  • ffmpeg on windows mobile with C#

    19 septembre 2017, par Riv

    I need to work with FFmpeg for windows mobile with C#, in fact I want build player for .m4b,.m4a files. I know that the TCPMP is exist, but I want to make my own.
    So I want to use .Net, and I have some questions :

    1. If I use some C# FFmpeg wrappers, for example TaoFramework, will it work on windows mobile(in case if I use FFmpeg lib compiled for windows mobile) ?

    2. In FFmpeg wiki I found this

    Once you have compiled, or downloaded,
    the Windows DLLs for FFmpeg, you can
    use .Net Platform Invoke (PI) to
    access the functions in the libraries
    libavformat and libavcodec.
    Link to source...

    But I don’t know how can I use it ? I tried to make it with dll that I had downloaded from http://ffmpeg.arrozcru.org/autobuilds/. Maybe I need to compile ffmpeg by myself for this option ?

    And last question is - what is libavcodec ? When I downloaded shared build, I got avcodec-52.dll, avfilter-1.dll, ffmpeg.exe, but I coudn’t find libavcodec.dll, or it’s just alias ?

cd libvorbis-1.3.5
    
./configure --prefix="$HOME/ffmpeg_build" --with-ogg="$HOME/ffmpeg_build" --disable-shared
    
make
    
make install

    i get this error with command make

     #include <ogg></ogg>ogg.h>

    Thanks

  • Using ffmpeg to encode web dash and audio drift

    1er octobre 2016, par John Joske

    I’m trying to use ffmpeg to create webm-dash encoded files from a usb web cam. Adapted from this example http://wiki.webmproject.org/adaptive-streaming/instructions-to-do-webm-live-streaming-via-dash

    I have managed to get something nearly works with the following command :

    ffmpeg -f video4linux2 -framerate 30 -s 640x360 -i /dev/video0
    -thread_queue_size 512 -f alsa -ar 44100 -ac 2 -i hw:2 -map 0:0 -pix_fmt yuv420p -c:v libvpx-vp9 -s 640x360 -keyint_min 60 -g 60 -speed 6 -tile-columns 4 -frame-parallel
    1 -threads 8 -static-thresh 0 -max-intra-rate 300 -deadline realtime
    -lag-in-frames 0 -error-resilient 1 -f webm_chunk -header video_360.hdr" -chunk_start_index 1 video_360_%d.chk -map 1:0 -c:a libvorbis -b:a 128k -ar 44100
    -f webm_chunk -copytb 1 -audio_chunk_duration 2000 -header video_171.hdr -chunk_start_index 1 video_171_%d.chk

    However over a period of time the audio chunks slowly get behind the video chunks, can anyone suggest a way to ensure they stay the same.
