  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Mobile Camera live audio/video streaming and encoding

    7 juin 2015, par Strikecounter2

    I know this question has been asked a couple of times, but I still haven’t found the right answer for my question.

    I would like to code an app that is able to live-stream audio and video while the content is being recorded and then uploaded to a server. I’d prefer to have my own back-end using Parse, because I want a high scalability. I know that the video has to be encoded to a h.264 codec and the audio to an AAC codec, but I don’t know how to achieve this. I have heard of the FFmpeg framework, but I am not sure if I would violate their license if I distribute my app or even sell it to somebody else.
    I would then like to receive the stream from the server to open it on the iPhone/android phone.

    They key requirements would be :

    • Low Latency
    • About 24 fps
    • Audio/Video in sync
    • No buffering while watching

    I would like to use Swift as a programming language, but if there is no way to use a swift-wrapper for any frameworks I would focus on Objective-C too.

    I am willing to learn everything that is needed, but I don’t know where to start.

  • gstreamer android error : engine.GetInterface(IODeviceCapabilities) failed(0x0000000c)

    19 juin 2015, par omerjerk

    I’m trying to stream mpegts file on an Android device. This is the file.

    I’ve setup everything as done in the tutorial 5 of gstreamer android.
    But I’m getting the following error -

    This is my Android.mk file :

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)
    

    
LOCAL_MODULE    := chestream
    
LOCAL_SRC_FILES := main.c
    
LOCAL_SHARED_LIBRARIES := gstreamer_android
    
LOCAL_LDLIBS := -llog -landroid
    
include $(BUILD_SHARED_LIBRARY)
    

    
ifndef GSTREAMER_SDK_ROOT
    
ifndef GSTREAMER_SDK_ROOT_ANDROID
    
$(error GSTREAMER_SDK_ROOT_ANDROID is not defined!)
    
endif
    
GSTREAMER_SDK_ROOT        := $(GSTREAMER_SDK_ROOT_ANDROID)
    
endif
    
GSTREAMER_NDK_BUILD_PATH  := $(GSTREAMER_SDK_ROOT)/share/gst-android/ndk-build/
    
include $(GSTREAMER_NDK_BUILD_PATH)/plugins.mk
    
GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS)\
    
mpeg2dec mpegdemux2 mpegtsdemux mpegtsmux ffmpeg
    
GSTREAMER_EXTRA_DEPS      := gstreamer-interfaces-0.10 gstreamer-video-0.10
    
include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer.mk

    The error is probably that gstreamer is not able to decode AAC file.
    Any help would be appreciated.

  • ffmpeg - Audio not playing on iOS with transcoded video

    23 juin 2015, par Dev

    I am using Laravel 4.2.

    I am working on a project that provides video services. To transcode video (to play on all devices) I’ve used git-hub package php ffmpeg.

    By transcoding video, I found it is NOT working with iPhone 5s. I searched for solution and found some changes in parameters passed to the library.

    Finally, I come up with the command below that the library uses to transcode the video.

    ffmpeg -y -i video.mp4 -async 1 -metadata:s:v:0 start_time=0 -s 560x320 
    
    -vcodec libx264 -strict experimental -pix_fmt yuv420p -profile:v baseline 
    
    -acodec aac -profile:a aac_low -b:v 466k -refs 6 -coder 1 -sc_threshold 40 
    
    -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 
    
    -trellis 1 -b:a 256k -ac 2 transcode_video.mp4

    The video is playing well but the audio is NOT working on iOS. Hence the video is playing without audio. I am using HTML 5 player to play the video and auto play option is off.

    Any suggestions ?
