• FFmpeg Ubuntu linker error

  29 mars 2016, par CodeDezk

  I am trying to decode audio using ffmpeg lib and c++ from Ubuntu 12.04. I am following the code here https://0xdeafc0de.wordpress.com/2013/12/19/ffmpeg-audio-playback-sample/

  Below is the command used to compile the code

  g++ -std=c++11 decode_play_audio.cpp -I/home/codeDev/ffmpeg_sources/build_Mar-10-2016/include -L/home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib  -lavcodec -lavformat -lavutil

  But getting the compile error as below,

  I have build latest ffmpeg 3.0 and located at /home/codeDev/ffmpeg_sources/build_Mar-10-2016/

  And I can see all the libs located at /home/codeDev/ffmpeg_sources/build_Mar-10-2016/lib

    libavcodec.a
  
    libavfilter.a
  
    libavutil.a
  
    libswresample.a
  
    pkgconfig
  
    libavdevice.a
  
    libavformat.a
  
    libpostproc.a
  
    libswscale.a

  I am using ClipBucket. I have set up ffmpeg environment, I can convert avi, wmv files to FLV video files without any problem, but now I am trying to convert a FLV video file to FLV video file with different video quality. However, there is error in the conversion. Can someone help me please ?

• Carrierwave and FFMPEG saving to 2 destinations - Rails, Fog, S3

  20 avril 2013, par dodgerogers747

  I have a video model, which uses Carrierwave, Fog, FFMPEG and S3 to handle video files. I have a method in my video model that takes a screenshot before the video is saved to S3. Both Video and screenshot are saved to S3 using 2 Carrierwave Uploader classes, Image_uploader and video_uploader with the video being saved to the Video.file column and screenshot saved at the Video.screenshot.

  This all works as intended, however, FFMPEG also saves a copy of the screenshot to the rails filesystem, "Rails.root/file_is_saved_here". For now I have FFMPEG saving this file into the Rails.root/public/uploads folder along with the tmp files created by Carrierwave.

  How can I get one screenshot saved to S3 without the second being saved on the filesystem ?
