  • 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"
  • 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 :
