Does ffmpeg play the entire video file to extract image
21 mars 2012, par user735647I have a multimedia application which involves lot of videos. I use FFMPEG to generate the thumbnails from the video at a particular time duration. Now the problem is my console application which is used to extract the images from the video is consuming lot of memory when its being run.
The doubt I have now is whether FFMPEG does play the entire video file when extracting the thumbnail image.Is it possible ?
Following is the parameter being passed to FFMPEG,
-i [input video file] -an -r 0.05 -y -ss 00:00:18 -vframes 1 [output thumbnail file path]
I tried googling but with no success. Please provide your valuable thoughts.
Thanks.

FFMPEG reports invalid video resolution, video headers container seem to be different from actual frames !
20 décembre 2011, par EmilianoQuick question, i have a movie, which was cut and rendered with Sony Vegas from its original format to a .wmv file. Here comes the tricky part, movie when played, either with
VLC
orWMP
, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of600x480
....I took the time of actually capturing a frame and croping it with photoshop and its
656
and not600
like ffmpeg its reporting, why would this could be happening ? How could i fix the headers resolution ? Would that have any impact on video re-rendering ? As i said, VLC and WMP seems not to care about the incorrect headers and are playing it right, BUT, jwplayer seems to be using the header information, which i don't blame him, its correct to do that, but why the video headers could be wrong ?ffmpeg -i trailer.wmv
Input #0, asf, from 'trailer.wmv' : Duration : 00:01:04.93, start : 3.000000, bitrate : 2144 kb/s Stream #0.0 : Audio : wmav2, 44100 Hz, mono, 32 kb/s Stream #0.1 : Video : wmv3, yuv420p, 600x480 [PAR 59:54 DAR 295:216], 2065 kb/ s, 25.00 tb(r)
And yeah, the
PAR/DAR
parameters are also wrong, but honestly, i don't understand that technical shit, usually watch video and make sure it look good, any feedback would be appreciated :PIs there a way to change the container information with ffmpeg so applications that actually do use the container information don't render video incorrectly ?
