Hi, BugMaster<br><br>Thank your reply.<br><br>I run the program on winxp. I compile the x264 by using vs2005. So I must make small changes to compile successfully in vs2005. I used this method to encode i420 csp all the while. Everything is well. <br>
<br>Today I do the test on the linux. I compile and run my changed program. The result is same as on windows. But everything is ok when I compile and run the unchanged program.<br><br>I realize the program return error message because I changed something for encoding i422 csp. I will analyse the reason next.<br>
<br>Thank you very much.<br><br>Tian<br><br><br><br><div class="gmail_quote">2011/12/2 BugMaster <span dir="ltr"><<a href="mailto:BugMaster@narod.ru">BugMaster@narod.ru</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

Hi. I doubt this have anything todo with order in x264_cli_csps<br>
because for every element there is explicit position constantant and<br>
so reodering shouldn't change real order. Also I tried your<br>
commandline with the current version (r2106) without swscale support<br>
and didn't get any errors so you probably messed up something in<br>
commandline first time (there are doubtful params there like<br>
resolution with and without --input-res) and then fixed it so all<br>
become correct.<br>
