Hi ,I want to open audio and Screen grab devices in my application ( will
encode and mux them into an output video) like this
AVInputFormat *ifmt=av_find_input_format("gdigrab");
if(avformat_open_input(&pFormatCtx,"desktop",ifmt,&options)!=0){
printf("Couldn't open input stream.\n"); return -1; }
//INPUT TO CAPTURE AUDIO AVInputFormat
*ifmtAudio=av_find_input_format("dshow");
if(avformat_open_input(&pFormatCtxAudio,"audio=MicroPhone (Realtek Hight
Defini",ifmtAudio,NULL)!=0){ printf("Couldn't open input audio
stream.\n"); return -1; }
but the audio is failing to open .Is this even the right way to open them if I
plan to mux encoded streams later .This question is part of a program here:
