DM3730 gstreamer video resizing issue

Other Parts Discussed in Thread: DM3730

Hi everybody  ,

video to be played  is  640x352   MPEG4  ,  on DM3730

if  I  launch gstreamer using  :


gst-launch filesrc location=/home/root/videos/FlashForward_tagliato.avi ! avidemux ! queue ! TIViddec2 ! TIDmaiVideoSink

what I can see on my display is  video playing but with a black area  just  under the video ( you can see it if your background is not black ) .

It seems  resizing  is wrong  .

if you play  same command on a PC  no issue at all  (  on PC no TI  codec  is used  ... )

if  I use  same  video with Mplayer ( ARM only based )  it works no issue .

what can I set in the gstreamer command to make it play right ? where am I wrong ?

I can provide offline a video showing the issue .

bye

Carlo

              Could you please share the video to me. Also please let us know what is the DVSDK version you are using.

    Best Regards

    Carlo,

    Can you try playing a stream whose native resolution is 640x480(VGA) ?

    If this plays fine, then I'd suspect that a VGA setting is hardcoded somewhere.

    Carlo,

              After further analysis, The auto resize does not happen with the above pipeline, As the LCD resolution is 640x480 & the stream you are playing of 640x352, then the for the height of 128 (480-352) pixels you will be seeing black bar. I think this is expected behavior.

             Also resizing of the stream you are using would become wrong aspect ratio, so that might not be right choice.

             I am checking in gstreamer how to enable resize in case required.

    Best Regards,
