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)

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

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
While executing the following command,
gst-launch-1.0 filesrc location=Wildlife.wmv ! decodebin ! queue ! ffmpegcolorspace ! autovideosink dec. ! queue ! audioconvert ! audioresample ! autoaudiosink
I Get the error as follows.
ERROR GST_PIPELINE grammar.y:716:priv_gst_parse_yyparse: no element "ffmpegcolorspace"

What is the problem here?
A few things:
In gstreamer-1.0, ffmpegcolorspace was renamed to videoconvert.
You need to give your decodebin the name you want to refer to it later. Add name=dec to be able to refer to it when linking the audio branch.
Also, you might want to consider just using playbin if you just need playback. It will assemble the pipeline for you and will support multiple formats automatically.
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.

Can any one help me how to play .ts file with mpeg2 codec format using gstreamer
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?
