<body class='hmmessage'><div dir='ltr'><br><div>> I've seen this bug report from November 3<br>> <br>> Ticket #12531: vdpau segfaults when video dimensions not multiple of 16<br>> <br>> and assume that it -is- a bug, and that the dimensions may be more<br>> tightly specified, but how tightly does the spec claim? I haven't<br>> been able to figure this out. (I know that myth != spec, but assume<br>> that, modulo bugs, adhering to the spec is good enough.)<br>> <br>> I don't [yet] have a VDPAU implementation to test against, but I'd<br>> like to not be unpleasantly surprised later if I happen to pick bad<br>> crop values. I'd also like to not crop way more loosely than I<br>> otherwise might want to.<br>> <br>> Thanks.<br><br>Hi, <br><br>I am the creator of this bug report, and I cannot verify anything code related, but the problematic behaviour is persistent on my system.<br>The segfault seems to occur in the libvdpau_nvidia.so.352.41 library, as shown in the ticket, so I don't know if it's mythtv's or nvidia's problem. Vlc has no problem, though.<br><br>I use handbrakecli to transcode recordings/videos and I've updated the command with "--loose-crop 15 --modulus 16", which avoids the problem by cropping no more than 15 pixel lines.<br><br>I don't know if it's even possible, but it would be ideal if mythtv could check the frame size before feeding it to vdpau and crop it accordingly.<br><br>Yianni.<br><pre class="wiki"><br></pre></div> </div></body>
