<content:encoded><![CDATA[<p>Muchos diréis que el formato VCD es bastante pobre, de mala calidad. Es cierto. Pero algunos, como el aquí presente, han <em>petado</em> su disco duro multimedia y no poseen un reproductor dvd con soporte para DiVX. La solución más económica mientras arreglo el disco duro es convertir a VCD.</p>
[caption id="attachment_1349" align="aligncenter" width="273" caption="Store&#38;Play 3500 500 GB"]<a href="http://arbolcharyou.wordpress.com/files/2008/09/hdmultimedia.jpg"><img class="size-full wp-image-1349" src="http://arbolcharyou.wordpress.com/files/2008/09/hdmultimedia.jpg" alt="" width="273" height="273" /></a>[/caption]
<p>Ahora bien, hasta el momento usaba la aplicación DeVeDe pero no la he encontrado aún para Debian. Tiempo al tiempo. Es por esto que he decidido usar <strong>ffmpeg</strong> y resulta bastante simple una conversión estándar.</p>
<p><strong>Instalamos:</strong></p>
<blockquote><p><em>apt-get install ffmpeg</em></p></blockquote>
<p><strong>Convertimos:</strong></p>
<blockquote><p><em>ffmpeg -i input.avi -target pal-vcd output.mpg</em></p></blockquote>
<p>Rápido, sencillo y efectivo. Por supuesto, siempre se pueden ajustar más las opciones para mejorar la calidad.</p>

<content:encoded><![CDATA[<p>Когда снимался небольшой <a href="http://znoxx.wordpress.com/2008/09/01/cc08-video-bootleg/">ролик про NeoGS и Пентагон</a> - при его длительности около 3 минут - размер просто зашкаливал - около 125 мегабайт. Конечно, ни о какой публикации в реальном времени речи нет вообще. Ситуацию можно исправить. Зарубежный коллега приводит вот такой способ предварительной конвертации видео с камеры:<br />
<code><br />
$ ffmpeg -i DSCF0370.AVI -b 800 -s 320x240 -vcodec mpeg4 -r 30000/1001 out.avi<br />
</code><br />
Полный текст статьи <a href="http://www.shahidhussain.com/blog/?p=32">вот здесь</a>.</p>
<p>Суть в том, что после конвертации файл становится размером 320х240  (это нормально для YouTube), плюс к этому его размер уменьшается раз в 5 (в моем случае 125Мб -&#62; 22Мб)</p>
<p>Технические вопросы. Есть такая неприятность - свежеустановленный из пакетов ffmpeg у меня отказался понимать mpeg4 в качестве выходного формата. В результате я запускал ffmpeg от Win32 через Wine. Правда в качестве bitrate нужно казывать не 800, а 800000. Чтобы не мучиться со звуком, я использовал параметр <code>-acodec copy</code>.</p>

<content:encoded><![CDATA[<p>I found this command that successfully strips the audio into a wav file:</p>
<pre class="code">ffmpeg -i Blessed_Be_Your_Name.flv -vn -acodec pcm_s16le \
   -ar 44100 -ac 2 Blessed_Be_Your_Name.wav</pre>
<p>Here is the same command that includes the video that will play in Window's Media Player:</p>
<pre class="code">ffmpeg -i Blessed_Be_Your_Name.flv <code>-vcodec msmpeg4v2</code> -acodec pcm_s16le \
   -ar 44100 -ac 2 Blessed_Be_Your_Name.avi</pre>
<p>I was able to use this command to convert an flv file from a downloaded Google Tech talk to an mp4 file that I could play with mplayer in Linux:</p>
<pre class="code">ffmpeg -i Using_bluemail_to_renew_the_design_and_study_of_enterprise_email.flv \
    -vcodec xvid -acodec pcm_s16le -ar 44100 -ac 2 \
    Using_bluemail_to_renew_the_design_and_study_of_enterprise_email.mp4</pre>

<content:encoded><![CDATA[<p>We have been using Joyent accelerators to host Alpha and Beta versions of some of our products. One of the products that we are building needed <strong>ffmpeg</strong> to convert videos to flv format for streaming. Joyent accelerators use OpenSolaris 5.11. I thought I would just get ffmpeg and install it from source. "make" went along fine for sometime but bombed with the following error:</p>
<p><code>In file included from /usr/include/sys/int_types.h:55,<br />
                 from /usr/include/sys/stdint.h:38,<br />
                 from /usr/include/stdint.h:38,<br />
                 from ./libavcodec/bitstream.h:29,<br />
                 from libavformat/rtpdec.c:25:<br />
/usr/include/sys/feature_tests.h:353:2:<br />
<strong>#error "Compiler or options invalid for pre-UNIX 03 X/Open applications and pre-2001 POSIX applications"</strong></code></p>
<p>So I opened up "configure" and saw the following c99 directives:<br />
<code>check_cflags -std=c99</code> and<br />
<code>add_cflags -D_ISOC99_SOURCE -D_POSIX_C_SOURCE=200112</code> </p>
<p>I look inside the file rtpdec.c inside the directory libavformat and I find this:<br />
<code>#define _XOPEN_SOURCE <strong>500</strong></code><br />
This clearly conflicts with the "-std=c99" settings.<br />
So I change it to<br />
<code>#define _XOPEN_SOURCE <strong>600</strong></code><br />
Two other files utils.c inside libavcodec directory and ffmpeg.c had the same problem. I applied the same fix there.<br />
It compiled fine thereafter and that saved my day.</p>

<content:encoded><![CDATA[<p><a title="official website" href="http://recordmydesktop.sourceforge.net/about.php" target="_blank"><strong>Recordmydesktop</strong></a>, kao sto mu samo ime kaze, pravi video zapis onoga sto se desava na dekstopu. Za razliku od drugih slicnih aplikacija prednost recormydesktop-a je u tome sto obradu snimljenog materijala vrsi <em>nakon</em> zaustavljanja snimanja tako da funcionalnost desktopa nije usporena transkodovanjem koje se desava u pozadini (kao kod xvidcap).   Ovaj nacin snimanja je zahvalan za one koji , kao i ja, imaju kompjutere sa slabijim ili starijim procesorom(PIII).</p>
<p>Archlinux ima ovu aplikaciju u AUR repositorijumu pa je potrebno napraviti pakete za instalaciju.  Trenutna dostupna verzija je 0.3.7.3-1. Sam RMD je command line aplikacija pa je potrebno instalirati neki frontend. Ponudjen frontendovi su <em>gtk-recordmydesktop</em>, <em>qt-recordmydesktop</em> i <em>krecordmydesktop</em>. Ja sam izabrao gtk verziju posto mi je ionako defolt windows manager gnome.  Svi dodatni paketi- zavisnosti se nalaze u oficijalnom repozitorijumu i bice dostupni pacmanu prilikom instalacije.</p>
<p>RMD nema tarball paket za skidanje vec je portrebno pratiti <a title="cvs link" href="http://repos.archlinux.org/viewvc.cgi/community/multimedia/recordmydesktop/PKGBUILD?view=log&#38;root=community&#38;pathrev=CURRENT" target="_blank"><strong>cvs</strong></a> link da bi se daunlodovao najnoviji <strong>PKGBUILD</strong> fajl.  Naravno, PKGBUILD fajl je potrebno premestiti u prazan build direktorijum, otvoriti terminal i kao user kucati</p>
<p><strong>makepkg -s</strong></p>
<p>Ako sve prodje kako treba ovo ce napraviti arch paket koji se zatim instalira kao root kucajuci</p>
<p><strong>sudo pacman -U ime_paketa.pkg.tar.gz</strong></p>
<p>Obratiti paznju na <em>.<strong>pkg</strong></em> u imenu paketa posto je moguce da se u build direktorijumu nalazi jos neki tar.gz paket. Nama je potreban ovaj sa .pkg.</p>
<p>Ponoviti isti proces i za instaliranje gtk-recordmydesktop.</p>
<p>Kada je i to uspesno zavrseno u aplication meniju , pod video, bi trebala da sa pojavi ikona za gtk-record.</p>
<p>Korisnicki interfejs je vrlo jednostavan. Jedno dugme za record, jedno za biranje dela ekrana koji zelite da snimite, dva slajdera za audio i video kvalitet. Ispod slajdera se nalazi dugme za advanced opcije od kojih je meni jedino bila zanimljiva ona o broju fps. Fps oznacava broj slicica  koje program snimi u sekundi. Kod mene je kao defolt stajalo 15 sto ne daje realisticnu sliku vec ima "skakanja". Da bi snimljeni video bio "tecan" i realistican potrebno je povecati broj fps na negde izmedju <em>24 - 30</em>. Ja sam koristio 30 sa iskljucenim snimanjem zvuka i maksimalnim kvalitetom slike. Povecanje fps i kvaliteta slike znaci veci fajl i vece opterecenje procesora. Na 30fps ja nisam imao nikakvih problema i nisam primetio da rad na kompjuteru prilikom snimanja postaje usporen.  Fajl koji sam snimio je bio velicine oko 10mb u trajanju od 4-5 minuta.</p>
<p>Pritiskom na dugme record pocinje snimanje i gtk interfejs nestaje sa ekrana. U gornjem panelu, skroz desno se pojavljuje crno dugme sa kvadraticem koje sluzi za prekidanje snimanja. Prekidanjem snimanja ce se otvoriti prozor sa progres barom koji ce pratiti transkodovanje snimljenog u video fajl. Kada se transkodovanje zavrsi u home direktorijumu ce se naci fajl pod imenom <strong>out.ogv</strong> ili nesto slicno tome. </p>
<p>Da, RMD koristi <em>ogg theora</em> video. Kvalitet dobijenog videa je odlican i ne primecuje se da je rec o videu.  Na zalost, ukoliko zelite da publikujete video na youtube moracete da ga konverujete u neki drugi format. To i nije naraocito tesko i postoji vise nacina.  Ja sam koristio <em>ffmpeg</em> i <em>mencoder</em> sa promenljivim rezultatom. Ffmpeg moze da konvertuje i u flash sto mencoder ne moze.  Ne da ja znam.</p>
<p>Za konvertovanje u .avi sa ffmpeg</p>
<p><strong>ffmpeg -i out.ogv out.avi</strong></p>
<p>za flash</p>
<p><strong>ffmpeg -i out.ogv -b 384000 -s 640x480 -pass 1 -passlogfile log-file out.flv</strong></p>
<p>(ovo daje fajl rezolucije 640x480. Ukoliko je snimljeni ulazni video vece rezolucije promeniti vrednost)</p>
<p>za mencoder u .avi</p>
<p><strong>mencoder out.ogv -o out.avi -ovc lavc -oac lavc</strong></p>
<p>Mencoder je mnogo brze zavrsio posao konvertovanja  i nisam primetio neku veliku razliku izmedju tog .avi fajla i onoga dobijenog ffmpeg-om.  Flash fajl je izgubio malo na ostrini. Youtube prihvata .avi fajlove i kada ga konvertuje u flash dobice se video koji je nekvalitetniji od ulaznog fajla. Rezultat se moze videti <a title="youtube" href="http://www.youtube.com/user/liticovjesac" target="_blank">ovde</a>. </p>
<p>Dakle , recordmydesktop je jednostavan i stabilan program koji zauzima malo resursa i daje kvalitetan video fajl sa kojim se kasnije moze raditi.</p>
