Thank you very much for your answer. Unfortunately, this returns the error<br>
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin:decodebin0/GstTypeFindElement:typefind: Could not determine type of stream<br>
Is there anything else I can try?<br>
<br></blockquote><div><br>I would focus on just trying to play it first. I tried the first file, akiyo.yuv with a few different programs to no avail. It doesn't have any header info as it appears to just be raw video data. You could try setting a capsfilter with different caps, i.e.<br>
gst-launch -v filesrc ! video/x-raw-yuv, .... ! decodebin ! xvimagesink<br>but i'm not sure how this will work since I don't think the files have a fourcc.<br><br>Good luck,<br>Tristan<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

Try:<br>
filesrc ! decodebin | ffmpegcolorspace | theoraenc | oggmux | filesink<br>
<br>
decodebin is an element to "Autoplug and decode to raw media"<br>
