 INFO omx gstomx_base_filter.c:99:change_state:<omxh264dec0> changing state NULL - READY 0:00:00.454123000 1047 0x15050 LOG omx gstomx_base_filter.c:153:change_state:<omxh264dec0> end ERROR: Pipeline doesn't want to pause.

Unfortunately, this does not give me much information to go on -- or at least I don't see much there that could help. If I set the GStreamer debug level to 4 or 5 (GST_DEBUG="4" or GST_DEBUG="5"), output runs in an endless loop, and of course does not result in the desired playback. When setting the GStreamer debug level to 3 (GST_DEBUG="3"), however, I get a segmentation fault at the point where the pipeline is created: # gst-launch fakesrc ! omx_h264dec ! fakesink 0:00:00.001167000 1053 0x15050 INFO GST_INIT gst.c:608:init_pre: Initializing GStreamer Core Library version 0.10.21 0:00:00.002487000 1053 0x15050 INFO GST_INIT gst.c:609:init_pre: Using library installed in /usr/lib 0:00:00.002940000 1053 0x15050 INFO GST_INIT gst.c:619:init_pre: Linux (none) 2.6.27.18 #2 PREEMPT Thu Jun 11 13:16:50 JST 2009 armv6l 0:00:00.004297000 1053 0x15050 INFO GST_INIT gstquery.c:103:_gst_query_initialize: init queries 0:00:00.017659000 1053 0x15050 INFO GST_INIT gstmessage.c:73:_gst_message_initialize: init messages 0:00:00.020762000 1053 0x15050 INFO GST_PLUGIN_LOADING gstplugin.c:257:_gst_plugin_initialize: registering 0 static plugins 0:00:00.023976000 1053 0x15050 INFO GST_PLUGIN_LOADING gstplugin.c:242:gst_plugin_register_static: registered static plugin "staticelements" 0:00:00.024569000 1053 0x15050 INFO GST_PLUGIN_LOADING gstplugin.c:244:gst_plugin_register_static: added static plugin "staticelements", result: 1 0:00:00.029336000 1053 0x15050 INFO GST_INIT gst.c:901:ensure_current_registry: reading registry cache: /root/.gstreamer-0.10/registry.arm.bin 0:00:00.196823000 1053 0x15050 INFO GST_REGISTRY gstregistrybinary.c:1241:gst_registry_binary_read_cache: loaded /root/.gstreamer-0.10/registry.arm.bin in 0.166966 ses 0:00:00.200272000 1054 0x15050 INFO GST_INIT gst.c:671:scan_and_update_registry: Validating registry cache: /root/.gstreamer-0.10/registry.arm.bin 0:00:00.222455000 1054 0x15050 INFO GST_INIT gst.c:738:scan_and_update_registry: Registry cache has not changed 0:00:00.223757000 1053 0x15050 INFO GST_INIT gst.c:944:ensure_current_registry: registry reading and updating done, result = 1 0:00:00.224632000 1053 0x15050 INFO GST_PIPELINE gstparse.c:291:gst_parse_launch_full: parsing pipeline description 'fakesrc ! omx_h264dec ! fakesink ' 0:00:00.264331000 1053 0x15050 INFO GST_PLUGIN_LOADING gstplugin.c:562:gst_plugin_load_file: plugin "/usr/lib/gstreamer-0.10/libgstcoreelements.so" loaded 0:00:00.265127000 1053 0x15050 INFO GST_ELEMENT_FACTORY gstelementfactory.c:399:gst_element_factory_create: creating element "fakesrc" 0:00:00.266501000 1053 0x15050 INFO GST_ELEMENT_PADS gstelement.c:639:gst_element_add_pad:<GstBaseSrc@0x8c000> adding pad 'src' 0:00:00.336663000 1053 0x15050 INFO GST_PLUGIN_LOADING gstplugin.c:562:gst_plugin_load_file: plugin "/usr/lib/gstreamer-0.10/libgstomx.so" loaded 0:00:00.337540000 1053 0x15050 INFO GST_ELEMENT_FACTORY gstelementfactory.c:399:gst_element_factory_create: creating element "omx_h264dec" 0:00:00.339162000 1053 0x15050 INFO GST_ELEMENT_PADS gstelement.c:639:gst_element_add_pad:<GstOmxBaseFilter@0x95848> adding pad 'sink' 0:00:00.339718000 1053 0x15050 INFO GST_ELEMENT_PADS gstelement.c:639:gst_element_add_pad:<GstOmxBaseFilter@0x95848> adding pad 'src' 0:00:00.340641000 1053 0x15050 INFO GST_ELEMENT_FACTORY gstelementfactory.c:399:gst_element_factory_create: creating element "fakesink" 0:00:00.341886000 1053 0x15050 INFO GST_ELEMENT_PADS gstelement.c:639:gst_element_add_pad:<GstBaseSink@0x960e0> adding pad 'sink' 0:00:00.343238000 1053 0x15050 INFO GST_ELEMENT_FACTORY gstelementfactory.c:399:gst_element_factory_create: creating element "pipeline" Caught SIGSEGV accessing address (nil) Spinning. Please run 'gdb gst-launch 1053' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core. To me, this seems as if the libraries themselves are problematic -- perhaps they are not truly openmax-compliant, or they are poorly coded, or something else is amiss. Because of the non-free, binary-only nature of the libraries, I cannot even begin to debug them. Does anyone see something here that might indicate the possibility of another avenue of exploration (besides debugging the proprietary libraries themselves)? Is this something that occurs with other openmax library implementations? Or could someone give me some other pointers or information that may lead me in the right direction? I am also including the output of gst-inspect here, in case it may be of use: # gst-inspect omx: omx_mp3dec: OpenMAX IL MP3 audio decoder omx: omx_h264enc: OpenMAX IL H.264/AVC video encoder omx:

Hi all, I have installed gstreamer in my system and developed applications few months back as a complete package. Now since my folder structure is changed, I am not able to run my application. What might be cause?? . I hope once again I should not install once again. I have set PKG_CONFIG_PATH variable to pkgconfig folder. If I do gst-inspect it is showing only two static elements. Help me.. Thank you, Raghu |

The opkg-native package failed to compile because of gcc's -Werror flags.

That's not a gst-openmax issue. You can ask in gstreamer-devel mailing list, but most probably they'll point out 'man gst-launch' http://linux.die.net/man/1/gst-launch-0.10 You'll see examples of pipelines you can run in your laptop, if you try some of those you'll notice you are missing a demuxer element.

Hi Daniel, Hi Felipe, first of all, thanks for your quick and useful replies. I set up Poky for the BeagleBoard as specified on wiki page you provided. As a side note: I run into a minor issue building the poky image. The opkg-native package failed to compile because of gcc's -Werror flags. I worked around this by altering meta/conf/distro/include/poky_fixed_revisions.inc, setting SRCREV_pn-opkg-native to "4671" instead of "4545". See also this page: http://lists.o-hand.com/poky/0677.html. Perhaps something to put on the wiki? After building, I copied the /lib/dsp folder from tiopenmax-0.3.5 to my file system, as well as the DSP bridge binaries (including the ping test). Running the ping test yields the same result as before. When I try to decode my MPEG4 video, I get a bit further then before, but I still get some errors. root@beagleboard:~# gst-launch-0.10 filesrc location = ./simpsons.mp4 ! omx_mpeg4dec Setting pipeline to PAUSED ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock (gst-launch-0.10:779): GStreamer-CRITICAL **: gst_value_set_fraction: assertion `denominator != 0' failed (gst-launch-0.10:779): GStreamer-CRITICAL **: gst_value_set_fraction: assertion `denominator != 0' failed (gst-launch-0.10:779): GStreamer-CRITICAL **: gst_value_set_fraction: assertion `denominator != 0' failed ... the assert keeps coming until I interrupt ... I've googled on this error, but haven't found anything useful. Do you have any ideas? Or can you point me in the right direction to look for a solution? Do you think this is a problem with the packages, or could I be using gstreamer the wrong way?

Hi, I'm currently evaluating the OMAP3530's video capabilities on a Beagle Board. I'm trying but struggling to get Gstreamer to decode an MPEG4 file. The following pages have been my guide so far: http://elinux.org/BeagleBoard/gst-openmax and http://elinux.org/BeagleBoard/DSP_Howto. I'm using the linux-omap kernel from Felipe Contreras ("git checkout -b felipec v2.6.28-felipec1", as shown on the wiki pages) and a root file system built using OpenEmbedded (Angstrom); it's a build of the demo beagleboard image by Koen Kooi (http://angstrom-distribution.org/demo/beagleboard/). I've downloaded the TI OpenMAX IL implementation from here: https://omapzoom.org/gf/project/openmax/frs/. Unlike on the wiki, it's version 0.3.5 instead of 0.3, but I don't expect that to make much difference. I've installed this package and copied the lib/dsp folder to my root file system. Next, I've built libdspbridge, libomxil-ti and gst-openmax, again following the instructions on the wiki. First I was using Scratchbox 2, but I've switched to OpenEmbedded to build the packages because it's easier for me this way to install the files into my rootfs. This doesn't seem to make any difference (and I wouldn't expect it to). Also, I don't see any difference when I use the OpenEmbedded toolchain or a toolchain I've downloaded from CodeSourcery. After starting up the target, first I loaded the kernel driver: modprobe bridgedriver base_img=/lib/dsp/baseimage.dof. To test whether the kernel driver works, I used the ping test mentioned on the wiki. This is where the first odd thing happened - I got the following error: ./ping.out: error while loading shared libraries: libbridge.so.2: cannot open shared object file: No such file or directory I worked around this by making a symlink /lib/libbridge.so.2 to /lib/libbdridge.so. After this workaround, the ping test looked to be working fine: DSP device detected !!

However, I get the following error: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... gst-launch-0.10: symbol lookup error: /lib/libLCML.so: undefined symbol: DspManager_Open After some observation of the source code and binaries, I believe that DspManager_Open is defined in my /lib/libbridge.so file. The LCML lib for some reason can't find it. To me, the odd thing here is that the ping test worked, but that gstreamer complains about DspManager_Open. If I have understood the DSP/BIOS documentation correctly, it's impossible to create a dsp node without having opened the manager. But the ping test is able to open a node without complaining about DspManager_Open. I'm baffled. Can anyone clarify? Am I missing something? Am I doing something wrong here? If you need more information from my part, please ask. Thanks very much in advance |

Hi Stefan,
After changing the Caps of MyDemuxer, MyDecoders,& MySinks filters i am able to load some of filters with playbin.
But except MyAudioSink all other elements are loaded by playbin( MyDemuxer,
MyVideoDecoader, MyVideoSink, MyAudioDecoder). Here no other audiosink
is loaded(eg : Pulsesink etc...).
when i am tested same chain by enableing export GST_DEBUG=GST_ELEMENT_FACTORY:3 log then i came to know that even autoaudiosink not getting loaded.

Due to audiosink not loaded, pipeline is not getting PREROLLED.
Why autoaudiosink not loaded here.
If any one have an idea please reply.
PS: When my filters not registered same chain is working with standard elements.
Thanks & Regards

Hi Stefan,
Here i am giving my debug observations.

I debugged the chain by installing source packages. it is hanging in
file name : gst-launch.c (gstreamer-0.10.22/tools)
Function Name : event_loop() (called from line no:739 from main())
At line no : 382 -->message = gst_bus_poll (bus, GST_MESSAGE_ANY, blocking ? -1 : 0);
I think here it is waiting for message on the bus from different filters and exit condition is
pipeline paused condition. But this is not occuring.
Debug log for command : gst-launch-0.10 -m playbin uri=file:///home/sriram/sample_mpeg4.mp4
is

Is any of your elemnts plugged? You need to go down to the debug log and check if playbin is trying to plug your elements and if not why. If neccesary add more log statement. You divert quite a bit from the standart way of things, unfortunately then you might need to dig deeper by yourself too.

Hi Stefan,
Sorry for late reply ..
* Do the plugins have a rank>0. Otherwise playbin or playbin2 are not
considering them.
* Make sure there are no elements with same or higher rank on the system
where you test
* Make sure that your demux gets choosen. Does it have the right
template caps set on its sink-pad?
Yes. I am taking care of above all .. Filter rank more than 256 and Caps i giving as accept ANY..
and my filter is choosed by chain.
some people replayed that with this architecture (means single filter) i can't able to test with Play-bin. For that reason i am implemented dummy decoders and Sink elements with high priority ranks.
But still i am getting response like previous ...
My final goal is to test my filters with Totem or any gstreamer application.For that what else i should have in my filter chain..
Please help resolve this issue..
Thanks & Regards
