I am trying to play a .ts file with Gstreamer-1.0 as well as gst-omx have been successfully installed .
Try to play ts video using below command line format but failed to play.
test#test-Gardenia:~/Videos$ gst-launch-1.0 -v filesrc location= mpeg2.ts ! tsdemux ! mpegvideoparse ! omxmpeg2dec ! videoconvert ! ximagesink

Tried below command also but not did not work.

WARNING: erroneous pipeline: could not link mpegtsparse2-0 to omxmpeg2videodec-omxmpeg2dec0
Can any one help me how to play .ts file with mpeg2 codec format using gstreamer

when I am trying to send a video sample that I downloaded from the internet, which has both AAC and H-264 codecs the following command is working fine. but when I generated the mp4 file using OpenCV which has only the H-264 codec and no AAC as there was no audio it is giving me the following error.
command :
gst-launch-1.0 -v filesrc location="YourAudioVideo.mp4" ! qtdemux name=demux ! queue ! h264parse ! video/x-h264,stream-format=avc,alignment=au ! kvssink name=sink stream-name="audio-video-file" access-key="YourAccessKeyId" secret-key="YourSecretAccessKey" streaming-type=offline demux. ! queue ! aacparse ! sink.
error log :

You obviously remove the AAC part in your pipeline then:
gst-launch-1.0 -v filesrc location="YourAudioVideo.mp4" ! qtdemux name=demux ! queue ! h264parse ! video/x-h264,stream-format=avc,alignment=au ! kvssink name=sink stream-name="audio-video-file" access-key="YourAccessKeyId" secret-key="YourSecretAccessKey" streaming-type=offline
i am trying to play sequence of image(.jpeg) from my local folder to play as h264 video in VLC player through local host connection.
I am using Gstreamer lib to stream support and i am using from test-launch.c from github samples
OS : Linux 18.04
Gstremer ver: 1.14.2 Building from source using Cerbero
Following command is used to set the parser
multifilesrc location=/home/user/Downloads/gen/img.%4d.jpeg loop=true caps=image/jpeg,framerate=10/1 ! jpegdec ! x264enc ! h264parse ! rtph264pay name=pay0 pt=96
but no streaming happening insted i can see a error like below
(Gstremer_img2vid2:21273): GStreamer-CRITICAL **: 15:57:21.547: gst_bin_get_by_name: assertion 'GST_IS_BIN (bin)' failed
0:01:26.143446201 21273 0x55555592b850 ERROR rtspclient rtsp-client.c:3105:handle_setup_request: client 0x5555559d5260: no control in path '/test'
Any help will be appreciated thanks
You may have to provide size of the frames for jpeg decoding (here using 640x480):
test-launch "multifilesrc location=/home/user/Downloads/gen/img.%4d.jpeg loop=true ! image/jpeg,width=640,height=480,framerate=10/1 ! jpegdec ! x264enc insert-vui=1 ! h264parse config-interval=1 ! rtph264pay name=pay0"
Should be ok for receiving on localhost using vlc:
cvlc rtsp://127.0.0.1:8554/test
Hy i tried to play a doorbird live audio stream via gstreamer gst-launch.
I found a code snipped in an fhem server script.
It should be possible with the command gst-launch-1.0 filesrc location=<http://12.0.0.231/bha-api/audio-receive.cgi user=xxxx passwd=xxxx> ! wavparse ! audioconvert ! lame ! filesink location=a.mp3
But i get following error: lame not found. if i change lame to lame lamemp3enc i get the error file not found http://12.0.0.231/bha-api/audio-receive.cgi
What do i wrong?
This is my pipeline:
gst-launch-1.0 rtspsrc location='<my_rtsp>'
! rtph264depay
! h264parse
! splitmuxsink location=/<my_path>/video%02d.mp4 max-size-time=60000000000
Every ~60 files (59-61) pipeline crash and i see this:
**
ERROR:gstsplitmuxsink.c:805:handle_gathered_gop: assertion failed: (queued_bytes >= splitmux->mux_start_bytes)
Aborted
is it possible to correct this error?
(I use GStreamer 1.8.0)
First, I have read the following thread, but I want to harness the webcam hardware JPEG compression as opposed to software h264 compression.
Second, I tested the following pipeline and it works:
gst-launch-1.0 -v v4l2src device=/dev/video1 ! 'image/jpeg,width=640,height=480,videorate=8/1' ! jpegdec ! xvimagesink
Then I tried similar pipeline but with udpsink at the end:
gst-launch-1.0 -v v4l2src device=/dev/video1 ! 'image/jpeg,width=640,height=480,videorate=8/1' ! rtpjpegpay ! udpsink host=127.0.0.1 port=1234
Then I tried to play this stream:
gst-launch-1.0 -v udpsrc port=1234 ! "application/x-rtp, payload=96" ! rtpjpegdepay ! jpegdec ! xvimagesink
And it failed with the following errors:
/GstPipeline:pipeline0/GstJpegDec:jpegdec0.GstPad:sink: caps =
image/jpeg, framerate=(fraction)0/1, width=(int)640, height=(int)480
** (gst-launch-1.0:10761): CRITICAL **: gst_adapter_push: assertion 'GST_IS_BUFFER (buf)' failed
** (gst-launch-1.0:10761): CRITICAL **: gst_jpeg_dec_fill_input_buffer: assertion 'dec->current_frame_map.data

Any suggestions?
