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!
