  • Gstreamer AAC encoding no more supported ?

    22 juillet 2016, par Gianks

    i’d like to include AAC as one of the compatible formats in my app but i’m having troubles with its encoding.
    FAAC seems to be missing in GStreamer-1.0 Debian-derived packages (see Ubuntu) and the main reason for that (if i got it correctly) is the presence of avenc_aac (Lunchpad bugreport) as a replacement.

    I’ve tried the following :

    gst-launch-1.0 filesrc location="src.avi" ! tee name=t  t.! queue ! decodebin ! progressreport ! x264enc ! mux. t.! queue ! decodebin ! audioconvert ! audioresample ! avenc_aac compliance=-2 ! mux. avmux_mpegts name=mux ! filesink location=/tmp/test.avi

    It hangs prerolling with :

    ERROR libav :0:: AAC bitstream not in ADTS format and extradata missing

    Using mpegtsmux instead of avmux_mpegts seems to work since the file is created but it results with no working audio (with some players it’s completely unplayable).

    This is the trace of mplayer :

    Using the error of the hanging pipeline I’ve finally discovered that avenc_aac should be told in such way to output the data NOT in RAW AAC but in ADTS AAC, the point is that i’ve no idea how to do that with Gstreamer. See here, bottom of the page : FFMPEG Ticket

    At this point since i’ve found no documentation seems right to say we have no support for AAC encoding in GStreamer... which isn’t true, i guess ! (IMHO anyway seems strange the missing of FAAC if AVENC_AAC requires all the time to be set in experimental mode)

    Can someone propose a working pipeline for this ?

    UPDATE

    After some more research i’ve found (via gst-inspect on avenc_aac) what i’m probably looking for but i don’t know how to setup it as needed.
    Have a look at stream-format :

  • How do I get videos to upload using carrierwave-video ?

    10 juillet 2016, par Eric

    I tried to follow the instructions on github to upload using carrierwave-video, but get an error that says the file or directory mmpeg -i doesn’t exist.

    The upload path for images is correct, just not the video one.

    I added all of the following code necessary to help solve the error and minified as much as I possibly could.

    This is the video uploader code using carrierwave :

    class VideoUploader < CarrierWave::Uploader::Base
    

    
  include CarrierWave::Video
    
  storage :file
    

    
  version :mp4 do
    
    process :encode_video => [:mp4, resolution: "100x100"]
    
  end
    

    
  def store_dir
    
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    
  end
    
end

    This is the movie controller code that handles uploading of videos :

    class MoviesController < ApplicationController
    
   include MoviesHelper
    

    
   def index
    
      mode "index"
    
   end
    

    
   def show
    
      mode "show"
    
   end
    

    
   def new
    
      mode "new"
    
   end
    

    
   def edit
    
      mode "edit"
    
   end
    

    
   def create
    
      mode "create"
    
   end
    

    
   def update
    
      mode "update"
    
   end
    

    
   def destroy
    
      mode "destroy"
    
   end
    

    
   def review
    
      mode "review"
    
   end
    

    
   def approve
    
      mode "approve"
    
   end
    

    
   def deny
    
      mode "deny"
    
   end
    
end

    This is the model data for the movie that goes with it :

    class Movie < ActiveRecord::Base
    
  attr_accessible :created_on, :description, :maintenance, :reviewed, :subplaylist_id, :title, :user_id, :video, :remote_video_url
    
  belongs_to :user
    
  belongs_to :subplaylist
    
  mount_uploader :video, VideoUploader
    
end

    This is where the movie is supposed to be displayed but it is not working :

    <% provide(:title, "Movie: Where movies are made!") %>
    
<% provide(:keywords, "movies, video") %>
    
<% provide(:description, "This is the place where users showcase their wonderful video talent.") %>
    
<p>&lt;%= notice %></p>
    
<h1 class="pageheader">&lt;%= @movie.title %></h1>
    
<br />
    
<p class="pagetext">&lt;%= video_tag(@movie.video_url.to_s, controls: true, class: "imagebox") %></p>
    
<p class="pagetext">&lt;%= @movie.description %></p>
    
<p class="pagetext">Created on: &lt;%= @movie.created_on.strftime("%B-%d-%Y") %></p>
    
<p class="pagetext">Owner: &lt;%= getType(@movie.user) %>&lt;%= link_to @movie.user.vname, user_path(@movie.user) %></p>
    
<br />
    
<p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @movie.subplaylist) %></p>

    This is where the movie new action is :

    &lt;% provide(:title, "Movie: Create new movies here!") %>
    
&lt;% provide(:description, "New movies are uploaded only to the site when the movie gets approved.") %>
    
<h1 class="pagetextheader">New movie</h1>
    
&lt;%= render 'form' %>
    
<p class="pagetext">&lt;%= link_to 'Back', mainplaylist_subplaylist_path(@subplaylist.mainplaylist, @subplaylist) %></p>

    This is where the movies forum parameters are :

    &lt;%= form_for([@subplaylist, @movie], :html=>{:multipart => true}) do |f| %>
    
  &lt;% if @movie.errors.any? %>
    
    <div>
    
      <h2>&lt;%= pluralize(@movie.errors.count, "error") %> prohibited this movie from being saved:</h2>
    

    
      <ul>
    
      &lt;% @movie.errors.full_messages.each do |msg| %>
    
        <li>&lt;%= msg %></li>
    
      &lt;% end %>
    
      </ul>
    
    </div>
    
  &lt;% end %>
    
  <br />
    
  <div class="pagetext">
    
    &lt;%= f.label :title %><br />
    
    &lt;%= f.text_field :title %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.file_field :video %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.label :remote_video_url, "or video URL" %><br />
    
    &lt;%= f.text_field :remote_video_url %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.label :description %><br />
    
    &lt;%= f.text_area :description %>
    
  </div>
    
  <div class="pagetext">
    
    &lt;%= f.submit %>
    
  </div>
    
  <br />
    
&lt;% end %>

  • Undefined references while using ffmpeg 2.1.1 for Android

    2 décembre 2013, par Kernald

    I'm building ffmpeg following the same pattern as halfninja's build : make the ffmpeg's main available from Java through JNI. I built ffmpeg with the following options :

    ./configure \
    
    --prefix=$PREFIX \
    
    --disable-shared \
    
    --enable-static \
    
    --disable-doc \
    
    --disable-ffmpeg \
    
    --disable-ffplay \
    
    --disable-ffprobe \
    
    --disable-ffserver \
    
    --disable-doc \
    
    --disable-symver \
    
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    
    --target-os=linux \
    
    --arch=arm \
    
    --enable-cross-compile \
    
    --sysroot=$SYSROOT \
    
    --extra-cflags="-Os -fpic $ADDI_CFLAGS" \
    
    --extra-ldflags="$ADDI_LDFLAGS"

    $PREFIX, TOOLCHAIN, … being set to corresponding folders from my NDK. $ADDI_CFLAGS is set to -marm and $ADDI_LDFLAGS and $ADDITIONAL_CONFIGURE_FLAGS are both unset. The resulting static libraries are created :

    $ ls -1 android/arm/lib/
libavcodec.a
libavdevice.a
libavfilter.a
libavformat.a
libavutil.a
libswresample.a
libswscale.a
pkgconfig

    I expose them with an Android.mk file, ffmpeg being built in $NDK/sources/ffmpeg-2.1.1 :

    LOCAL_PATH:= $(call my-dir)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libavdevice
    
LOCAL_SRC_FILES:= lib/libavdevice.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libavcodec
    
LOCAL_SRC_FILES:= lib/libavcodec.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libavformat
    
LOCAL_SRC_FILES:= lib/libavformat.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libswscale
    
LOCAL_SRC_FILES:= lib/libswscale.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libavutil
    
LOCAL_SRC_FILES:= lib/libavutil.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libavfilter
    
LOCAL_SRC_FILES:= lib/libavfilter.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE:= libwsresample
    
LOCAL_SRC_FILES:= lib/libswresample.a
    
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
    
include $(PREBUILT_STATIC_LIBRARY)

    So, up to there, everything looks good. Now, I try to build the ffmpeg binary equivalent as a static library. I copied (and didn't change a single character for now) ffmpeg.c, ffmpeg.h, cmdutils.c, cmdutils.h, ffmpeg_opt.cand ffmpeg_filter.c in my jni folder. I also have two directly JNI-related files in this folder (copied from halfninja's build, I just changed the package name). Here's the relevant Android.mk :

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)
    
LOCAL_C_INCLUDES := /Applications/android-ndk-r9b/sources/ffmpeg-2.1.1
    
LOCAL_CFLAGS := -Wdeprecated-declarations
    
LOCAL_MODULE := videokit
    
ANDROID_LIB := -landroid
    
LOCAL_LDLIBS += -llog -ljnigraphics -lz 
    
LOCAL_SRC_FILES := videokit/com_rfc_video_ffmpeg_Videokit.c videokit/ffmpeg.c videokit/cmdutils.c videokit/ffmpeg_opt.c videokit/ffmpeg_filter.c
    
LOCAL_SHARED_LIBRARIES := libavdevice libavformat libavfilter libavcodec libwscale libavutil libswresample libswscale libpostproc
    
include $(BUILD_SHARED_LIBRARY)
    
$(call import-module,ffmpeg-2.1.1/android/arm)

    Everything compiles fine, but doesn't link. Here are the first errors :

    What I don't understand is that these functions are defined and available in libswresample.a, which I'm linking to :

    arm-linux-androideabi-nm /Applications/android-ndk-r9b/sources/ffmpeg-2.1.1/android/arm/lib/libswresample.a  | grep -i -e swr_get_class -e swresample_version
000001d4 T swr_get_class
00000178 T swresample_version

    What am I doing wrong ? Is there another, maybe simpler way to expose ffmpeg as a static library available via JNI ? (I don't use halfninja's because I need at least ffmpeg 1.1, while his is in 0.9).
