• Error installing ffmpeg on Ubuntu 8.04 JeOS with Speex

  15 novembre 2011, par tubbo

  I'm having an issue installing ffmpeg with Speex support on Ubuntu 8.04 JeOS. After some wandering around in dependency hell I managed to secure the proper libspeex and ffmpeg versions, and it ./configured properly, but when I try to run make && make install, it fails with the following error :

  ffmpeg.c: In function ‘opt_recording_timestamp’:
  
  ffmpeg.c:3080: warning: dereferencing type-punned pointer will break strict-aliasing rules
  
  ffmpeg.c: In function ‘opt_input_file’:

  I'm a complete noob to ffmpeg and speex, except for using the codec on Ventrilo back in the day. Can someone shed some light as to why this is happening ?

• FFMPEG : ‘PIX_FMT_BGR24’ was not declared in this scope

  9 août 2016, par msz

  I am building a simple decoding application using FFMPEG API. I know there are solutions available in OpenCV but for specific reason I am refraining myself from using that. Since I am very new to FFMPEG (and to this community as well), I would like to know if there is any mistake that I might have done while building FFMPEG.

  Compiler : I am using gcc 5.3.0 for compilation and building.

  Following are the steps that I followed :

  1. I have build FFMPEG library using following configuration :

     ./configure —prefix=/home/dep/ffmpeg/install/ —pkg-config-flags=—static —enable-gpl —disable-yasm

  2. My compiling command is for the application :

     g++ -std=c++11 -I/home/dep/ffmpeg/install/include/ Queue.cpp Image.cpp CaptureFFMPEGFrame.cpp Object.cpp main.cpp -o main -L/home/dep/ffmpeg/install/lib -lavutil -lavcodec -lavformat -lavdevice -lavfilter -lswscale -lswresample -lpostproc -lpthread -lz -lrt -llzma -lbz2

  The error I am facing is :

  CaptureFFMPEGFrame.cpp:203:169: error: ‘PIX_FMT_BGR24’ was not declared in this scope
  
       mpFrameSwsContext = sws_getContext(mpAVCodecContext->width, mpAVCodecContext->height, mpAVCodecContext->pix_fmt, mpAVCodecContext->width, mpAVCodecContext->height, PIX_FMT_BGR24, SWS_BICUBIC, NULL, NULL, NULL)

  My effort and understanding :

  1. From my understanding, libavutil/pixfmt.h contains pixel formats which I included along with other includes and the error persists. You can also see libraries I have included along with my application.

  2. Since my program is cpp code, therefore my headers are already included using extern "C", i.e. #include "libavcodec/avcodec.h"

  Anything I might have missed ?

  Many thanks.
