But it'll be great if any one can help.<br><br>Here's my problem: I need a program to encode video using h264 and mpeg4 codec in gstreamer, but seem gstreamer in ubuntu lacks of these encoder. I've searched google, tried some packages and tried to build the package from source code, too. With gst-ffmpeg source code, mpeg4 encoder is enabled by default but not h264, and although I tried some parameters to enabled h264 encoder, but all failed. So, is there any 1 know already built package(s) with these encoder or how to enabled h264 encoder to build it from gst-ffmpeg source code ?<br> <br>Thanks and best regards.<br> <br> trungnt</td></tr></tbody></table><br> <hr size="1"> <a rel="nofollow" href="http://us.lrd.yahoo.com/_ylc=X3oDMTFnYXY0dG83BHRtX2RtZWNoA1RleHQgTGluawR0bV9sbmsDVTExMDM0NjgEdG1fbmV0A1lhaG9vIQ--/SIG=11ka86nha/**http%3A//downloads.yahoo.com/vn/internetexplorer/" target="_blank"> Truy cập Mail nhanh hơn! </a><br> Yahoo! khuyến khích bạn nâng cấp trình duyệt lên Internet Explorer 8 mới, tối ưu hóa cho Yahoo!. <a rel="nofollow" href="http://us.lrd.yahoo.com/_ylc=X3oDMTFnYXY0dG83BHRtX2RtZWNoA1RleHQgTGluawR0bV9sbmsDVTExMDM0NjgEdG1fbmV0A1lhaG9vIQ--/SIG=11ka86nha/**http%3A//downloads.yahoo.com/vn/internetexplorer/" target="_blank">Tải tại đây!
