I found my problem and the solution was very easy. All I had to do was add the following line to my ffserver configuration file.
AVOptionVideo flags +global_header The “flags +global_header” info is used to force ffmpeg to spit out some important specifications in the SDP it generates. ffmpeg places global headers in extradata instead of every keyframe. WITHOUT the global_header flag, the SDP returned to the Android tablet by ffserver is: v=0 o=- 0 0 IN IP4 127.0.0.1 s=No Title c=IN IP4 0.0.0.0 t=0 0 a=tool:libavformat 54.59.106 m=video 0 RTP/AVP 96 b=AS:128 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1 a=control:streamid=0 With the global header specification, the SDP returned to the Android tablet by ffserver is: v=0 o=- 0 0 IN IP4 127.0.0.1 s=No Title c=IN IP4 0.0.0.0 t=0 0 a=tool:libavformat 54.59.106 m=video 0 RTP/AVP 96 b=AS:128 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1; sprop-parameter-sets=Z2QAHqy0BQHtCAAAAwAQAAADA7B4sXU=,aM8yyLA=; profile-level-id=64001E a=control:streamid=0 Android will not accept the SDP without the sprop-parameter-sets and the profile-level-id attributes being present.
