  • Processing video using ffmpeg and saving the output to MongoDB

    10 juillet 2013, par kheya

    I have user uploaded video saved in a folder (can be in any of 5/6 formats)
    I have 2 needs.

    • Extract 3 frame images (that I will show to user for possible thumbnail
    • Convert the video to one or more other formats (flv + WebM)

    I am planning to use FFMPEG command line tool.

    How do I write the output from FFMPEG to MongoDB gridFS ?

    Is it even possible or I have to write the files to folder first & then save to gridFS ?

    Thanks

  • Add 2 pictures to video with durations ? [duplicate]

    24 juin 2013, par jesper

    This question already has an answer here :

    I am trying to add 2 different images into a video with ffmpeg.

    image1.jpg should show the first 10 seconds of the movie and youtubeLOL.png should show the next 6 minutes of the video.

    So the command should tell us also to repeat the pictures to get a length for 6 minutes and 10 seconds. How can i do this ? I have tried this :

    (It's not even working)

     passthru("ffmpeg -f image2 -loop 1 -vframes 100 -i /home/psafari/public_html/youtube_images/movie_" . $id . ".jpg -vcodec mpeg4 /home/psafari/public_html/youtube_videos/movie_" . time().".avi");

    Here is output :

  • ffmpeg encoding plays very fast. Audio.mp4 and Video.mp4 work, but both together don't

    25 février 2013, par Peter.O

    In both steps 3 and 4 below, the .mp4 plays normally. However, although I've used what seems to be the same settings in the last step (audio + video), that step does not work. The video plays more than 10 times too fast... also the audio does not play.

    The ffmpeg messages for step 5 show that it has included audio.

    Output #0, mp3, to '/tmp/test.mp4':
    
    Stream #0.0: Video: libx264, yuv420p, 720x480, q=2-31, 90k tbn, 23.98 tbc
    
    Stream #0.1: Audio: libmp3lame, 48000 Hz, stereo, s16, 128 kb/s

    Subsequently running ffmpeg -i shows no trace of the audio, but it does report on the video... What have I missed, to get it muxed properly ?...

    #!/bin/bash
    

    
# 1. create Audio 
    
wine avs2pipe.exe audio "$src_avs" >"$temp_pcm"
    

    
# 2. create Video 
    
wine avs2yuv.exe "$src_avs" - |
    
  x264 --stdin y4m --output "$temp_h264" - 2>/dev/null
    

    
# 3. This works.  (audio only)
    
# encode `audio.mp4 
    
ffmpeg -acodec pcm_s16le -f u16le -ac 2 -ar 48000 -i "$temp_pcm" \
    
       -acodec libmp3lame -f mp3 -ar 48000 -ab 128k  -y "$audio_mp4"
    

    
# 4. This works.  (video only)
    
# encode `video.mp4 
    
ffmpeg -i "$temp_h264" \
    
       -vcodec copy -y "$video_mp4"
    

    
# 5. This DOES NOT work!  It plays very fast.
    
# encode `final.mp4' 
    
ffmpeg -acodec pcm_s16le  -f u16le  -ac 2 -ar 48000  -i "$temp_pcm" \
    
       -i "$temp_h264" \
    
       -acodec libmp3lame -f mp3 -ar 48000 -ab 128k \
    
       -vcodec copy \
    
       -y "$final_mp4"
