quick ffmpeg audio-video encoding usage help
o from last 2-3 days I spent my so much time on file conversion with ffmpeg and mencoder.
After work done, I got some good links to follow for my future help and for all other readers.
- FFMPEG documentation lies here – http://ffmpeg.org/ffmpeg-doc.html ( This will give you the over all idea, if you want to know each and ever thing use this.
- Video/Audio Encoding Cheat Sheet, This is awesome page this will give the quick idea about ffmpeg and converting methods. from here – http://www.rodrigopolo.com/ffmpeg/cheats.html
- The next document is – http://howto-pages.org/ffmpeg/ – this will give the some more detail about ffmpeg with installation help and usage and more examples.
- Obviously you can not miss what wikipedia says about ffmpeg – http://en.wikipedia.org/wiki/FFmpeg
- Some 19 ffmpeg commands you can not miss from here – http://www.catswhocode.com/blog/19-ffmpeg-commands-for-all-needs
- IF you are using libx264 for high quality video then you have to have a look here – http://rob.opendot.cl/index.php/useful-stuff/ffmpeg-x264-encoding-guide/ and here – http://rob.opendot.cl/index.php/2008/09/17/ffmpeg-libx264-presets/
- I used FLVTool2 also for flv manipulation tool for Macromedia Flash Video files (FLV). I used this for meta injection. useful link here- http://osflash.org/flvtool2
The command what I tried for my use is like this
For High Quality and FFMPEG and libx264 vcodec i used this.
/usr/bin/ffmpeg -i /home/ganu/public_html/video/316.mp4 -b 1M -bt 4M -vcodec libx264 -pass 2 -vpre hq -acodec libfaac -ac 2 -ar 44100 -ab 192k -threads 0 -s 552x311 -bufsize 200000000 -f flv -y /home/ganu/public_html/flvideo/316x.flv
Finally I used this this is working fine.
/usr/bin/ffmpeg -i /home/ganu/public_html/video/316.mp4 -r 30000/1001 -b 2M -bt 4M -acodec libfaac -ac 2 -ar 44100 -ab 192k -s 552x311 -f flv -y /home/ganu/public_html/flvideo/316x.flv
/usr/bin/ffmpeg -i /home/ganu/public_html/video/316.mp4 -f image2 -ss 00:00:1 -s 120x90 -vframes 2 -y /home/ganu/public_html/tmp/thumbs/316/%08d.jpg
For metadata injection i used like this.
/usr/bin/flvtool2 -Uv /home/ganu/public_html/flvideo/316x.flv /home/ganu/public_html/flvideo/316.flv
So first say the file 316.mp4 is converted to 316x.flv. And after flvtool2 the meta information is injected and final file will be 316.flv
So this is how, the flv conversion is done.

india startup tips in proto.in
No , No I am not a strtup guy. I don’t have any thing to start now.
Yea but I can work for you. So if you have any thing to work/code/analyse/test/hack then let me know, that I can do that.
Yesterday I was watching the Official proto.in video channel and after so many days I liked the talk given my Mr. Mahesh Murthy. I really got some energy to think more for some idea and work for it. Let see.
Here i am summarizing the points what he mentioned in his talk, that will be helpful for me and other in future.
- If you have a product in your mind don’t even bother just go ahead. Your idea is your idea and if you think is good then just go ahead.
- Price – Price of the product is your weapon.
- Never give lesser price to your product. Analyze the price and give the competitive price of your product. Your price would give the tension to your competitor.
- He gave good example that if you are 20 person company then by lesser price you can never catch a 2000 person company, they will be
always ahead. - Only competitive price will give tension to the opposite party.
- User Interface – UI should be good. No compromise with UI.
- bad, crappy UI shows the cheapness in your product.
- Good UI will give good competition.
- Customers – Getting customers/users for your site.
- Any startup look for first 100 customers. If they are with feel-good-fector then automatically 100 will converted to 100*n times.
- Get your customers/users from confs/events/get-together. At these places you can adv your product free of your cost.
- For paid confs/events, represent your self as speaker so your will get free entry.
- Marketing – He gave one statement, sorry I dont understant that.
- Not necessary that more budget will give more success.
- “Competence is a marketer, is inversely proportional to your marketing budget.” I really don’t understood this.
- “More the budget is less the brain”.
- Be the Master
- Be the master in your field.
- Do some research in your field and you should be thought leader in your field.
- Don’t follow the trends
- You can almost never be successful by following the trend.
- Trend is like end.
Wow, what a nice talk, you can get/see/watch/listen more talk on Official proto.in video channel.
Till then I will collect more talk and summarize this for you all and for me too.
Happy Startup.
Symfony Criteria for table alias with join of same table
Symfony Criteria for table alias and join a quick example.
Yesterday got a good situation, A kind of join with same table and with table alias.
I need to use the first query with symfony criteria.
I got this, hope this will be usefull to you too.
SELECT u1.USR_FNAME AS a, u1.USR_LNAME AS b, u2.USR_FNAME AS c, u2.USR_LNAME AS d, u3.USR_FNAME AS e, u3.USR_LNAME AS f FROM tbl_test LEFT JOIN tbl_users u1 ON ( tbl_test.TEST_USER1_ID = u1.USR_ID ) LEFT JOIN tbl_users u2 ON ( tbl_test.TEST_USER2_ID = u2.USR_ID ) LEFT JOIN tbl_users u3 ON ( tbl_test.TEST_USER3_ID = u3.USR_ID ) ORDER BY tbl_test.TST_ID ASC LIMIT 10
$c = new Criteria();
$c->clearSelectColumns();
$c->addAlias('u1','tbl_users');
$c->addAlias('u2','tbl_users');
$c->addAlias('u3','tbl_users');
$c->addSelectColumn(TblProjectPeer::TST_NAME);
$c->addAsColumn('a','u1.USR_FNAME');
$c->addAsColumn('b','u1.USR_LNAME');
$c->addAsColumn('c','u2.USR_FNAME');
$c->addAsColumn('d','u2.USR_LNAME');
$c->addAsColumn('e','u3.USR_FNAME');
$c->addAsColumn('f','u3.USR_LNAME');
$c->addJoin(TblTestPeer::TEST_USER1_ID,'u1.USR_ID',Criteria::LEFT_JOIN);
$c->addJoin(TblTestPeer::TEST_USER2_ID,'u2.USR_ID',Criteria::LEFT_JOIN);
$c->addJoin(TblTestPeer::TEST_USER3_ID,'u3.USR_ID',Criteria::LEFT_JOIN);
Or take another example
SELECT a.id FROM article a RIGHT JOIN article b ON a.article_id = b.id ORDER BY a.name DESC, b.date DESC
$c=new Criteria();
$c->addAlias('a', 'article');
$c->addAlias('b', 'article');
$c->addSelectColumn('b.id');
$c->addSelectColumn('a.article_id');
$c->addDescendingOrderByColumn('a.name');
$c->addDescendingOrderByColumn('b.date');
$c->addJoin('a.arcticle_id','b.id','RIGHT JOIN');
$rs = ArticlePeer::doSelectRS($c);

obsarvation at borivali station – railfanning
A railfan, railway enthusiast or railway buff is a person interested in an amateur capacity in rail transport.
Though I love planes too but rail fanning is another adventure.
At 2100 hrs I was at borivali station BVI.
- 2104 IST WCAM – 2 Shatabdi Express ahmedabad mumbai. at PF 5
- 2121 IST WCAM #21818 Ahmedabad – Dhanu Road. PF5
- 2130 IST 9005 BCT-OKAH ( Mumbai Central – Okha ) at PF 4
- 2140 IST WCAM #21816 Bandra Jaipur Aravali Expresee 9707 at PF 6
So you know what this WCAM means. This is the indian railway engine code.
WCAM
W – A loco which run on broad guage.
CA – Electric loco ( AC/DC ) which run on both AC/DC
M – Loco used for both passenger and goods trains.
So thats why its WCAM model. So next time if you see any engine which says WCAM then you will also get the same idea.
Now a days I am learning more about rail stuffs. I will update soon as I will learn any thing more on same.
Happy Railfanning.
bole to me mumbai coder – “मी मुंबई coder”
New to mumbai, but language is super cool here.
Even I have observed that I am using some of the phrases for my/our daily use.
यार लग रहा है loop मैं कुछ लोचा है … सुन ना, तेरा हुआ क्या … ज्यादा लोड मत ले, ये code तो automatic चलेगा … यार, क्या deadline दिया है, मेरी तो फट रही है. अरे! क्या ज़क्कास code लिखा है तुने आईला !! क्या बात कर रहा है , सच मैं…. हट साले ! एक दम अतरंगी है …
And many more…
बोले तो, अपुन का एकदम मस्त चल-रेला है. तू बोल न तेरा कैसा चल रहा है…
live joke
This time in my Gtalk I put the message as
“शायद आप कुछ कहना चाहते थे ? शर्माओ मत बोल दो.”
One of my old collage friend came online and told me
friend: अरे ganu भाई, क्यों लोगो के धंधे की vaat लगा रहे हो, you can not use the punch line of others business.
me: why what happend ?
friend : ऐसा लग रहा है , की कोई गुप्त रोगों का clinic खोल लिया है. and you wanted to say “शायद आप कुछ कहना चाहते थे ? शर्माओ मत बोल दो.”.
me : WTF…. I smiled![]()
and then बरबस मुझे अपना status message change करना पड़ा.
