I'm trying to develop an application able to receive mp4 streams from
the network using gstreamer but I'm  lacking on pipeline elements. I've
done some test and what i get is this:


gst-launch-0.10 filesrc location=/home/jsantos/Desktop/Vídeo023.3gp ! 
ffdemux_mov_mp4_m4a_3gp_3g2_mj2 name=d d. ! queue ! ffdec_h263 !
ffenc_mpeg4 ! rtpmp4vpay ! udpsink host= port=9090 d.

(I know, I'm complicating but in the middle of so many tries this is
what have in my console buffer :) )

Nokia 800

gst-launch-0.10 udpsrc port=9090 ! application/x-rtp,clock-rate=90000 !
rtpmp4vdepay ! hantro4100dec !  xvimagesink 
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element /pipeline0/hantro4100dec0: Could not decode stream.
Additional debug info:
gsthantro4100dec.c(1059): gst_hantro_4100_dec_chain ():
unsupported bitstream
Execution ended after 8659760000 ns.

Shouldn't hantro4100 be able to handle mpeg4? Also tried with h263p and
got the same problem. Wasn't able to use h263 since there is no

Best regards,
