    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.

  • How to keep highest value of ffmpeg crop detect

    13 décembre 2020, par Vincent Duprez

    Case :

    



    I'm converting an old archive of 18000 commercials 
I'd like to automate this reconversion from DV to some lighter and uptodate h264 mp4

    



    The whole process is ready but I'm stuck at the first part : cropping the black bars...

    



    Tools used :

    



    The thing is : all videos are different, I cannot use one static value, thus I use the wonderful cropdetect tool by ffmpeg which outputs me this kind of lines in the cli :

    



    [Parsed_cropdetect_0 @ 0xbe5e960] x1:22 x2:697 y1:93 y2:483 w:672 h:384 x:24 y:98 pts:63 t:2.520000 crop=672:384:24:98
[Parsed_cropdetect_0 @ 0xbe5e960] x1:22 x2:697 y1:93 y2:483 w:672 h:384 x:24 y:98 pts:64 t:2.560000 crop=672:384:24:98
[Parsed_cropdetect_0 @ 0xbe5e960] x1:22 x2:697 y1:93 y2:484 w:672 h:384 x:24 y:98 pts:65 t:2.600000 crop=672:384:24:98
[Parsed_cropdetect_0 @ 0xbe5e960] x1:22 x2:697 y1:93 y2:496 w:672 h:400 x:24 y:96 pts:66 t:2.640000 crop=672:400:24:96
[Parsed_cropdetect_0 @ 0xbe5e960] x1:2 x2:717 y1:80 y2:496 w:704 h:416 x:8 y:80 pts:67 t:2.680000 crop=704:416:8:80
[Parsed_cropdetect_0 @ 0xbe5e960] x1:1 x2:718 y1:80 y2:496 w:704 h:416 x:8 y:80 pts:68 t:2.720000 crop=704:416:8:80
[Parsed_cropdetect_0 @ 0xbe5e960] x1:1 x2:718 y1:80 y2:496 w:704 h:416 x:8 y:80 pts:69 t:2.760000 crop=704:416:8:80
[Parsed_cropdetect_0 @ 0xbe5e960] x1:1 x2:718 y1:80 y2:496 w:704 h:416 x:8 y:80 pts:70 t:2.800000 crop=704:416:8:80
[Parsed_cropdetect_0 @ 0xbe5e960] x1:1 x2:718 y1:80 y2:496 w:704 h:416 x:8 y:80 pts:71 t:2.840000 crop=704:416:8:80


    



    So the last part : crop= gives the result of the remaining frame (width, hight, starting x point starting y point. to crop the video..

    



    But these values are not always the same inside one video how can I extract 'the biggest values' out of these hundreds of lines ?

    



    In this case, just keep crop=704:416:8:80

    



    Edit

    



    Actually, the result should take in account the lowest x1, highest x2, lowest y1 and highest y2, then create a rectangle multiple of 16 inside it...

    


  • iOs : Low frame per second(fps) for VGA resolution

    26 juillet 2014, par Bhuvan Balasubramanian

    I’m facing an issue in broadcasting video from one iPhone to another iPhone.

    The issue is when I view the friend’s live video in my iPhone, the frame per second(fps) is very low(it is 12fps). Video quality and audio is looking fine but the only problem is fps.

    I don’t know where I need to config/change the code to convert from variable fps to constant fps. Also to increase the fps as **24/30**.

    The resolution I used for broadcasting

    RESOLUTION_VGA,     // 480x640px (landscape) & 640x480px (portrait)

    I’m using following libraries for streaming

    1. MediaLibiOS - link
    2. Ffmpeg-2.2.1
    3. CommLibiOS
    4. libx264-r2409

    Wowza is a Media Server and iOS target version is 7.0

    Please help !

    Thanks in advance.

  • How to create a video thumbnail without ffmpeg or HTML5 video canvas ? [duplicate]

    14 mai 2014, par user3631926

    This question already has an answer here :

    I need to create a thumbnail from a video, I have tried the below options but they didn’t work for my case. I am using S3 and CloudFront.

    1. ffmpeg is not supported via my hosting because I am using a shared hosting and I need to upgrade to VPS or dedicated server if I want to use ffmpeg.

    2. I tried taking a screenshot from the video using HTML5 drawImage and toDataURL functions, but it is throwing SecurityError because my video file is located on Amazon CloudFront and my code is hosted somewhere else.

    Is there any other option or a workaround to the second option ? I don’t want to upgrade my server for just the thumbnail issue.
