  • Error compiling libx264 : Undefined symbols for architecture x86_64

    11 juin 2015, par elu

    I have ffmpeg installed, and I am trying to compile libx264 but keep getting an error. Most of the results I've found from searching are about issues compiling ffmpeg or configuring it with libx264 but I can't seem to even get libx264 to compile.

    Here is the error:

  • x264enc plugin settings for VBV buffer

    11 juin 2015, par Dundar

    I am trying to implement VBV buffer in x264enc plugin in gstreamer. What I want to achieve is setting rc.i_vbv_max_bitrate to 10K and rc.i_vbv_buffer_size to 10K. However, what I see in the x264enc source code,

    encoder->x264param.rc.i_vbv_max_bitrate = encoder->bitrate;
encoder->x264param.rc.i_vbv_buffer_size
      = encoder->x264param.rc.i_vbv_max_bitrate
      * encoder->vbv_buf_capacity / 1000;

    Here is my settings:

     g_object_set(G_OBJECT(_videoEncoder),
                 "tune",             (guint)4,
                 "speed-preset",     (guint)1,
                 "byte-stream",      (gboolean)TRUE,
                 "bitrate",          (guint) 10000,
                 "vbv-buf-capacity", (guint) 1000,
                 "intra-refresh",    (gboolean)TRUE,
                 NULL);

    Do you see anything wrong in this? tune=4 means ultrafast, speed-preset=1 means zerolatency right?

    Thanks.

  • How to encode a series of .dpx files using X264

    4 juin 2015, par user3759710

    I am complete newbie to video encoding. I am trying to encode a series of .dpx files into one single encoded video O/P file in any of the following format. ( .mp4,.avi,.h264,.mkv etc)

    I have tried 2 different approaches. The first one works and the second one does not. I would like to know the difference between the two. Any help / input would be much appreciated.

    1) using FFMPEG along with x264 library and it works well. I am able to produce desired output

    ffmpeg -start_number 0 -i frame%4d.dpx -pix_fmt yuv420p -c:v libx264 -crf 28 
-profile:v baseline fromdpx.h264

    2) I first try to concatenate all the dpx files into a single file using concate protocol in ffmpeg and then use x264 to encode the concatenated file. Here I see that the size of the concatenated file is the sum of all the files concatenated. But when I use x264 command to encode the concatenated file, I get a green screen (basically not the desired output) . 

    ffmpeg -i "concat:frame0.dpx|frame01.dpx|frame2.dpx etc" -c copy output.dpx

    then 

    x264 --crf 28 --profile baseline -o encoded.mp4 --input-res 1920x1080 --demuxer raw 
output.dpx

    I also tried to encoded the concatenated file using ffmpeg as follows

    ffmpeg -i output.dpx -pix_fmt yuv420p -c:v libx264 -crf 28 -profile:v baseline fromdpx.h264

    This also gives me a blank video.

    Could someone please point out to me what is going on here? Why does the first method work and the second does not?

    Thank you.

  • Build FFMPEG with libx264 Android

    4 juin 2015, par Biraj Zalavadia

    I was able to Build FFMPEG with libx264 Android successfully and was working well before 2 months.

    I uses halfninja for building.

    Today I take latest source of ffmpeg and libX264 from here.

    git clone git://git.videolan.org/x264.git

git clone git://git.videolan.org/ffmpeg.git

    And try to rebuild whole project. But now it throws following errors.

  • -fps filter not in avconv ?

    22 avril 2015, par user2392940

    Used a older version of ffmpeg on a project and now im planning on switching over to avconv and was wondering if the -fps filter has been changed or depreciated? If it has been changed what is the current substitute for the -fps filter in avconv? Much Thanks
