Streaming to a Flash Media Server using the rtmpsink element

[André Dieb Martins]

Hello,

I'm trying to stream a flv stream into a Flash Media Server using the following pipeline:

GST_DEBUG=2,*rtmp*:5 gst-launch -v videotestsrc ! videorate ! ffmpegcolorspace ! x264enc ! flvmux streamable=true ! queue2 ! rmtpsink location="rtmp://host/app/stream live=1"

This is the result: http://pastebin.com/utD1t4CE

My question is: how should I start debugging? I'm also wondering if the src caps of flvmux are okay.

Thanks in advance.

[André Dieb]

Oops, I'm sorry.

I forgot to mention the pipeline closes right after the last line of the

I've had some problems streaming to Wowza with rtmpsink. I've never
actually read the log on that particular problem, because I noticed that
streaming baseline h.264 "solves" the problem (actually just setting
b-frames to 0 does the same).

Could you try if setting "profile=baseline" or "bframes=0" on x264enc has
any effect?

Hello Ari-Pekak Viitanen,

Firstly thank you for the help.

Setting either one of the parameters you mentioned didn't had any effect. I
just discovered that the RTMP_Write() call on gstrmpsink.c line 258 is
raising a SIGPIPE signal, which is the cause of the abnormal shutdown.

Any idea?

Hello,

I am trying to stream audio + video by using rtmpsink.

My pipeline works well with raw audio + h264(hw accelerated) video
However if I use aac encoded audio(hardware accelerated) and h264(hw
accelerated) video it does not work.
I am trying to do over TI DM3730(omap3)

here is my pipeline :
gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=2 !
video/x-raw-yuv,format=\(fourcc\)UYVY ! TIVidenc1 codecName=h264enc
engineName=codecServer resolution=720x480 ! queue2 ! flvmux name=mux alsasrc
! TIAudenc1 codecName=aacheenc engineName=codecServer numChannels=2
samplefreq=44100 bitrate=44000 ! mux. mux. ! queue2 ! rtmpsink
location='rtmp://192.168.2.200/videochat/sankar'

However If I use ffenc_aac instead of TIAudenc1,its working fine.

Here is working pipeline:
gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=2 !
video/x-raw-yuv,format=\(fourcc\)UYVY ! TIVidenc1 codecName=h264enc
engineName=codecServer resolution=720x480 ! queue2 ! flvmux name=mux alsasrc
! ffenc_aac ! mux. mux. ! queue2 ! rtmpsink
location='rtmp://192.168.2.200/videochat/sankar'

What is going wrong?

please give suggestions.

Hi pratik,

I honestly don't know out of my head why it doesn't work, though I'm sure a
log dump with GST_DEBUG=3 might help :)

Just out of curiosity, which server are you using on rtmp://
192.168.2.200/videochat/sankar ? My attempts to stream using rtmpsink and
Flash Media Server did not work, showing a lot of errors on the FMS side.

Hello André Dieb,

I am streaming to wowza media server,
I found that h264+aac in flv container will not work,
so I am trying with h264+aac in mp4 container, its f4v file format.

Hi,

I had (probably) the same problem.

Add this caps filter after your faac entry :

audio/mpeg,mpegversion=4,stream-format=raw

Because flvmux only accept raw aac on his audio sink.

It solves my problem, hope it will solves yours too.
