  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Android FFmpeg sometimes works and sometimes crashes

    20 novembre 2013, par Pawel Cala

    I compiled FFmpeg for Android ( https://gitorious.org/android-ffmpeg ) but when I'm trying to do some operations ( f.e filters cropping, transpose, trim etc ) it crashes in 5 on 10 cases.
    Error logs are not the same so I assume that it might be caused by memory issues.
    I'm using OSX, NDK android-ndk-r9b : darwing x86_64.
    Native ffmpeg method is passing args to ffmpeg.c main method. It's executed in AsyncTask in Activity.
    Thanks in advance

    EDIT :
    I forgot to mention that programs algorithm runs like that :
    Press Button - > Open Camera Intent - > Start recording - > After recording copy file to project folder ( on SD card ) - > Open edit activity + Start asynctask

    EDIT2 :
    Tested on HTC ONE with different video resolutions

  • Retrieving RTP time from an IP camera programatically using FFMPEG

    22 novembre 2013, par Dídac Pérez

    I am using the ffmpeg C/C++ library to get the video stream from an IP camera using methods such as avformat_open_input(), av_read_frame(), etc... I would like to get the RTP time from the camera. pts and dts values give me the relative timestamp to the first frame, but I need the absolute date (i.e. 2013/11/22 12:40:30.123) and time since as I read, at the RTP layer the time is sent by the camera, and I have also configured the camera to use the dime from an NTP server.

    Please, I am really confused and I have tried everything without success, I am not able to find this date and time. Any help will be really appreciated, thank you so much.

  • ffmpeg m3u8 segment file and relative path for file names

    15 mars 2013, par Luuk D. Jansen

    This must be a simple issue, but I have a difficulty with the M3U8 file created by FFMPEG as it contains the absolute path to the files, and not just the file names which I need. I am trying to be able to view the stream while it is encoded, and this seems the last hurdle.

    My FFMPEG command is (ignore the comma's) :

    ffmpeg, -i, /Users/User/Documents/Java/server/data/media/1/1/Promo-2013.mov, -dn, -y, -f, mpegts, -c:a, libfdk_aac, -strict, -2, -ar, 48000, -b:a, 128000, -s, 640x360, -c:v, libx264, -b:v, 700000, -aspect, 640:360, -r, 25, -level, 3.0, -vprofile, baseline, -flags, +loop, -cmp, chroma, -coder, 0, -me_range, 16, -keyint_min, 25, -sc_threshold, 40, -i_qfactor, 0.71, -bt, 200k, -maxrate, 700000, -bufsize, 700000, -rc_eq, 'blurCplx^(1-qComp)', -qcomp, 0.6, -qmin, 10, -qmax, 51, -qdiff, 4, -level, 30, -g, 30, -async, 2, -partitions, +parti4x4+partp8x8+partb8x8, -subq, 5, -trellis, 1, -refs, 1, -vbsf, h264_mp4toannexb, -flags, -global_header, -map, 0, -f, segment, -segment_time, 10, -segment_list, /Users/User/Documents/Java/server/data/media/1/3/prog_index.m3u8, -segment_list_flags, +live, -segment_format, mpegts, /Users/User/Documents/Java/server/data/media/1/3/segment_%05d.ts

    The resulting file is :

    #EXTM3U
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-ALLOW-CACHE:YES
    
#EXT-X-TARGETDURATION:12
    
#EXTINF:10.005333,
    
/Users/User/Documents/Java/server/data/media/1/10/segment_00000.ts
    
#EXTINF:11.952000,
    
/Users/User/Documents/Java/server/data/media/1/10/segment_00001.ts
    
#EXTINF:10.002667,

#EXTINF:0.266667,
    
/Users/User/Documents/Java/server/data/media/1/10/segment_00004.ts
    
#EXT-X-ENDLIST

    It all works perfect, but I only want e.g. 'segment_00000.ts, and not the complete absolute path, as that is of no use for live streaming. As this is a very ordinary application, I must do something wrong.
