  • 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.

  • Webrtc to rtmp using ffmpeg for live streaming from webcam to browsers and mobile

    6 février 2017, par Omar Suleiman

    I am new in live streaming, and i am working on the website to allows user to broadcasting and visitors can watch and listen the video, I use webrtc from webcam and the url is blob, so I can not find the best way to transcode webrtc to rtmp or hls to show the live streaming in the browsers as a flash and on mobile as hls. I dont know from where can i start.

    what is the best way for transcoding (ffmpeg or red5 or nginx or what) - like : 1 broadcaster to 1000 viewers can watch and listen and there is many broadcasters also.

    what about CPU usage.

    I am used asp.net MVC

    your help is very appreciated.
    Thanks.

  • How to build FFMPEG lib with android ndk

    27 janvier 2017, par S. Le Galloudec

    I introduce my problem : I’m a student working on a project asked by a company to my school.
    My part is to develop an android application (i have to use c++) who can make an authentication, ask to an api wich camera the client can watch, then display in real time the stream of the IP camera (using RTSP protocol)

    To be honnest i’m pretty lost. I’ve found the library FFMPEG, wich looks like useful to my project. If i got it right, the library can display a stream from a camera. So i built the library for my project, and then i tried to include it in my program.

    I did it the same way i did to include the library curl that i already use.

    But when i try to run my program, i got this message :

    FAILURE : Build failed with an exception.
