• FFmpeg : Invalid data found when processing input after created a video slideshow from images

  8 décembre 2014, par David Zhuang

  FFmpeg provides some examples of making slideshow from image(s) :

  https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

  So I ’ve tried this command :

  ffmpeg -loop 1 -t 10 -framerate 24 -i '1.png' -c:v libx264 -crf 36 -vf scale=640:360 -pix_fmt yuv420p -shortest 2.mp4

  It is a success generating a MP4 file. Also there’s no problem remuxing it into FLV.

  FFmpeg gave no no error when I mux the video stream into .h264 .

  But when I tried to process this file further, ffmpeg gave me this error :

  $ffmpeg -i 2.h264

• Upgrade FFmpeg using GIT

  5 février 2014, par xirukitepe

  Hi I want to verify if my FFMpeg version is not updated.

  Here's the output upon running this command : ffmpeg -version

  ffmpeg version git-2013-04-05-9a8f1e7 Copyright (c) 2000-2013 the FFmpeg developers
  
    built on Apr  5 2013 18:38:36 with gcc 4.6 (Ubuntu/Linaro 4.6.3-1ubuntu5)
  
    configuration: --enable-gpl --enable-libass --enable-libfaac --enable-libfdk-aac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libspeex --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-nonfree --enable-version3

  I am not super familiar when FFmpeg is compiled and installed via GIT.

  I just followed the Ubuntu Compilation Guide by FFmpeg.

  And how to verify if it is not the latest ? Thanks in advance.

  PS

  The remote is : git://source.ffmpeg.org/ffmpeg.git

  I have this code
for %%t in ("input\*.*") DO ffmpeg -y -i "%%t" -i 1.mp4 -filter_complex "[0:v]scale=1280x720[v1];[1:v]scale=1280x720[v2];[v1][v2]overlay=shortest=1:enable='lt(mod(t,6),4)*gte(t,1.5)':x=0:y=0, [0:a][1:a]overlay=shortest=1:enable='lt(mod(t,6),4)*gte(t,1.5)" -vcodec libx264 -pix_fmt yuv420p -r 30 -g 60 -b:v 1000k -acodec libmp3lame -b:a 128k -ar 44100 -metadata title="" -metadata artist="" -metadata album_artist="" -metadata album="" -metadata date="" -metadata track="" -metadata genre="" -metadata publisher="" -metadata encoded_by="" -metadata copyright="" -metadata composer="" -metadata performer="" -metadata TIT1="" -metadata TIT3="" -metadata disc="" -metadata TKEY="" -metadata TBPM="" -metadata language="eng" -metadata encoder="" -threads 0 "%OUTPUT%\%%~nt.mp4"
