  • FFmpeg create output directory hierarchy

    31 janvier 2019, par David

    Recently bought an ip-cam which outputs a RTSP stream. I’m using the segment option of FFmpeg to create 60 minute long recordings.

    I want FFmpeg to write the files to a directory based on Year/Month/Date, and write to a file Hour-Minute.mp4 For example :
    /raid1/homes/share/public/recordings/queue/bedroom/2017/04/23/13-05.mp4 for a recording started on 23 april 2017, 13:05.

    Unfortunately FFmpeg seems to not create the directory hierarchy. FFmpeg quits since the directory can not be found.

    Input #0, rtsp, from 'rtsp://192.168.1.240/unicast':

    Can FFmpeg create output directories on the go ?

  • Apply filters to video while preview and save it with applied filter and original audio in android

    11 juillet 2016, par Rajkumar

    Dear geeks i m newbie to video processing. i want to apply a filter to a video at runtime, and i want to save that video after filter applied.
    Regarding this i m doing a research. I has gone through many libraries but i m struggling to achive my aim.

    Developement environment

    Migw-64 with windows 7 64 bit
    Android Studio 2.1 preview 5
    heap space 4GB
    com.android.tools.build:gradle:2.1.0
    android-ndk-r12-win-x86_64
    com.android.tools.build:gradle-experimental:0.7.0 —> to build NDK

    I have tried

    1)AndroidFastImageprocessingLibrary

    Chrisbatt -> AndroidFastImageProcessing in github
    github.com/chrisbatt/AndroidFastImageProcessing
    This library use GLSurfaceview to display filters but we could not save it to mp4 file

    so i found another implementation of it
    icmobilelab -> AndroidFastImageProcessing in github
    github.com/icmobilelab/AndroidFastImageProcessing/blob/master/framework/FastImageProcessing/src/project/android/imageprocessing/output/VideoFileEndpoint.java
    This library use JavaCV with ffmpeg compiled. But it failed.

    2)JavaCV
    JavaCV use outdated ffmpeg and it abondond

    3)Grafika -> in github
    github.com/google/grafika
    I tried Android Fast Image Processing with RecordFBOActivity in grafika. But i m failed. This library use MediaRecorder to record the contents of GLSurfaceView. But it records video without audio(I have tested the RecordFBOActivity and analyze the code )

    4)filter packs in platform_frameworks
    github.com/android/platform_frameworks_base/blob/master/media/mca/filterpacks/java/android/filterpacks/videosink/MediaEncoderFilter.java
    its android 4.2 edited core. i can’t run this code because too many jni dependencies.

    5)ffmpeg
    github.com/guardianproject/android-ffmpeg
    i tried ffmpeg3.1 compilation procedure implemented by guardianproject. it successfullay built a static library but i cannot build dynamic library( so files). i m stuck with a linker error. I think the linking order matters. i tried the linking order specified in below link
    https://fritzone.wordpress.com/2010/05/11/link-with-static-ffmpeg/
    but it won’t help. the following error occurs

    6)MediaCodec, MediaExtractor,MediaRecord,MediaMuxer
    finally i planned to combine AndroidFastImageProcessing with MediaCodec, MediaExtractor,MediaRecord,MediaMuxer.
    so i try to Extract audio from video using mediamuxer
    https://gist.github.com/sayan801/9a39ccad0818d2b3499a
    I use mp4 video (MIME Type video/avc that have 2 tracks audio and video) to extract audio
    but the resultant file is corrupted (just 4 kb)

    I think this question is another view of the existing problem
    if anybody experienced this problem please guide me
    Thanks
