  • FFMPEG reports invalid video resolution, video headers container seem to be different from actual frames !

    20 décembre 2011, par Emiliano

    Quick 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 or WMP, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of 600x480 ....

    I took the time of actually capturing a frame and croping it with photoshop and its 656 and not 600 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 :P

    Is there a way to change the container information with ffmpeg so applications that actually do use the container information don't render video incorrectly ?

  • Using FFMPEG for online video hosting

    20 décembre 2011, par Kyle Monti

    I've been looking around for using FFMPEG and PHP. I've noticed you can use FFMPEG with HTML5. I've read the documentation of the FFMPEG's website and it's far beyond my knowledge. I have an open source document of a 'premade' .php file that stores the information to the database and tells it to execute to the ffmpeg function. However, they use mp4box and FLVtool2.

    The array's of video size, frame rates, etc. are quite easy to understand. When designing this from scratch I really have not idea where to start.

    I've defined the variables that will be recorded once the file is uploaded, thereafter, checking to see if the file exists and recording it the database.

    The real question is using mp4box and flvtool2 to convert all videos right to .flv so you can use flowplayer or jwplayer then telling to convert.

    EDIT : Sorry to edit, I've seen many posts about the same question but they all relate to old versions of the software, will the php carry over to newer versions (probably could find out on their website if they had a more in depth HOWTO for website streaming)
