I checked the plugins related to h264 installed on my computer, they are h264 parser and rtph264pay and rtph264depay. There is no h264 decoder that I can use directly. Then, I googled “gst-libav” and got it installed on my computer. Now I have vdpauh264dec, but I still have no clue to get it work with h264 files. And when I try to play “mov” or “mp4” file with gst-launch playbin, the fault “h264 decoder missing” came up. Why is it????<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Can anyone help me with this please? <o:p></o:p></span></p><p class=MsoNormal style='text-indent:5.25pt'><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>With Regards<o:p></o:p></span></p><p class=MsoNormal style='text-indent:5.25pt'><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Gavin <o:p></o:p></span></p></div></body></html>
