php - ffmpeg 1.0.7 takes minute to create a thumbnail on "broken" video file but other files are seconds to create thumbnail -


i've been using ffmpeg 1.0.7 on 450gb (cca 400 files) creating thumbnails , grabbing video-file information. tooks me 1-2 seconds create 10 thumbnails ~8gb file. i've got 'broken' video file (672 mb) creates me 1 thumbnail on minute, 10 thumbnails on 10 minutes -> server burns:

 pid user      pr  ni  virt  res  shr s  %cpu %mem    time+  command  9769 www-data  20   0  395m  28m 7212 r 157.0  0.4   0:04.99 ffmpeg

i opened file in windows media player , getting blank screen while -> video file weird, opened in vlc , wrote me: because avi file index broken or missing, seeking not work correctly. vlc won't repair file can temporary fix problem building index in memory. i've clicked 'play is' , plays video file correctly, webserver burns because of ffmpeg , php waits return exec(); command. thumbnails created fine after 10 minutes, how can fix problem or prevent executing ffmpeg creating thumbnails on these broken 'video' files?

this php:

$cmd = "ffmpeg -i error.avi 2>&1"; $info = `$cmd`; echo '<pre>'; print_r($info); echo '</pre>';

this output getting (very quickly)

so looks creating thumbnails having problems:

exec("ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");

where problem? suggestions!

btw. posting on because i'm not sure belongs more here - think done somehow php i'm not sure.

edit: have added timeout, "fixes" problem, latest version of ffmpeg 2. stucks on creating thumbnail broken video files.

exec("timeout 5s ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
