MX53/GStreamer/RTP Streaming

PlartiNuhtl — Mon, 30 Jan 2012 17:24:46 GMT

Hi.

Did anyone ever successfully try streaming from/to the MX53?

My pipelines:

Source:

(on the MX53)

gst-launch mfw_v4lsrc ! mfw_ipucsc ! mfw_vpuencoder codec-type=std_mpeg4 ! r
tpmp4vpay ! udpsink host=192.168.1.52 port=5000 sync=false

This works and I can display this stream on a ubuntu desktop machine.

Sink:

(again MX53)

gst-launch \
udpsrc port=5000 caps="application/x-rtp,clock-rate=90000" \
! gstrtpjitterbuffer latency=0 ! rtpmp4vdepay \
! "video/mpeg, mpegversion=4, width=720, height=576, framerate=15/1" \
! mfw_vpudecoder ! fakesink -v --gst-debug=mfw_vpudecoder:4

This does not work. The problem is the mfw_vpudecoder plugin. In the debug log I see:

0:00:05.703612111 1336 0x126428 ERROR mfw_vpudecoder mfw_gst_vpu_decoder.c:2108:mfw_gst_vpudec_vpu_init: >>VPU_DEC: vpu_DecGetInitialInfo failed. Error code is -1 handle 1326488

0:00:05.704250861 1336 0x126428 DEBUG mfw_vpudecoder mfw_gst_vpu_decoder.c:3109:mfw_gst_vpudec_chain: >>VPU_DEC: mfw_gst_vpudec_vpu_init failed but with MPEG2 keep asking for more data timeouts=0, init fail cnt=1

Setting the parser option of the mfw_vpudecoder plugin does not help. Using mpeg4videoparse does not help either.

Can somebody give me a hint?

Hi Plarti,

I am using VLC as streaming platform and I can say it works perfect when the QSB is streaming data outward to a PC.

But I still have issues to stream in FullHD from a PC to the QSB (using VLC on both QSB & PC). I suceeded only with a very low resolution, low framerate mp4 file.

Using gstreamer, I get error as well with mfw_vpudecoder. Did you try another decoder?

Hi, Rodrigu,

Can you please introduce your example for video streaming from QSB to PC.

Thanks a lot.

Chaim.

Also interested in this stuff and will implement something similar in the future.

Checking this thread for some inputs.

Rodrigue,

How did you get VLC accelerated (by VPU)?

Plarti,

Can you movie be played locally by vpudecoder? (is its codec supported?)

Re: MX53/GStreamer/RTP Streaming

Rodrigue — Fri, 11 May 2012 15:29:48 GMT

Hi Diaine,

I did not get VLC accelerated by the VPU. The only thing I succeeded to do was to stream from QSB to my PC. PC to QSB works with very resolution/framerate ( because not HW accelerated).

AFAIK, VLC uses its own implemented codecs and we can therefore not link it with our codec libraries (at least in its current state, we do not have this freedom).

Hi Rodrigue, thanks a lot for your reply.

Hi all,

Is there any other player, other than VLC, which can help in the streaming from PC to i.MX5X ?

Re: MX53/GStreamer/RTP Streaming

daiane_angolini — Mon, 14 May 2012 15:52:36 GMT

What do you mean?

Do you want another player to be used on imx side or PC side?

I like to use gstreamer for the imx side.

What is your source codec type? are you sure your camera output match the example?

Chaim.

If you make a movie, using your USB web camera. The movie will be H264? Or it will be a MPEG4?

What´s the codec type for your video src?

Re: MX53/GStreamer/RTP Streaming

BrilliantovKiri — Sun, 20 May 2012 08:56:45 GMT

Hello, Chaim A!

For USB-camera you must use v4l2src.

can you please explain in brief..what is the procedure to update gstream packages..???

Re: MX53/GStreamer/RTP Streaming

BrilliantovKiri — Mon, 28 May 2012 12:22:12 GMT

Bhavana, you can build packages from source or use package manager. For Ubuntu you can use next sequence - apt-get update && apt-get upgrade.
