I got an Ipad last week and decided to go ahead and try this feature.</div><div>I have managed to get it working but it is extremely slow. It takes about 6 times longer than the recording it is converting.</div><div><br></div><div>I have installed the airvideo server (via wine not the native linux one) and converting the same file it takes 1/2 the time</div><div>of the recording.</div><div><br></div><div>For example:</div><div>Program<span class="Apple-tab-span" style="white-space:pre"> </span>: Monster Moves AUG 28</div><div>Format<span class="Apple-tab-span" style="white-space:pre"> </span>:HD 720P</div><div>Size in Myth<span class="Apple-tab-span" style="white-space:pre"> </span>:1 hour 5 minutes (4.9GB)</div><div>time to convert in myth export: 7 hours (and then I cancelled)</div><div>size mythexport:<span class="Apple-tab-span" style="white-space:pre"> </span>657 MB when cancelled</div><div>time airvideo<span class="Apple-tab-span" style="white-space:pre"> </span>: 36 Minutes</div><div>size export airvidieo: 537MB</div><div><br></div><div><br></div><div>The machine is a VM running on Citrix Xen Server 5.5 and has been configured with 4 CPUS, 1 GB of ram and 500 GB of HDD space.</div><div>The Underlying CPU is an <span class="Apple-style-span" style="font-family: 'trebuchet MS', Arial, Verdana; border-collapse: collapse; font-size: 14px; line-height: 21px; ">Intel Core 2 Quad Q9400 @ 2.66GHz.</span></div><div><br></div><div>I understand that both mythexport and airvideo use ffmpeg (as far as it is a requirement for both) so I am not sure what the difference could be.</div><div>However I noticed the following:</div><div><br></div><div>1. Myth took about 3 hours to actually start writing the converted file. During that time the two companion files xxx264.xxx. and ffmXXX.XX were being</div><div>populated.</div><div>2. When Mythexport was doing the conversion ffmpeg was running at 100% on only one core. It would jump around cores every 10 minutes or so</div><div>but it never used two cores at the same time. As a result the total CPU usage was always < 25%.</div><div>3. When Airvideo was doing the conversion all 4 cores ran at ~80% for the whole 36 minutes.</div><div><br></div><div><br></div><div><br></div><div><span class="Apple-style-span" style="font-family: 'trebuchet MS', Arial, Verdana; border-collapse: collapse; font-size: 14px; line-height: 21px; "></span>INFO ON THE MYTH SETUP</div><div><br></div><div>Version : Mythbuntu 9.10 which was upgraded to 10.4LT by upgrading Ubuntu, enabling the myth repos and enabling 0.23.1 as the target version</div><div>MythExport: Hacked the script file (can't remember the name) to use libfaac instead of lamemp3 (so that I could sync the files with Itunes)</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>The conversion job is configured as follows</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>- Resolution : 704*576</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-Aspect: 16:9</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-Audio rate: 192kb</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-Video rate: 1800kb</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-Codec: h264</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>- Remove commercials= yes</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>-Audio channels: 2</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>The job is not setup to run automatically.

I did a test run with the same setting except the video rate was at 600Kb. It was a standard def file and only 29 minutes long. The output looked good on an iphone but too pixelated on the ipad. I converted the same file using handbrake (on a different computer so I wasn't comparing conversion times) with the "universal" preset which looked great on the ipad. I checked the file's details and the only difference with the mythexport one was the video rate so I changed that in mythexport.</div><div><br></div><div><br></div><div>I rather use mythexport for the file/job management capabilities but at those speeds It is useless for converting files on a regular basis.</div><div><br></div><div>Any suggestions will be greately appreciated.</div><div><br></div><div><br></div><div><br></div><div><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div><font class="Apple-style-span" face="Arial" size="3"><span class="Apple-style-span" style="font-size: 12px; ">Diego</span></font></div></span></span></span></span></span></div><br></div></body></html>
