    Le thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.

  • How to use ffmpeg encode video in H.264 ?

    7 mai 2016, par seaguest

    I have installed ffmpeg 3.0 from https://github.com/FFmpeg/FFmpeg, I am trying to convert a video coded with mepeg4 part 2 to H264, but I got Unknown encoder 'libx264'
    error

    Here is my comannd : (I tried h264, x264, libx264, none of them worked)

    ffmpeg -i Fashion.divx -acodec aac -vcodec libx264  out.mp4

    I checked the list of supported codec

    Codecs:
    
 D..... = Decoding supported
    
 .E.... = Encoding supported
    
 ..V... = Video codec
    
 ..A... = Audio codec
    
 ..S... = Subtitle codec
    
 ...I.. = Intra frame-only codec
    
 ....L. = Lossy compression
    
 .....S = Lossless compression
    
 -------
    
 D.VI.. 012v                 Uncompressed 4:2:2 10-bit

    Here is h264 :

     D.V.LS h264                 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_vdpau)

    I am using ffmpeg 3.0, from that list, it seems that encoding with h264 is not supported, only decoding h264 is supported, right ?

    I tried to enable h.264 with this guide
    How to quickly compile FFmpeg with libx264 (x264, H.264)

    ./configure --enable-gpl --enable-libx264

    bu I get
    ./configure —enable-gpl —enable-libx264

    ERROR: libx264 not found
    

    
If you think configure made a mistake, make sure you are using the latest
    
version from Git.  If the latest version fails, report the problem to the
    
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    
Include the log file "config.log" produced by configure as this will help
    
solve the problem.

    what should I do to make encode video in h.264 work ?

  • How can we extract the RTP packet sequence number from AVPacket (ffmpeg)

    6 septembre 2019, par Nech

    We are trying to extract the "Sequence Number" from the RTP header of a packet.
    We use av_read_frame in order to read the packets into AVPacket structs.

    We tried using the AVPacket.data field, hoping it holds the original payload, but we didn’t manage to find the right location of the header. So we assume that the data field does not hold the full payload - please correct if we are wrong.

    Is there a way to find the RTP header information ?
