  • 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 (...)

  • Checking processor capabilities in android

    29 avril 2014, par StackOverflowed

    I’m using FFMPEG in an app, and I’m using the following configuration :

    --extra-cflags=' -march=armv7-a -mfloat-abi=softfp -mfpu=neon'

    I’m targeting 4.0+ so I believe armv7-a should be supported by most non Intel devices, and I’m sure the neon extension is supported in most devices as well, but I’m not sure how I can find that out for all 2000+ devices.

    Is there a way to check in Android the processor type and extensions and/or in the Google Play Store to limit the apk to devices with certain processors ?

  • ffmpeg HLS creation and segmentation results in "cannot decode" on iPad

    5 mai 2014, par jt_dylan

    I have the following code that plays on Mac Safari :

        
    
       
    
       
    
       
    

    
    <video controls="controls" width="480" height="270">
    
    
    
    <source src="http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/  hls/MVI_5927.m3u8">
    
    </source></video>

    The url can be cut/pasted into the browser and works also but neither this code nor the url works in Windows Safari or iPad. Specifically on iPad I receive a cannot decode error. On Mac I have Quicktime installed so I tried that on Windows with no luck. The link that can be play on Mac is below.

    http://d1ckv7o9k6o3x9.cloudfront.net/d54cfa01-eff2-4e86-946e-dc8b2ee4a7e8/media/hls/MVI_5927.m3u8

    Browser Versions of software :
    Mac Safari : Version 7.0.3 (9537.75.14) (works)
    Windows Safari : Version 5.1.7 (7534.7.2) (doesn’t work - blank screen)
    iPad Safari : ios Version 7.1.1 (doesn’t work - cannot decode)

    Here is how I’m creating my mp4 (lgpl)
    I’m creating an mp4 with this command :
    ffmpeg -i input.mov c:v mpeg4 q:v 1 test.mp4

    I’m creating the hls using ffmpeg lpgl with this command :

    ffmpegcmd -re -y -i test.mp4 -map 0 -f segment -segment_list test.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test%05d.ts 2>&amp;1

    Now this works in Mac Safari with Quicktime installed but results in "cannot decode" if I try the url from ipad Safari.

    I then tried with libx264 to create the mp4 as h.264 with aac and then copy to mpeg2 container as follows :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4
    
ffmpeg -i test.slower.mp4 -vcodec copy -f mpegts -bsf h264_mp4toannexb test.slower.ts
    
ffmpeg -re -y -i test.slower.ts -map 0 -f segment -segment_list test.slower.m3u8 -segment_list_flags +live -segment_time 1 -segment_list_type m3u8 test.slower.%05d.ts

    This still produces the same results. Any idea what is wrong here ?

    Any help is much appreciated.

    Regards,
    jt_dylan

    Output from libx264 commands below :

    ffmpeg -i test.mov  -c:v libx264 -c:a libfdk_aac -preset slower -b:a 240k test.slower.mp4

  • Correct command to transmit audio to ip camera using ffmpeg ?

    4 novembre 2016, par the_naive

    So I found some hints in this discussion on the correct command to transmit audio to Axis IP camera through using ffmpeg in windows, but still I have not managed to successfully transmit audio to the camera.

    The command I’m using is the following :

    ffmpeg -v debug -y -re -f dshow -i "audio=Microphone (2- High Definition Audio Device)" -c:a pcm_mulaw -ac 1 -ar 16000 -b:a 128k -f flv http://oper
    
ator:operator@10.10.210.2/axis-cgi/audio/transmit.cgi -multiple_requests 1 -reconnect_at_eof 1 -reconnect_streamed 1 -content_type "audio/basic" -report

    The ouput I get following this command is the following :
