 Summary of the bug:

 Following command FAILS on tvOS (but exactly same code works on iOS):

 {{{
 avformat_open_input(&pFormatCtx, sdpString, NULL, &opts)

 where sdpString is

 "data:text/plain;charset=utf-8,v=0\r\no=- 0 0 IN IP4
 235.255.255.245\r\nc=IN IP4 235.255.255.245\r\nm=video 8008 RTP/AVP
 26\r\na=source-filter: incl IN IP4 235.255.255.245 192.168.68.94\r\no=- 0
 0 IN IP4 235.255.255.245\r\nc=IN IP4 235.255.255.245\r\nm=audio 8006
 RTP/AVP 0\r\na=source-filter: incl IN IP4 235.255.255.245 192.168.68.94"

 }}}

 How to reproduce:

 {{{
 - Compile FFMPEG for tvOS using this build script:
 https://github.com/kewlbear/FFmpeg-iOS-build-script/blob/master/build-
 ffmpeg-tvos.sh

 - Link with tvOS project

 - Run following commands on Apple TV
         avcodec_register_all();
         av_register_all();
         avformat_network_init();
         AVDictionary *opts = 0;
         pFormatCtx = avformat_alloc_context();
         avformat_open_input(&pFormatCtx, sdpString , NULL, &opts)
 }}}
