Video converted to FLV using FFMPEG gets 0 size
11 novembre 2011, par SudhirI'm trying to convert avi file to flv format using FFMPEG on server, but its giving me problems. On conversion, the file is converted to flv format but no data (0 kb size file). Tried debugging the code but could not. The FFMPEG is installed in CentOS, in path /usr/bin/ffmpeg, and i'm using following command for conversion :
$srcFile = "/home/mydomain/public_html/demo/test/sample.avi" ; $destFile = "/home/mydomain/public_html/demo/test/sample_again.flv" ;
$ffmpegPath = "/usr/bin/ffmpeg" ;
$flvtool2Path = "/usr/local/bin/flvtool2" ;$command = $ffmpegPath . " -y -i " . $srcFile . " -ar 32000 -ab 32000 -f flv -s 320x240 ".
$destFile . " | " . $flvtool2Path . " -U stdin " . $destFile ;exec($command, $output) ;
print_r($output) ;I tried doing :
exec("which ffmpeg") ;
And it gave me the path /usr/bin/ffmpeg, but get following error when i execute the code :
Array ( [0] => ERROR : undefined method `timestamp' for nil:NilClass [1] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flv/stream.rb:285:in `lasttimestamp' [2] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flv/stream.rb:274:in `duration' [3] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flvtool2/base.rb:181:in `add_meta_data_tag' [4] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flvtool2/base.rb:137:in `update' [5] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flvtool2/base.rb:47:in `send' [6] => ERROR : /usr/local/cpffmpeg/lib/ruby/site_ruby/1.8/flvtool2/base.rb:47:in `execute !'

What could be the problem. Is this the problem of Flvtool2, if yes then what is it. Please suggest something

FFMPEG - Watermark video with same quality and filesize
29 mars 2012, par ddlshackI have some videos, and I'd like to watermark them with a transparent PNG. Here's what I've tried :
ffmpeg -i 9.flv -vf "movie=logo.png [watermark];[in][watermark] overlay=10:10 [out]" 9_w.flv
However, bitrate or quality is not preserved. Preferably I'd like ffmpeg to re-encode the file with exactly the same settings as the original file (same codecs, bitrate). If thats not easily possible, I'd like to encode with a specific codec, but preserving 'quality', however that is measured.
