<div>Hi guys,</div> <div>I finally figured out how to play the rgb file:</div> <div><br>gst-launch-0.10 filesrc location=/snowboard-jum-352x288x75.rgb blocksize=304128 ! video/x-raw-rgb,width=352,height=288,depth=24,framerate='(fraction)'15/1,bpp=24,endianness=4321,red_mask=255,green_mask=65280,blue_mask=16711680 ! ffmpegcolorspace ! video/x-raw-rgb,width=352,height=288,framerate='(fraction)'15/1 ! ximagesink <br> </div> <div>if ffmpegcolorspace is nt mentioned the pipeline:</div> <div> <p class="MsoNormal" style="MARGIN: 0in 0in 0pt; mso-pagination: none; mso-layout-grid-align: none"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">gst-launch-0.10 filesrc location=/snowboard-jum-352x288x75.rgb blocksize=304128 ! video/x-raw-rgb,width=352,height=288,framerate='(fraction)'15/1 ! ximagesink & </span></p> <p class="MsoNormal" style="MARGIN: 0in 0in 0pt; mso-pagination: none; mso-layout-grid-align: none"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The video doesnt display correctly.</span></p> <p class="MsoNormal" style="MARGIN: 0in 0in 0pt; mso-pagination: none; mso-layout-grid-align: none"><span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"></span> </p></div> <div>What exactly does ffmpegcolorspace do ? there is no colorspace conversion reqd. (rgb is playable on ximagesink) - is it reqd for some bpp conversion( my display is configured to 16 bpp and the video is at 24 bpp)</div> <div> </div> <div>Thanks and Cheers</div> <div>Gaurav</div> <div> </div> <div><span class="gmail_quote">On 8/3/07, <b class="gmail_sendername">Gaurav Singh</b> <<a href="mailto:gausinghnsit@gmail.com">gausinghnsit@gmail.com</a>> wrote:</span> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div>Hi Stefan, Hi Tim,</div> <div>I tried the given pipeline and it worked after 1 modification.
