  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec 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 to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg 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 decoding NAL 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 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs 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 using ffmpeg to encode. If I omit certain NAL 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—

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec 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 to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg 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 decoding NAL 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 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs 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 using ffmpeg to encode. If I omit certain NAL 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—

    At this step I have two problems :
    first is a warning during execution
    deprecated pixel format used, make sure you did set range correctly
    The second is the video do not work correctly in VLC (video is "black") but it work in wmp...

    Then I add an empty audio track :

    ffmpeg -threads 8 -f lavfi -i aevalsrc=0 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary_WithtoutAudio1.mp4" -vcodec copy -b:v 1500k -acodec aac -map 1:0 -map 0:0 -shortest -strict experimental -y "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4"

    After that I concat this video to others using complex filter .
    When I concat my videos I have this message :

    [output stream 0:1 @ 0451d3a0] 100 buffers queued in output stream 0:1, something may be wrong.

    And when i Watch the result my video freeze after the image insertion for a approximatly a seconde .
    perhaps it is not related
    I don't know ...

    Here my concat command and execution log

    D:\test>ffmpeg.exe -threads 8 -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary0.mp4" -i "D:\Records\2013-10-11_115453\PublishingDirectory\Temporary1.mp4" -i "D:\Records\2013-10-11_115
