[FFmpeg-user] Recipe to stream to Android

[Joe Kreidler]

I asked this question on the ffserver mail list, but there has not been
any responses. I'm trying the ffmpeg list since this list is more active
and I am not sure if my problem is in ffserver or ffmpeg.

I am trying to stream H264 video using ffmpeg and ffserver on a Ubuntu
12.04LTS desktop to an Android tablet running a small test client app
on Ice Cream Sandwich v 4.0.4. Note, I am not using ffmpeg or ffserver
on Android. I know my test client app is working properly because I can
successfully stream the following H.264 content.
rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

I know that the problem is that ffserver is generating the SDP for the
video media like this:

m=video 0 RTP/AVP 96
b=AS:128
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1
a=control:streamid=0

The format parameter line (a=fmtp) is missing the "sprop-parameter-sets"
and "profile-level-id" parameters and without these parameters, Android
does not accept the RTP data.  A valid line looks like this:

a=fmtp:96 packetization-mode=1; sprop-parameter-sets=Z0LAHukBQHsg,aM4G4g==;
profile-level-id=42C01E

My ffmpeg and ffserver configuration files are included below. If
someone has successfully streamed H.264 content to an Android tablet,
can you share you configuration me with?

Thank you in advance,

Joe


I captured a video on the Android device and played it back just
to verify that I had a good video file. I then transferred the file to
my Ubuntu desktop. I send the video content to ffserver using the "copy"
codec, in other words, no transcoding of the content at all.
