Compile The Latest ffplay From Source

Compile latest version of ffplay from source

Note that this script doesn't overwrite the existing ffmpeg installation:
https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

The gotcha in the above guide is the SDL-devel package without which ffplay will not build.

#! /bin/bash
yum install autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial nasm pkgconfig zlib-devel SDL-devel


mkdir ~/ffmpeg_sources


cd ~/ffmpeg_sources
git clone --depth 1 git://github.com/yasm/yasm.git
cd yasm
autoreconf -fiv
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
make distclean


cd ~/ffmpeg_sources
git clone --depth 1 git://git.videolan.org/x264
cd x264
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
make
make install
make distclean


cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make
make install


cd ~/ffmpeg_sources
git clone --depth 1 git://source.ffmpeg.org/ffmpeg
cd ffmpeg
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --extra-cflags="-I$HOME/ffmpeg_build/include" --extra-ldflags="-L$HOME/ffmpeg_build/lib" --bindir="$HOME/bin" --pkg-config-flags="--static" --enable-gpl --enable-libx264 --enable-libx265 --enable-ffplay
make
make install


cd /usr/lib
ln -s /home/username/bin/ffplay fffplay

Play Video With Low Latency Using ffplay

This is the fastest I can make ffplay:

$ ffplay -threads 2 -flags low_delay -fflags nobuffer -rtbufsize 32768 -fast -probesize 800000 -analyzeduration 800000 -ss 1 -framerate 50 udp://224.0.1.6:2006


Play Video With ffmpeg

This also quite fast, just to show that you can play video directly with ffmpeg using SDL output:

$ ffmpeg -i udp://224.0.1.6:2006 -f sdl -


Play Video With gstreamer

Just because it also pertains to playing video, here are a couple tricks with gstreamer:

$ gst-launch -v playbin uri=udp://224.0.1.6:2006

First try a video test pattern though:

$ gst-launch-0.10 videotestsrc ! ffmpegcolorspace ! autovideosink

If the test pattern doesn't work, then there is no point in continuing - you got to fix it.

La Voila!

    When I want to play video with FFMPEG, I get this error:

    Could you please post your exact command?

    I am thinking that you either have a spelling mistake in the command, or the SDL package is not installed.

PCB Mill

PCB Mill Kit My latest toy is a small PCB Mill, a CNC 3018 Pro, there are many available from Ali Express for the enormous sum of 285 Dirhams or so, which is about 70 Euro.  I thought that even if it didn't work at all, it would not be a big loss. Assembled CNC 3018 Kit It will help if you have a little previous workshop experience, but these machines are so simple and relatively slow moving, that any radio-geek can safely experiment. Carving With a V-bit in a Puddle of Oil Of course I can have boards made in China by Dirty PCBs , but what is the fun in that? The problem with making PCB antennas, is that you need to experiment to change the design 1 mm this way or that, to tune it just so and just such and having to wait 2 weeks for each experiment doesn't work.  A few hours playing with a router is more practical. It turned out to be a pretty nice little kit, made from aluminium and 1/4 inch Bakelite (paper reinforced phenol formaldehyde).  This Pre...

OpenEMS with Octave and SciLAB

I wanted to do some advanced RF antenna development work and needed an electromagnetic field solver that is a bit more up to date than NEC2 .  Commercial solvers from Matlab , Ansys and others are hideously expensive (in the order of $20,000 to $50,000) and do not fit in the wallet of a hobbyist or a small consulting company.  Recently, openEMS became available and it fills the niche with a capable free tool.  In general, openEMS is a solver - a Finite-Difference Time-Domain (FDTD) numerical engine.  You interact with it through Octave , which is almost identical to Matlab .  You can watch a good video by Thorsten Liebig here: https://www.youtube.com/watch?app=desktop&v=ThMLf0d5gaE   Getting it to work is a little painful, but it is free, so bear with it - then save a backup clone, or a zipped copy of the whole virtual machine directory and NEVER update it, to ensure that it keeps going and doesn't get broken by future updates, right when you are ...

Yagi Antenna for 900 MHz ISM Band

I like tinkering with wire antenna designs, since they are simple and cheap to make.  Mr Yagi invented his antenna about 100 years ago, but there are still some things left to learn about it. 900 MHz ISM Band Yagi The 900 MHz ISM band ranges from 902 to 928 MHz.  Covering the whole band with a single Yagi antenna is difficult, since they are inherently narrow band devices.  Consequently some tweaking is required and the result below is a desensitized design that can be built and replicated quite easily, but you need a network analyzer - "To Measure, is to Know!" A Yagi generally consists of a Reflector, Radiator and one or more Director elements, arranged on a boom.  For a small Yagi, a wooden ruler works a treat, since one can easily mark the position of the wires.  The wire elements are fastened to the bottom of the ruler with hot glue.  The wire elements are  made from straightened out jumbo size paper clips.  The balun, is tw...
