I am running this script to view cameras on network:
gst-launch udpsrc port=1234 ! "application/x-rtp, payload=127" ! rtph264depay ! ffdec_h264 ! xvimagesink sync=false
I am getting this error:
WARNING: erroneous pipeline: no element "ffdec_h264"
I am getting error with ffdec_h264. I have all the packages from g-streamer but I don't know which one I am missing.
when I run gst-inspect | grep 264
I get this output:
h264parse: legacyh264parse: H264Parse

rtp: rtph264pay: RTP H264 payloader
rtp: rtph264depay: RTP H264 depayloader
Which shows I don't have this ffdec_h264
which package I am missing?
This might depend on your OS/distribution and GStreamer version.
Over here (Debian jessie, GStreamer 0.10.36) gst-inspect ffdec_h264 gives the following output:
Factory Details:
Long name: FFmpeg H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 decoder
Class: Codec/Decoder/Video
Description: FFmpeg h264 decoder
Author(s): Wim Taymans <wim.taymans#gmail.com>, Ronald Bultje <rbultje#ronald.bitfreak.net>, Edwar$
Rank: primary (256)
Plugin Details:
Name: ffmpeg
Description: All FFmpeg codecs and formats (system install)
Filename: /usr/lib/x86_64-linux-gnu/gstreamer-0.10/libgstffmpeg.so
Version: 0.10.13
License: GPL
Source module: gst-ffmpeg
Binary package: FFmpeg
Origin URL: http://ffmpeg.org/
So on my system, ffdec_h264 is in the gst-ffmpeg module (which was installed using apt-get install gstreamer0.10-ffmpeg).
You have to enter this command and have an idea what h264 decoder you have with gstreamer, in other words what Gstreamer is calling it.
gst-inspect | grep "h264"

Recently, I see this error very often. Does anyone know what the error is and how to fix ? Please check full ffmpeg output here ( I already update openssl latest version from yum )

This error normally indicates a bug in the program calling OpenSSL. When an application using OpenSSL attempts to write application data to an SSL/TLS connection using the "SSL_write" function it may be unable to complete the write in one go (for example because the underlying network buffers are full). In this case a recoverable "retry" error occurs. The application is supposed to retry the write with exactly the same data as last time. If the calling application retries the write with different data then you get the "bad write retry" message (a fatal error). As to how to fix it that unfortunately depends on identifying the bug in the calling application and ensuring that retries are only ever performed with exactly the same data.
I'm looking the TF Lite Android App
Which can be found on GIT: https://github.com/tensorflow/tensorflow/tree/master/tensorflow/contrib/lite/java/demo
How can I compile the tensorflow lite framework to use the optimized "atom" cpu type?
Is it possible to compile it on a MAC os with the CPU optimizations for the "atom" cpu?
I want to run the app on an Android device (SDK 22) with an "Intel Atom" Processor.
When I run the application without any changes through Android Studio the rate was about 1200ms per frame.
Compering the same APK installed on my Galaxy S9 (arm - snapdragon processor) was about 30ms per frame.
In the "build.gradle" there is this section:
dependencies {
...
compile 'org.tensorflow:tensorflow-lite:0.0.0-nightly'
...
}
So it's seems that it's downloading the framework,
How can I compile it locally with the CPU optimization and set the app to use it instead of downloading the non optimized nightly version?
I tried to run this tutorial :
Installing TensorFlow from Sources with the cpu flags but not sure exactly how it's helping me with the Android scenario..
Assuming that your Atom device is x86, use the --fat_apk_cpu flag to specify the x86 ABI:
$ bazel build -c opt --cxxopt='--std=c++11' \
--fat_apk_cpu=x86 \
//tensorflow/contrib/lite/java/demo/app/src/main:TfLiteCameraDemo
Switch x86 with x86_64 if you're building for a 64-bit device.
The built APK, available at bazel-bin/tensorflow/contrib/lite/java/demo/app/src/main/TfLiteCameraDemo.apk, will contain the x86 .so file:
$ zipinfo bazel-bin/tensorflow/contrib/lite/java/demo/app/src/main/TfLiteCameraDemo.apk | grep lib
-rw---- 2.0 fat 1434712 b- defN 80-Jan-01 00:00 lib/x86/libtensorflowlite_jni.so
If your device is connected, you can use bazel mobile-install instead of bazel build to directly install the app:
$ bazel mobile-install -c opt --cxxopt='--std=c++11' \
--fat_apk_cpu=x86 \
--start_app \
//tensorflow/contrib/lite/java/demo/app/src/main:TfLiteCameraDemo
I'm trying to stream video of camera and audio of mic using Gstreamer.
Use Odroid C1+ as a server and PC as a client.
When I use lan cable, it's perfact. But it's performance significantly decrease when I use WiFi.
I used
$ gst-launch-1.0 v4l2src ! gdppay ! tcpserversink host=localhost port=5000 alsasrc device="hw:1,0" ! gdppay ! tcpserversink host=localhost port=6000
$ gst-launch-1.0 tcpclientsrc host=localhost port=5000 ! gdpdepay ! autovideosink sync=false tcpclientsrc host=localhost port=6000 ! gdpdepay ! autoaudiosink sync=false
and
$ gst-launch-1.0 v4l2src ! videoconvert ! x264enc tune=zerolatency ! rtph264pay ! gdppay ! tcpserversink host=localhost port=5000 sync=false alsasrc device='hw:0,0' ! gdppay ! tcpserversink host=localhost port=6000 sync=false
$ gst-launch-1.0 tcpclientsrc host=localhost port=5000 ! gdpdepay ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false tcpclientsrc host=localhost port=6000 ! gdpdepay ! autoaudiosink sync=false
How can I maximize the performance of the streaming of Gstreamer,
and also synchronize video and audio?

You might be using the wrong driver for your webcam.
Use the lsusb command to identify your webcam. Then find out what driver you need to get it working. You can find out more information about this by reading the Webcam Arch Wiki Page
