  • Is it possible to force a key frame 2 seconds after the time of the last key frame by using FFMPEG ?

    13 octobre 2015, par Alexandr

    I know that prev_forced_t returns time of the last forced key frame. But I need something that return time of the last key frame (not forced but any).

    This parameter will work only with forced frames :
    -force_key_frames "expr:gte(t,prev_forced_t+2)"

    I need something like :
    -force_key_frames "expr:gte(t,${LAST_KEY_FRAME_T}+2)"

  • When merging video and audio, converting audio to AAC, sound is missed at the end 3 seconds

    10 octobre 2013, par profuel

    I have to build video from images and some audio clip.
    Audio is much longer, so I have to mute last 5 seconds of audio track, cutting to video length.
    My issue is that adding AAC encoding to audio removes last 2-5 seconds of audio in resulted video.

    Here are my command lines :

    ffmpeg -i sound.mp3 -i video.mp4 -shortest out.mp4 -> results in correct audio in result video with played audio over 100% of movie

    ffmpeg -i sound.mp3 -i video.mp4 -acodec aac -ab 160000 -strict experimental -shortest out.mp4 -> not correct audio, gets crop at end of video for 2-5 seconds


    The problem appears for me both on Windows and on CentOS 6.4, no matter which version of ffmpeg is used.
