  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Not able to change H264 profile to High from Main using FFMPEG API

    7 juin 2015, par AsG

    I am using QtFFMPEG wrapper(https://code.google.com/p/qtffmpegwrapper/) with Qt 5.4 and MSCV 2012. I want to encode a mp4 video from image files at 25 fps and high profile.
    I used the createFile() and encodeImage() functions from here

    I am using the below parameters :

    pCodecCtx=pVideoStream->codec;
    
pCodecCtx->codec_id = pOutputFormat->video_codec;
    
pCodecCtx->codec_type = ffmpeg::AVMEDIA_TYPE_VIDEO;
    
pCodecCtx->profile=FF_PROFILE_H264_HIGH;
    
pCodecCtx->bit_rate = Bitrate;
    
pCodecCtx->width = getWidth();
    
pCodecCtx->height = getHeight();
    
pCodecCtx->time_base.den = fps;
    
pCodecCtx->time_base.num = 1;
    
pCodecCtx->gop_size = 10;
    
pCodecCtx->pix_fmt = ffmpeg::PIX_FMT_YUV420P;
    
pCodecCtx->qmin = 10;
    
pCodecCtx->qmax = 51;

    The FFMPEG variables are :

    License: %s

AVCodec version %d

    Now I currently get a video with below properties :

    ID                             : 1
    
Format                         : AVC
    
Format/Info                    : Advanced Video Codec
    
Format profile                 : Main@L3.2
    
Format settings, CABAC         : No
    
Format settings, ReFrames      : 1 frame
    
Format settings, GOP           : M=1, N=10
    
Codec ID                       : avc1
    
Codec ID/Info                  : Advanced Video Coding
    
Duration                       : 4s 320ms

    I want the profile to be "High" and the CABAC to be yes with 3 ReFrames. How do I achieve that ? I tried setting the profile, coder_type and max_b_frames but did not help. At times the generated file did not even play. Can anyone help please. Thanks.

    I also tried using the av_opt_set() way but could not find that function. Only function I have is av_opt_set_dict(), am I missing something - outdated FFMPEG or missing #include.

    Tried this too, didnt help-

       ffmpeg::AVDictionary *opt = NULL;
    
   int iRes = av_dict_set(&opt, "profile", "high", 0);
    
   av_opt_set_dict(pFormatCtx->priv_data, &opt);
    
   av_opt_set_dict(pFormatCtx, &opt);

    Please help.

    EDIT :
    I got a high quality mp4 by changing the qmin and qmax values and then reencoding the big sized output via command line. I will try to upgrade the FFMPEG as suggested by Ronald below. Please consider the question closed for now.

  • ffprobe or avprobe returning plain text errors in JSON output

    6 mai 2015, par Justin Jenkins

    I’m running avprobe to get stream infomation about a video in JSON ...

    avprobe -loglevel quiet -show_format -show_streams file.m4v -of json

    This is basically the exact same thing as ffprobe or ffmpeg -i (and I get the same error.)

    ffprobe -loglevel quiet -show_format -show_streams file.m4v -print_format json

    The command works most of the time ... however, on occation I’ll have a video that has an odd stream in it that is "unsupported" and I’ll get back something like this (abbreviated.)

    Unsupported codec with id 94213 for input stream 2
    
{  "format" : {
    
    "filename" : "file.m4v",
    
    "nb_streams" : 3,
    
    "format_name" : "mov,mp4,m4a,3gp,3g2,mj2" ...

    When I run the command I get back JSON + an error in plain text, which makes the result invalid JSON and I have to "clean it up" later.

    I’m suppressing errors from the output -loglevel quiet but the error still show up.

    How can I tell avprobe/ffprobe to not show this error and hence get back a proper JSON object ?

  • How do you compile Winff ?

    3 mai 2015, par Richard

    I downloaded the WinFF source code in the hopes the new version would solve a segfault.

    It’s sitting, extracted, in its folder. But I see no ./configure, nothing make would know what to do with, no binaries, and no compilation instructions :

    $ ls
    
AUTHORS        COPYING           README-Presets.txt  unit2.lfm  unit4.pas  winff.1      winff.rc
    
changelog.txt  docs              README.txt          unit2.pas  unit5.lfm  winff.ico
    
clean.bat      languages         RESOURCES.RC        unit3.lfm  unit5.pas  winff-icons
    
clean.sh       potranslator.pas  unit1.lfm           unit3.pas  unit6.lfm  winff.lpi
    
COMPILE.TXT    presets.xml       unit1.pas           unit4.lfm  unit6.pas  winff.lpr

    Does anyone know how I can try to actually compile the code ?

    All we get is a README.txt :
