  • ffmpeg - How do I compress a .mov file with partial transparency, while keeping the partial transparency ?

    4 juin 2020, par Nick

    The codec I use is QuickTime Animation. I tried the following :

    



    ffmpeg -i Animation.mov -c:v libvpx-vp9 out.webm

    



    That compressed my 420MB source file to a nice 1.5MB but my partial transparency was lost. The Animation is a minute long, while only 12 seconds are actually animated, the rest is a still image. Anyone got some Ideas ? I'm looking for a target size of roughly 10MB.

    



    Edit : output format is irrelevant to me.

    



    Edit 2 : The method I used actually does support partial transparency. VLC is just unable to display it correctly.

    


  • FFMPEG two black frames in the beginning when converting mp4 aac to mov pcm [closed]

    12 octobre 2023, par Veikka

    I'm trying to convert mp4 h265 aac file to mov 265 pcm16sle file using ffmpeg withoat touching the video stream. When opening the file in DaVinci Resolve, there is two black frames in beginning.

    


    I used this ffmpeg command :

    


    ffmpeg -i file.mp4 -map_metadata 0 -c:v copy -c:a pcm_s16le file.mov


    


    For some reason this command changes timestamp info :

    


    file.mp4
---
"start_pts": 0,
"start_time": "0.000000",
"duration_ts": 519000,
"duration": "20.760000",
"bit_rate": "80688676",

file.mov
---
"start_pts": 2000,
"start_time": "0.080000",
"duration_ts": 517000,
"duration": "20.680000",
"bit_rate": "81000818",


    


    I also get this error when converting file :

    


    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x565392b65800] st: 0 edit list: 1 Missing key frame while searching for timestamp: 1000


    


    I found this bug report, but there didn't found any fixes to my problem.

    


    file.mp4 edit lists looks like this :

    


    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x561fc98ff800] track[0].edit_count = 1
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x561fc98ff800] Processing st: 0, edit list 0 - media time: 1000, duration: 519000

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x561fc98ff800] Processing st: 1, edit list 0 - media time: 0, duration: 996353


    


    AAC timecode and H265 has almost same duration withoat the media time: 1000 starting time :

    


    AAC timebase is 1/48000

    


    996353/48000 = 20.75735416666666666667


    


    H265 timebase is 1/25000

    


    519000/25000 = 20.76


    


  • convert using ffmpeg without exec

    26 avril 2017, par Ronan Dejhero

    I have Windows XP, Apache, PHP 5.3 and ffmpeg working fine. I need to convert flv to avi or vice versa without using the exec() command. Is this possible ?

    Thank you.

    edit :
    i hope someone could edit the ffmpeg source and implement an exec function into the php extension so we could just add the parameters to a function (ex $fmpeg->exec(’exec parameters here’) ; ) so the exec is executed directly from the extension ...

    and compile those file :p
