This page provides example pipelines that can be copied to the command line to demonstrate varIoUs GStreamer operations. Some of the pipelines may need modification for things such as file names,ip addresses,etc.
It is our hope that people using this page will add new interesting pipelines that they themselves are using. For example,on DM6467 if you are decoding a 1080 video and outputing to component please include your pipeline for others to use as a reference.
Refer to this Gstreamer article for more information on downloading and building TI Gstreamer elements. The project is hosted athttp://gstreamer.ti.com. If you are interested in understanding the design details then watch video presentationhttp://software-dl.ti.com/sdo/sdo_apps_public_sw/GStreamer_On_TI/FLV1/GStreamer_On_TI.htm
Testing
Currently these pipelines have not undergone any extensive testing. If you find an error in a pipeline please correct it.
Media files
You should be able to use any audio and video media file that conforms to the appropriate standard.
Creating an AVI file
The followingffmpegcommand takes a .mov file (say from the Apple movie trailers site) and make an AVI file. Run the command on your host computer.
ffmpeg -i tropic_thunder-tlr1a_720p.mov -r 60 -b 6000000 -vcodec mpeg2video -ab 48000000 -acodec libmp3lame -s 1280x544 tropic.avi

DM355
This section covers pipelines for common use cases for the DM355 processor.
Environment Requirements
Before executing the pipeline you need to set couple of environment variables,load kernel modules and activate video planes as follows:
cd /opt/gstreamer_demo/dm355/
./loadmodules.sh
export GST_REGISTRY=/tmp/gst_registry.bin
export LD_LIBRARY_PATH=/opt/gstreamer/lib
export GST_PLUGIN_PATH=/opt/gstreamer/lib/gstreamer-0.10
export PATH=/opt/gstreamer/bin:$PATH
cat /dev/zero > /dev/fb2 2> /dev/null
The above command assumes that gstreamer is installed in /opt/gstreamer directory.

gst-launch -v filesrc location=sample.m4v ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite sync=false
PAL:
gst-launch -v filesrc location=sample.m4v ! TIViddec2 codecName=mpeg4dec engineName=codecServer ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=composite sync=false

gst-launch filesrc location=sample.mp3 ! mp3parse ! ffdec_mp3 ! alsasink
AAC pipeline:
gst-launch filesrc location=sample.aac ! faad ! alsasink
Decode .AVI Files
The following pipeline assumes you have an AVI file with MPEG-4 Video and MP1L2 or MP3 Audio. Note that not all MPEG-4 video streams can be played using the DM355 MPEG-4 decoder -- make sure the MPEG-4 stream was encoded with the DM355 MPEG-4 encoder or another compatible encoder.
gst-launch -v filesrc location=sample.avi ! avidemux name=demux demux.audio_00 ! queue max-size-buffers=8000 max-size-time=0 max-size-bytes=0 ! mad ! alsasink demux.video_00 ! queue ! TIViddec2 ! TIDmaiVideoSink videoStd=D1_NTSC videoOutput=composite

Network Streaming
This section gives example where EVM acts as streaming server,which captures,encodes and transmit via udp. Host PC can be used as client to decode.
MPEG-4 Encode/Stream/Decode:

gst-launch -v v4l2src always-copy=FALSE ! TIVidenc1 codecName=mpeg4enc engineName=encode contiguousInputFrame=TRUE ! rtpmp4vpay pt=96 ! udpsink host=<HOST IP ADDRESS> port=5000
When the pipeline starts to run,you'll see something that looks like this:
/GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps = application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP4V-ES,profile-level-id=(string)1,config=(string)000001010000012000845d4c28b421e0a21f,payload=(int)96,ssrc=(guint)3412089386,clock-base=(guint)945410414,seqnum-base=(guint)27711
Make a note of caps="application/x-rtp,media=(string)video ................" string and pass this string in client below
A simple RTP client to decode MPEG-4 and display on HOST machine
gst-launch -v udpsrc port=5000 caps="<PASS_CAPS_FROM_SERVER>" ! rtpmp4vdepay ! ffdec_mpeg4 ! xvimagesink
For sending and receiving MPEG-4 with DM355 EVM you can use these 2 pipelines :
RTP server side :
gst-launch -v videotestsrc ! TIVidenc1 codecName=mpeg4enc engineName=encode ! rtpmp4vpay send-config=true ! udpsink host=<HOST IP ADDRESS> port=5000
Don't forget to set the "send-config" property to true
RTP client side :
gst-launch -v udpsrc port=5000 caps="application/x-rtp,config=(string)000001010000012000845d4c285020f0a21f,ssrc=(guint)3319524202,clock-base=(guint)4012564513,seqnum-base=(guint)25833" ! rtpmp4vdepay ! TIViddec2 codecName=mpeg4dec engineName=decode ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=composite sync=false
Note that client should be started before server
DM357
This section covers pipelines for common use cases for the DM357 processor.
Environment Requirements
Before executing the pipeline you need to set couple of environment variables,load kernel modules and activate video planes as follows:
cd /opt/gstreamer_demo/dm357/
./loadmodules.sh
export GST_REGISTRY=/tmp/gst_registry.bin
export LD_LIBRARY_PATH=/opt/gstreamer/lib
export GST_PLUGIN_PATH=/opt/gstreamer/lib/gstreamer-0.10
export PATH=/opt/gstreamer/bin:$PATH
cat /dev/zero > /dev/fb2 2> /dev/null
The above command assumes that gstreamer is installed in /opt/gstreamer directory.
Notes on DM357 Performance:There is a known issue on DM357 where there are intermittent freezes in video and audio playback in some cases. If you experience this,nicing your gst-launch command to 15 as follows may resolve the issue:
nice -n 15 gst-launch .... (rest of gst-launch command)
