  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    10 juillet 2014, par woj_jas

    I’m trying to convert mkv file to webm by ffmpeg.
    I’m using :

    My problem is that I get Error :

    Can somebody help me fix that ?

  • ffmpeg - how to merge multiple audio with time offset into a video ? [on hold]

    29 mai 2017, par Xi Xiao

    I want to use FFMPEG to merege multiple audios and one video.

    Materials are :

    1. two short audio clips (short-clip-1.3gp, short-clip-2.3gp),
    2. one video clip (1.mp4) with sound,
    3. and one audio clip (1.mp3) that has same duration as the video clip.

    Requirement is :

    1. Remove video clip’s sound
    2. add 1.mp3
    3. add short-clip-1.3gp at 0 sec timetamp, short-clip-2.3gp at 10 sec timestamp.

    The requirement is depicted like below.

    <—short-clip-1.3gp time duration—> <—short-clip-2.3gp time duration—>

    <-------------------------------------- 1.mp3 ----------------------------------------------------->

    <-------------------------------------- 1.mp4 ----------------------------------------------------->

    The command I use is as below, but it does not work as expected.

    ffmpeg -i 1.mp4 -i 1.3gp -itsoffset 00:00:10 -i 2.3gp -i 1.mp3 -map 0:v -map 1:a -map 2:a -map 3:a -c:v copy -c:a copy result.mp4

    Any hint is appreciated !

    Changed Paths :
     Modify /vp9/encoder/vp9_rdopt.c



    Add best_rd breakout in intra4x4 RD loop.

    Encoding time of first 50 frames of bus (speed 0) @ 1500kbps goes from
    1min5.4 to 1min4.0, i.e. 2.2% faster overall.
