Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

MediaSPIP Player : problèmes potentiels
22 février 2011, parLe lecteur ne fonctionne pas sur Internet Explorer
Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)

MediaCodec hardware decoder much slower with different server configuration ?
19 octobre 2013, par mathieujofisI've been using the Android
MediaCodec
in order to (hardware) decodeH.264
frames on myGalaxy S4
coming from a Live 555RTSP
live (real-time) stream. After changing my Live 555 server configuration from usingffmpeg
(withx264
) to encode frames, to using strictlyx264
to encode frames, the time to decode frames withMediaCodec
takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back toffmpeg
isn't a solution for me, because I need the ability to encode into discreteNAL
units, rather than a whole frame likeffmpeg
does.I was wondering if this was either : A) An issue with the way my server is encoding
NAL
units, or B) An issue with my Android client, specifically the way it is receiving and decodingNAL
units.My encoding configuration with x264 is :
x264_param_default_preset(&param,"ultrafast", "zerolatency:fastdecode");
param.i_threads = 1;
param.i_bframe = 1;
param.i_width = image_width;
param.i_height = image_height;
param.i_fps_num = 60;
param.i_fps_den = 1;
param.i_keyint_max = 10;
param.rc.i_rc_method = X264_RC_ABR;
param.rc.i.bitrate = 6000;
param.i_sps_id = 7;
param.b_repeat_headers = 1;
param.b_annexb = 0;My Android MediaCodec client is set up as follows :
I receive each individual
NAL
unit on a separate Live 555RTSP
client thread. EachNAL
is put into a queue along with its size and presentation time. A separate decoder thread grabsNALs
from this queue, and if there are none available, waits until there are.Some notes :
What I generally see happen is the queue starts filling up with
NALs
, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates— also again, it DID work when I was usingffmpeg
to encode. If I omit certainNAL
units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.Edit :
Here is a log of the Android client, as well as a log highlighting the garbage collector specifically—

Conversion for WebM file format using FFMPEG
23 mars 2012, par user974435I am using followng command to convert video to webm format
ffmpeg -i video/ds2.mp4 -acodec libvorbis -ac 2 -ab 96k -ar 44100 -b:a 345k -s 640x360 video/ds2.webm
I am receiving following errors :
1) incompatible sample format 's16' for codec 'libvorbis'
2) strptime() unavailable on this system, cannot convert the data string
Do you any idea why I cannot convert, tested conversion to FLV and it's working very well
Console output

Has anyone gotten a windows build of FFMPEG to publish to Akamai's CDN via RTMP ?
3 décembre 2013, par Ken ConnerI am trying to live stream a file to Akamai's servers via RTMP from flash and I cannot get past the authentication step even though I know I am using the right username and password (the credentials work in FMLE). I Have found some posts online but they are older and its difficult because no one ever reports what build of FFMPEG they are using.
Has anyone gotten this to work with Windows binaries ?
