Thread: Video codec advantages vs disadvantages

-

what favorite video codec (avi, divix, mpeg, etc), , how make them?

have bunch of vob. files windows dvd rips , make single compressed files pc playback only.
codec should use? can adjust bit rate or resolution preferences? program should use?

thanks.

avi not codec, container format. divx codec, brand of series of products, including divx codec, divx player , divx container. proprietary , run on windows , mac. open source equivalent codec, available linux xvid. mpeg standard audio/video compression, includes container , specifications used several codecs.

examples of video containers: avi, mp4, mkv, mov, mpeg, ogg.

use mkv, avi , mp4. mkv best in opinion, because supports multiple streams , features, including subtitles. formats better others, depending on how going watch. instant, hardware xbox, ps3 , standalone dvd players have limitations on formats , codecs can play.

codecs, use ffmpeg's libavcodec codec family, more mpeg4 (mpeg-4 asp), mjpeg (motion jpeg) , libx264 (mpeg-4 avc/h.264) video , libfaac (aac) , mp3lame (mp3) audio stream.

convert vobs can use mencoder.

examples of mencoder commands using codecs/formats:

code:
mencoder source.vob -o output.avi -oac lavc -lavcopts acodec=libfaac:abitrate=128 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1200
code:
mencoder source.vob -o output.avi -oac lavc -lavcopts acodec=libfaac:abitrate=128 -ovc lavc -lavcopts vcodec=mjpeg:vbitrate=1200
code:
mencoder source.vob -o output.mp4 -oac lavc -lavcopts acodec=libfaac:abitrate=128 -ovc lavc -lavcopts vcodec=libx264:vbitrate=1200
the x264 extremely slow, renders best quality results. don't use it. best speed/quality ratio find mpeg4. mjpeg codec renders better results mpeg4 decent encoding speed, although bigger file sizes.

fore more info mencoder options see this

can transcode/edit/merge several formats mkv files mkvtoolnix-gui.

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...

hi all, i bought arduino (or should genuino) starter kit. first test , failing. i have follow religiously first pages , when trying upload blink sketch, uploading fails avrdude error : avrdude: stk500_recv(): programmer not responding. as suggested in other posts, have tried 1) switch latest hourly build of arduino ide 2) switch previous stable version of arduino ide (1.6.09) 3) change usb cable 1 know working fine 4) make same steps on computer (unfortunatelly, of them macos running on macos 10.11.6, not interesting test) 5) press reset before upload, interesting thing : tx led never flashes the full log attached. idea of why happening ? to save people having download log, it's sync error, resp=0x00 every time: code: [select] avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer not responding and he's running 1.6.11 hourly avrdude 6.0.1. ...
