  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • ffmpeg error : Too large number of skipped frames xxxxx > 60000

    16 septembre 2019, par Fulkron

    I try to record on RasperryPI from usb Cam (/dev/video0) using segments to obtain sliced video.
    The command I’m using is :

    ffmpeg -input_format mjpeg -video_size 640x480 -i /dev/video0 -y -y -f v4l2 -an -pix_fmt yuv420p -codec copy -f segment -segment_time 60 -segment_wrap 10 -t 180 stream/looper%02d.avi

    I got an error after 2 minutes about skipped frames (see later for detail).
    Is I run the same command without segmentation is working.

    I tested on different HW, with different segment parameters, with different usb cam but the situation still the same.

    Here there is the output :

10_____________AO905326704670____10_________.apc: Invalid data found when processing input

  • Invalid data found when processing file with ffmpeg API

    18 septembre 2019, par Timmy K

    I have an m4a file containing two AAC-encoded audio streams. I want to decode it on Android with the ffmpeg library. However, avformat_open_input() fails with "Invalid data found when processing input".

    This file was created (i.e. the audio data encoded) with the same library.

    I’ve double-checked the accuracy of the file path I provide to the call.

    The file doesn’t appear to be corrupt. It plays with QuickTime player, and ffprobe reports the output below.

    I’ve looked at the source in ffmpeg’s utils.c but it’s not clear at which of several points (including nested calls) this invalidity of the data in the file is being decided.

    The call that fails with "invalid data found" is :

     if ( (ret = avformat_open_input( &inputFormatContext, filePath, 0, 0)) < 0 )
    
  {
    
    __android_log_print(ANDROID_LOG_DEBUG, "MyTag", "Could not open input file '%s' error %s ", filePath, av_err2str(ret) );
    
      return false;
    
  }

    I would expect this to "just work" since I encoded and muxed the two audio tracks with the same build of the ffmpeg libraries.

    When I built the libraries, I configured the build with :

    —enable-decoder=aac,pcm_s16le —enable-encoder=aac,pcm_s16le —enable-demuxer=mp4,wav —enable-muxer=mp4,wav —enable-protocol=file,http

    When I iterate through the codecs using av_codec_iterate() and look for supported sample rates I see :

    Found codec aac
    
supported sample rate 96000
    
supported sample rate 88200
    
supported sample rate 64000
    
supported sample rate 48000
    
supported sample rate 44100
    
supported sample rate 32000
    
supported sample rate 24000
    
supported sample rate 22050
    
supported sample rate 16000
    
supported sample rate 12000
    
supported sample rate 11025
    
supported sample rate 8000
    
supported sample rate 7350
    
Found codec pcm_s16le
    
Found codec aac
    
Found codec pcm_s16le

    Each codec appears twice, which I thought was maybe the encoder and decoder. But I note that only one has any supported sample rates. My test files’ sample rate is 44100.

    Any thoughts on what other things I can check for ? I wondered whether I should create and pass an AVInputFormat object explicitly to the call, based upon what I know about the contents of the file. But I don’t know how to construct one.
