Thank you so much!

I saw this post before but missed the small "tr48.avi" link at the top of the e-mail. I have the file now.

Thank you again!

I have a follow-up question about this -- how can you get the tr48.avi file posted by Juan Gonzales? I've installed gstreamer on the DM6467 on top of the 2.00.00.22 SDK and can play elementary files with it. I'm now looking for an avi file that works well with it (I've run into issues with the .avi files I've generated myself and want to start with a known baseline). If anyone could help with this, that would be great!

whoops, answered my own question. I was able to strip out the elemental video from the ArcSoft created .avi file with ffmpeg, plays fine in the standard decode demo.

Vim Venture — Mon, 15 Jun 2009 16:30:03 GMT

I found that I had to convert the audio from .avi files created with the Arcsoft tool from uLaw encoding to mp3. I used ffmpeg to do this. Then the .avi with mp3 audio played in Gstreamer on the DM355.

A problem I am facing:

I have not been able to strip the elementary mpeg4 video out of that same .avi file. I want to play my own content in the decode demo, not Gstreamer. I've tried copying the elemental video to a separate file with ffmpeg, but the format is not right for the decode demo. Has anyone had any luck with that?

Thanks!

Thank you, Juan Gonzales

I tried export CAIRO_LIBS=/usr/lib/libcairo.so

Has been a success.

Thank you for your help

Are you sure cairo is the full name of the library? Can you find it in your filesystem?

not having done this before, perhaps Alex or yangsb will be able to provide more specific advice.

I know certain versions of Gstreamer support RTP, but to be honest I am not up to speed on this. Perhaps the following link will help

http://gstreamer.freedesktop.org/documentation/rtp.html

Juan,

Do you Know any way to use the GStreamer getting video stream from RTP (or anyone) network protocol?

Re: How does one convert a video file into a DM355 mpeg4 decoder format?

Juan Gonzales — Tue, 25 Nov 2008 20:21:24 GMT

Alex,

I believe the user application is overwriting the window position set via bootargs. Assuming you are using gstreamer port mentioned earlier in this post, I have the following feedback from one of our experts

"It is possible to play the video in the center of the screen. There is an undocumented option. (I did not get time to document this feature yet.) But the fbvideosink plugin should be modified a little bit to do so.

If you look at script gst.sh carefully, you could find line 37 is

queue ! vdec engine=GstEngine codec=1 pad-buf-alloc=true ! fbvideosink

By changing pad-buf-alloc from true to false, fbvideosink will use EDMA to copy the encoder output buffer to framebuffer. So fbvideosink should be modified so that destination memory address of EDMA-copy should be pointed to the proper location instead of the start address of the framebuffer. The dest address offset could be calculated by the screen resolution and video resolution.

To use this feature, in VGA case, the bootargs should not be set to 640x480, (because the shift is caused by fbdev driver, not by gstreamer), bootargs should be set no less than D1 resolution."

Re: How does one convert a video file into a DM355 mpeg4 decoder format?

xalexandregr — Tue, 25 Nov 2008 17:18:58 GMT

Juan,

When I set bootargs with this string below, what means, in the practice, the 0,0 in '2025K@0,0'? I know that it is the window coordinates. So, I think that I set 40,0 (2025K@40,0) I am shifting in 40 pixels the window to the right, but it's not working when I try ./gst.sh 3 video.avi.

"video=davincifb:vid0=720x480x16,2025K@0,0:vid1=720x480x16,2025K@0,0:osd0=720x480x16,1350K@0,0:osd1

=720x480x4,1350K@0,0"

My idea is to set the frame buffer like 720x4800x16,2025K@40,0 to centralize the video in the middle of the screen because the video resolution is 640x480. Is it right?

I need put the video in the resolution 720x480 to play in the SDTV mode NTSC. How can I do this? It's not possible using the MediaConverter by ArcSoft. Are you from TI attacking this solution?
