  • How to integrate shared object file of libx264 while using ffmpeg for android ?

    5 août 2014, par user3665376

    I am working with integrating ffmpeg for android .

    Since I needed H.264 encoding I need to integrate libx264 with ffmpeg . Given below are the steps I followed .

    1) Build the latest libx264 using android compiler tool-chain to obtain libx264.so.142 .

    2) Build ffmpeg v 2.3 referring to this with —enable -libx264 option while configuring ffmpeg . The method explained in the blog included some editing in configure file of ffmpeg to generate shared object files with extension format [lib name].so rather than the generating shared object file with extension format [lib name].so.[version] (Since android build system supports files with extension .so only).

    The building process was successful but since the generated .so files (after building ffmpeg) has dynamic dependency with libx264.so.142,I need to package libx264.so.142 also with the android .apk file . But since the above format (.so.142) is not supported with android apk building system I cannot package it with the .apk .

    So I think the only option I have is to make some changes in configure file of ffmpeg to change the dynamic dependency of libx264.so.142 to libx264.so . Am I right ??

    What changes do I need to make to ffmpeg configure file to achieve this ?

  • Text overlay on ffmpeg live stream rtmp output [duplicate]

    20 décembre 2017, par Ricky

    This question already has an answer here :

    I have ffmpeg take an HLS stream and output into an rtmp url with this command.

    ffmpeg -re -i "http://184.72.239.149/vod/smil:BigBuckBunny.smil/playlist.m3u8" -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 6000k -vb 400k -maxrate 1500k -deinterlace -vcodec libx264 -preset veryfast -g 30 -r 30 -f flv "rtmp ://ingest-us-east.a.switchboard.zone/live/moo-abced-ppoo-noas"

    I would like to put text overlay on the stream but I can’t figure out how to do it. I need to have the the ability to control when the text comes up on the screen. Your help is much appreciated.
