[gst-devel] RTMP streaming in web page

[Marco Ballesio]

Hi,

sorry for the late reply. I grasped only now that you're using a
custom (hardware-specific) encoder. It should not matter as long as it
sends the parameters set to the payloader within the "codec-data"
field (you can check through the caps negotiated bw encoder and
payloader), so check whether it's a configurable option if not
enabled.

Said so, the behaviour of both the clients (GStreamer and VLC) is
expected, because their decoders never get an essential piece of
information that is the configuration data. As it appears such an
information is never re-sent from the payloader (even with
send-config=true config-interval=2) the most plausible cause is the
one I wrote in the paragraph above.

As a note, the following pipelines work correctly on my old eeepc:

gst-launch v4l2src ! \
video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! \
ffmpegcolorspace ! ffenc_mpeg4 ! rtpmp4vpay \
send-config=true config-interval=2 ! udpsink host=127.0.0.1 port=1234

gst-launch udpsrc port=1234 ! \
"application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP4V-ES,
payload=96" ! \
rtpmp4vdepay ! ffdec_mpeg4 ! xvimagesink

in case your encoder does not have an option to encapsulate
parameter-sets into the src caps, it's still possible to use a parser,
that is the sending pipe should be modified as follows (note the stub
for the encoder name):

gst-launch v4l2src ! \
video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! \
ffmpegcolorspace ! your_encoder ! mpeg4videoparse ! rtpmp4vpay \
send-config=true config-interval=2 ! udpsink host=127.0.0.1 port=1234

I hope this will help.

PS next time you copy/paste debug output, please remember to disable
output color with something like:

export GST_DEBUG_NO_COLOR=1

Regards
