Extracting relevant information from a long string of ffmpeg data

Question

Hello there,

I'm aware later versions of ffmpeg seem to present this information in a more accessible form, but my application is running on an old version for many reasons right now.

Is it possible to extract

• Format: flv (located after Input #0, )
• Duration: 00:05:23.20 (located after Duration: )
• Bitrate: N/A (located after bitrate: )
• Video: h264, yuv420p, 640x360 [PAR 1:1 DAR 16:9] (located after Video: )
• Audio: aac, 44100 Hz, mono, s16 (after Audio: )

In the knowledge that these figures/strings might change. It seems like a mammoth task in string searches to me, one I've often struggled with and eventually contemplated suicide. Is there a 'quick way'? or any widely applicable logic to getting this stuff.

Thanks in advance for any help.

Use regular expressions and try to match your target strings... see preg_match_all

second way of achieving this is to use PHP's explode().
