Get RV24 with imem from Intel RealSense camera and broadcast it
Posted: 28 Nov 2016 09:35
Hello, I'm trying to broadcast segmented frames from RealSense SR300 camera. I'm using imem module to input segmented frames in RV24 but get nothing. I have used parts of code for imem callbacks from here https://forum.videolan.org/viewtopic.php?t=122178
Here is my code:
I think this code should give me window with image from realsense camera but i get nothing.
Here is the log:
Here is [03153f1c] core input debug: `imem://' successfully opened but there are neither errors nor image. What is my mistake? How to look for errors?
Here is my code:
Code: Select all
uint8_t * buffertobroadcast;
buffertobroadcast = (uint8_t*)malloc(640*480*3);
memset(buffertobroadcast, 10, 640*480*3);// put something into buffer until realsense camera put here frames
int mNumInputs = 1;
int mSampleFreq = 25;
char *vlc_args[12];
vlc_args[0] = "-vvvvv";
vlc_args[1] = (char*)calloc(200, 1);
sprintf(vlc_args[1], "--imem-get=%ld", myImemGetCallback);
vlc_args[2] = (char*)calloc(200, 1);
sprintf(vlc_args[2], "--imem-release=%ld", myImemReleaseCallback);
vlc_args[3] = (char*)calloc(200, 1);
sprintf(vlc_args[3], "--imem-cat=2"); //CAT 1 == AUDIO
vlc_args[4] = (char*)calloc(200, 1);
sprintf(vlc_args[4], "--imem-data=%ld", buffertobroadcast);/** my context custom data to be passed callbacks **/
vlc_args[5] = "--imem-id=0";
vlc_args[6] = (char*)calloc(200, 1);
sprintf(vlc_args[6], "--imem-codec=RV24"); //CODEC, format of the data passed to vlc in the buffers
vlc_args[7] = (char*)calloc(200, 1);
sprintf(vlc_args[7], "--imem-width=640");
vlc_args[8] = (char*)calloc(200, 1);
sprintf(vlc_args[8], "--imem-height=480");
vlc_args[9] = (char*)calloc(200, 1);
sprintf(vlc_args[9], "--imem-channels=%d", mNumInputs); //number of channels
vlc_args[10] = (char *)calloc(200, 1);
sprintf(vlc_args[10], "--imem-samplerate=%d", mSampleFreq); //sample frequency
//vlc_args[11] = "--imem-fps=2.000000";
libvlc_instance_t * inst;
libvlc_media_player_t *mp;
libvlc_media_t *m;
/* Load the VLC engine */
inst = libvlc_new(11, vlc_args); // запуск VLC с аргументами для imem
m = libvlc_media_new_location(inst, "imem://"); // проигрывать из памяти
mp = libvlc_media_player_new_from_media(m);
libvlc_media_release(m);
//libvlc_vlm_add_broadcast(inst, "strm", "imem://", "#transcode{vcodec=mp1v,vb=800}:standard{access=http,mux=mpg,dst=127.0.0.1:8080}", 0, NULL, 1, 0);// broadcasting didn't work so i comment it and tryed to play the frames in window
//libvlc_vlm_play_media(inst, "strm");
libvlc_media_player_play(mp);
//realsense stuff to fill the buffer in "while()" cycle until program not closed
libvlc_media_player_stop(mp);
/* Free the media_player */
libvlc_media_player_release(mp);
