  • FFMPEG creating MP4 video out of JPGs, but playback is instant

    19 décembre 2014, par lostPixels

    I have a NodeJS server that's taking JPG sequences and turning them into MP4's with libx264. For two of my three videos, everything is fine.

    However on one of my videos, the playback shoots from the beginning to the end in an instant. It's like the FPS is uncapped. The other odd thing about this is that the JPG files didn't seem to have a content-length header when I downloaded them. I'm not sure if that's related or not.

  • ffmpeg conversion x264 [error] : malloc of size 769152 failed

    18 décembre 2014, par prashanthp

    I am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i've used ffmpeg to convert in into a playable mp4 format.

    But sometimes it is showing error as x264 [error]: malloc of size 503008 failed

    What is the reason for this. Sometimes it's getting converted and sometimes it is showing error .

    Here is the console output.

  • ffmpeg wont encode h264 mp4 video with libx264 installed

    2 décembre 2014, par el producer

    I'm trying to do a simple encoding of an mp4 in h264 to mp4 but I keep getting the error:

    Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    I'm using this command: 

    ffmpeg -i qDqMvfoapXh6FO3KMuYiZCcG.mp4 out.mp4

    I have compiled and installed from the ffmpeginstaller 8.0 from http://ffmpeginstaller.com/

    This was working until i removed everything containing ffmpeg in the file name so that I can install libvpx and recompile ffmpeg. I used this command (as root) to remove all traces of ffmpeg from my system (redhat) 

     find / | grep -w ffmpeg | xargs rm -r -f
 find / | grep -w cpffmpeg | xargs rm -r -f
 find / | grep -w ffmpegscript | xargs rm -r -f

    Then I installed libvpx successfully and installed ffmpeg again but have not been able to encode h264 mp4 files since. Since them I have removed ffmpeg completely and recompiled a few times but haven't got it to work again.

    Complete ffmpeg output:

  • Compiling x264 on a Mac : "No working C compiler found" and "arm-linux-androideabi-gcc : command not found"

    29 novembre 2014, par Xavi Gil

    I am trying to compile the x264 library for Android, following this post.

    I have cloned the x264 project git clone git://git.videolan.org/x264.git and tried to compile with the following configuration:

    NDK=~/development/android-ndk-r10c    
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
PLATFORM=$NDK/platforms/android-21/arch-arm

./configure \
--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
--sysroot=$PLATFORM \
--host=arm-linux \
--enable-pic \
--enable-static \
--disable-cli

    The problem is that I get a No working C compiler found. error.

    The conftest.log output:

    $ cat conftest.log 
./configure: line 153: arm-linux-androideabi-gcc: command not found

    But the arm-linux-androideabi-gcc is the toolchain's bin folder!!

    Looking at this other question it looks like for some reason, even though the file exists, since it is a 64bit Mac, it won't execute the arm-linux-androideabi-gcc file and will return this weird error and log.

    I am in a Mac OS X 10.10 and I have installed the XCode Command Line Tools:

    $ xcode-select -p
/Applications/Xcode.app/Contents/Developer

    GCC version:

    $ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.0.0
Thread model: posix

    Can anyone tell me how to fix this please?

  • How to open AVCodec ?

    28 novembre 2014, par Anton Kasabutski

    I'm tired of searching the solution about this theme. Can anybody help?

    Types:

    AVOutputFormat* m_outFormat;
AVFormatContext* m_formatContext;
AVCodecContext* m_videoCodecContext;
AVCodec* m_videoCodec;

    Code:

    avcodec_register_all();
av_register_all();
m_outFormat = av_guess_format(NULL,filePath().toUtf8().constData(),NULL);
//filePath ended like ".mp4"
if (!m_outFormat)
    return; //all is fine
avformat_alloc_output_context2(&m_formatContext,NULL,NULL,filePath().toUtf8().constData());
m_formatContext->oformat->video_id = CODEC_ID_H264;
m_outFormat=m_formatContext->oformat;
////////////////////////////////////////////////////////////////////
m_videoCodec=avcodec_find_encoder(CODEC_ID_H264);
m_videoStream = avformat_new_stream(m_formatContext,m_videoCodec);
if (m_videoStream)
    return; //all is fine
m_videoCodecContext = avcodec_alloc_context3(m_videoCodec);
m_videoCodecContext->codec_id = CODEC_ID_H264;
m_videoCodecContext->width = 1280;
m_videoCodecContext->height = 720;
m_videoCodecContext->codec_type = AVMEDIA_TYPE_VIDEO;
m_videoCodecContext->pix_fmt = PIX_FMT_YUV420P;
av_codec_open2(M_videoCodecContext,m_videoCodec,NULL);

    I'm getting an error:

    [libx264 @.....] Codec type or id mismathes.

    av_codec_open2(..) returned (-22 error). Where I did mistake?More info:
    • last ffmpeg
    • Mac Os x 10.10
    • libx264 installed
    • after av_guess_format(...) I've got audio_codec = CODEC_ID_H264, video_codec = CODEC_ID_NONE, long_name MP4(MPEG-4 Part 14) in m_outFormat.
    • after avformat_alloc_context3(...) I've got audio_codec_id = video_codec_id = CODEC_ID_NONE in m_formatContext.
    • after avcodec_find_encoder(CODEC_ID_H264) I've got name = "libx264", id = CODEC_ID_MPEG1VIDEO in m_videoCodec.

      I can share more info if You can say, what do You exactly need.
