PDrAW is a viewer for videos produced by Parrot Drones (Bebop, Bebop2, Disco, etc.).
It supports both streamed (RTP) and recorded (MP4) videos.

• Linux PC
• MacOS X
• Android (4.2 minimum)
• iOS (8.0 minimum)
• RaspberryPi

• Demuxing
  • Record demuxer
    • MP4 file format (ISO/IEC 14496-12, ISO Base Media File Format / ISO/IEC 14496-14, MP4 File Format)
  • Stream demuxer
    • RTP/AVP/UDP streams (RFC 3550, RFC 3551)
    • Unicast or multicast
    • RTSP protocol (RFC 2326)
    • Opening directly from a SDP (RFC 4566) document
  • Playback control
    • Play/pause
    • Seeking (except for live streams)
    • Playback speed control (except for live streams)
    • Negative speeds for playing backward (except for live streams)
    • Frame-by-frame forward and backward (except for live streams)
  • Support of Parrot session and frame metadata
• Decoding
  • H.264 video decoding (ITU-T H.264 / ISO/IEC 14496-10), baseline, main and high profiles
  • Frame output API for application-side processing on the video
• Rendering
  • OpenGL ES 2.0 video rendering
  • HMD distorsion correction
    • Support for Parrot Cockpitglasses 1 & 2
    • Device settings for screen density and mechanical margin
    • User settings for video scale, placement and IPD
  • HUD: real-time flight instruments
  • Headtracking
    • Uses Google VR SDK (Android only)
    • Fake headtracking on Linux/MacOS app using the mouse

PDrAW is mainly libpdraw, with platform-specific applications built on top.

Available applications built on top of libpdraw:

• pdraw_linux: PC-Linux application using SDL2 for windowed display
• pdraw_macos: MacOS X application using SDL2 for windowed display
• pdraw_raspi: RaspberryPi application using EGL/dispmanx for display
• pdraw_android: Android application
• pdraw_ios: iOS application

Available APIs for libpdraw are:

• C
• C++
• Java for Android (through JNI)
• Python (using SWIG)

TBD

Required packages:

$ sudo apt-get install build-essential yasm cmake libtool libc6 libc6-dev
unzip wget freeglut3-dev libglfw3-dev libsdl2-dev libjson-c-dev
libcurl4-gnutls-dev libavahi-client-dev

Get the sources:

$ repo init -u https://github.com/Akaaba/pdraw_manifest.git
$ repo sync

Compiling for a Linux PC:

$ ./build.sh -p pdraw-linux -t build -j

To use hardware H.264 decoding (NVDec) with NVidia GPUs, the following packages are also required:

$ sudo apt-get install libnuma1 libnuma-dev nvidia-cuda-toolkit

An updated version of CUDA Toolkit may be necessary: https://developer.nvidia.com/cuda-downloads

Enable cuvid in the build configuration

$ ./build.sh -p pdraw-linux -t xconfig
    -> search for "cuvid" and enable
$ ./build.sh -p pdraw-linux -t build -j

Note: FFmpeg with cuvid uses non-free software; PDrAW cannot be distributed with cuvid enabled.
