  • FFPLAY shows video, but FFMPEG just shows black

    22 mai 2017, par ahenshaw

    I’m trying to record video/audio from a VIDBOX device using ffmpeg. Using Windows 10 and ffmpeg version N-86129-g1e8daf3, I can see and hear the video/audio fine when I execute

    ffplay -f dshow -i video="VIDBOX NW07":audio="Microphone (VIDBOX NW07)"

    but, I only record a black screen (and the correct audio) when I execute

    ffmpeg -f dshow -i video="VIDBOX NW07":audio="Microphone (VIDBOX NW07)" -c:v libx264 out.mp4

    What could be causing this to work in ffplay but not ffmpeg ?

  • How do I keep black areas black with ffmpeg ?

    20 avril 2017, par P. Dee

    When encoding GoPro videos with ffmpeg using

    ffmpeg -i Goprovideo.mp4 Goprovideo-out.mp4

    I noticed that the videos do not only get much smaller, but also in some cases do black areas lose intensity. So what was black is now grey. Not to an extreme, but slightly noticable.

    How do I keep black areas black with ffmpeg ?

  • FFmpeg / Avconv video playback problems - black or green tint

    21 octobre 2014, par scottpaterson

    I am using FFmpeg / Avconv to convert a raw video file to a MP4 or AVI. Both FFmpeg and Avconv have the same problem.

    • The output video, both MP4 or AVI, play 100% percent perfect on Linux Mint in the default video player.

    • On Windows in WMP the MP4 plays, but the video is black, and the AVI plays and shows video but it has a green tint. On Windows in Quicktime both formats video is black.

    Here is the command I am using :

     avconv -i /home/scott/Desktop/out.wav -f rawvideo -pix_fmt rgb32 -s:v 540x240 -i 
    
 /home/scott/Desktop/out.raw -c:v libx264 -strict -2 -preset ultrafast -b:v 160k  
    
 /home/scott/Dropbox/code/out.avi

    • I have spent a lot of time messing with the -pix_fmt and trying different pixel format, so far rgb32 returns the best results.

    • I have also tried -sws_flags options such as lanczos+accurate_rnd - but this did not help.

    How can I get this to play the same in all video players ?

    Thanks !
