• FFMPEG API : How to connect to RTSP stream using av_open_input_file ?

  10 novembre 2011, par Alex

  I'm trying to connect to some RTSP stream using av_open_input_file() like this :

  AVFormatContext* ic;
avcodec_register_all();
av_register_all();
av_open_input_file(&ic, "rtsp://login:password@xxx.xxx.xxx.xxx/videoinput_1/mjpeg/media.stm", NULL, 4096, NULL);

  It always returns 'file not found'. The same url, though, I can see in, say, VLC player. Do I do something wrong in my code ?

  I'm using FFMPEG 0.6, shall I use the latest instead ?

• AndroidBitmap_lockPixels always failing

  20 septembre 2017, par Hadj Ali Oussama

  In my jni module I copy images to bitmaps, which were previously
  passed from my java application.

  I do this using AndroidBitmap_lockPixels/AndroidBitmap_unlockPixels.
  Basically, it renders the image correctly, but there’re strange
  effects : sometimes the application gets stuck, or after some time
  AndroidBitmap_lockPixels always returns -3

  (ANDROID_BITMAP_RESULT_ALLOCATION_FAILED). I guess this is because I
  update these bitmaps not from the GUI thread, isn’t it ?

  If so, what would be correct way to "post" this operation to the GUI

  thread ? Is it possible in jni ?

  Thanks.
