<br>First off....Thanks for the replies.<br><br><br><div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">> The standard way to add options is a field in x264_param_t.
</blockquote><div><br><br>Nice one. Thanks.<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">><br>> But before you continue, is such a patch even needed anymore? iirc
<br>> recent PSP firmwares don't have gratuitous format restrictions. I<br>> won't accept a workaround for something that Sony has already fixed.</blockquote><div><br><br>I should have been more specific. I am looking to create 480x272 (
i.e. native res) video streams for playback with PMPMod AVC on the PSP. This is the encoding / playback method of choice for anyone who uses the PSP for regular video watching. It's the /only/ thing I use my PSP for. :) (approximately 80 minutes a day commute time)
<br><br>The difference compared to 320 x 240 is nothing short of astouding, especially at high resolutions.<br><br>I checked the differences again today. For the first pass, FPS in mencoder were 140 on average v's 68 in the source tree that I patched. This is with 5 threads v's 3 (above 3 caused stability problems for me before) on a quad core processor.
<br><br>2nd pass encodes were also limited to 1 thread. I'm unsure if this is still the case.<br> <br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
> And even aside from that, did PSP compatibility require any changes<br>> to the video stream, or only to the MP4 muxing? If it's just<br>> muxing, then having support in x264 won't help, because x264<br>

<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">As far as I'm aware, PSP firmwares _used_ to require some specific<br>MP4 atom, much like the iPod 640x480 'profile' does now though not as
<br>deeply hidden away. In current times (and I've had this tested by a<br>PSP owner running a recent official firmware) this atom is no longer<br>required and the only things needed are resolution, profile, level<br>
etc restrictions that should all be handled outside of x264.</blockquote><div><br><br>If there's some way that I can get 480x272 using the standard x264 svn code, I'm all ears. :) <br><br>I did hear talk some time ago that Sony would unlock 480x272 because their film sales for the PSP were terrible, but with a 2 month old baby, I confess that I haven't kept track of developments in the PSP world.
<br> </div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Before anyone jumps in to say 'could iPod 640x480 compatibility be<br>added?' there's no real need for that either as it's just a case of
<br>adding the required atom for iTunes to accept the file for<br>synchronisation to the iPod. This can be done with other tools<br>(Atomic Parsley). Otherwise just stick to the restrictions and the<br>file will be fine. You can even not bother with the atom and use some
<br>third party software to transfer the files if you like. I've been<br>told the iPods themselves are less picky than iTunes.<br><br>Rob<br><br>PS - <shameless website plug> If you want info on the restrictions
<br>(and how to encode working files from FFmpeg) you can take a look at:<br><a href="http://rob.opendot.cl/index.php/useful-stuff/psp-video-guide/">http://rob.opendot.cl/index.php/useful-stuff/psp-video-guide/</a> and<br>

Thanks for the link. I checked it out, but like I said I want full native res. :) I watch enough video on the PSP to warrant it.<br></div></div><br>Cheers,<br><br>Paul.<br>
