Rebroadcast an RTP stream as an RTSP stream with Live555?

[Suneet Shah]

Hello,

I'm wondering if Live555 media server can help me accomplish the following:


- I'm using gstreamer to create a live video feed encoded in H264, and
then transmitted as RTP packets.
- I need to rebroadcast this stream as RTSP with a properly generated SDP
file, so that it can be viewed on Android


Can Live555 accomplish this? From the website, I couldn't tell if it works
well with live streams, or only with recorded files.

If so, can someone share an example SDP file or provide more instructions on
how to do so?

Thanks in advance,
Suneet

The supplied code includes demo applications that stream from files;
however, these can be adapted to stream from a live source instead.

Because your input data is a RTP stream, you could use a
"H264VideoRTPSource" as your 'input device'.

BTW, if you wished, you could also use our code (instead of
'gstreamer') to stream encoded H.264 video via RTP.

Thanks a lot Ross.

Can you confirm that others have had success streaming to Android with H264? Android seems extremely particular about RTSP implementations.

I'm using gstreamer to capture a desktop as live video. I can feed it to Live as raw video or encoded-- my goal is to get very low latency so I will try both.

I can also use ffmpeg to create the video stream if others have had success with the combo of ffmpeg and live.

No, it's up to 'others' to report any problems that they may have had
with Android clients playing streaming from LIVE555 servers.

The only such report that I've seen so far was one - last Sunday -
that claimed that an Android RTSP/RTP client did not handle the
static RTP payload type 33 (meaning: MPEG Transport Stream data). I
responded, pointing out that this client was not standards-compliant,
and needed to be fixed.

Nevermind-- apparently I was using a video resolution that would not work
with Android.

I tried again using a new .264 file with a lower resolution (320 x 240)---
and it works.

Hi Ross,
- .264 file (stream plays in VLC)
- .m4e file (stream plays in VLC)
Neither of these play on Android. Unfortunately, Android only supports H264
in an MP4 or 3GPP container.
Is there a way to stream this with Live555? When I tried streaming an mp4
file (e.g. H264 In MPEG4), it did not work.. Unfortunately, Android only has
native support for H.263/264 in MPEG4/3GPP.
Thanks,
Suneet
