Resolution attribute for video links?

[Scintilla]

It occurred to me today, why not let creators specify a resolution for each of their video links (optional)?

It seems to me that that's the only major video attribute that isn't listed so far... and I wouldn't be surprised if it was often a factor in people deciding which version of a video to get if multiple versions are offered (people with older computers wanting something they won't choke on, quality Nazis wanting highest clarity, etc.), and I wouldn't think it would be that hard to implement (not that I know anything about PHP).
It could even work for Local links if the file uploaded was an MPEG (like the other attributes do now)...

The information is worked out automatically if it's an mpeg but Phade didnt include something that read avi headers, so it only happens for mpegs.

Yeah, I saw that the resolution's part of the file info that comes up on local MPEG downloads (at the actual download screen), so that's why I mentioned that part of it.

Assuming the transcode toolset is installed on nago (or whereever this file can be accessed to most conveniently generate and store this data), it isn't hard. Here's what you get on standard output from tcprobe when you put it on an AVI file:

Code: Select all

bash-2.05b$ tcprobe -i /mnt/usbdrive/amv/AqStud\(Scintilla\)-EvaBebop.avi 
[tcprobe] RIFF data, AVI video
[avilib] V: 23.976 fps, codec=DX50, frames=2502, width=512, height=384
[avilib] A: 44100 Hz, format=0x55, bits=0, channels=2, bitrate=192 kbps,
[avilib]    2491 chunks, 2503528 bytes, CBR
[tcprobe] summary for /mnt/usbdrive/amv/AqStud(Scintilla)-EvaBebop.avi, (*) = not default, 0 = not detected
import frame size: -g 512x384 [720x576] (*)
       frame rate: -f 23.976 [25.000] frc=1 (*)
      audio track: -a 0 [0] -e 44100,0,2 [48000,16,2] -n 0x55 [0x2000] (*)
                   bitrate=192 kbps
           length: 2502 frames, frame_time=41 msec, duration=0:01:44.354

Resolution, framerate, file length, and a lot more. Extraction is then a matter of string processing, which is easy to do in PHP.

I'm not sure what tool is currently being used to extract data about MPEGs. My intuition says mpeg3dump (from libmpeg3) but I could be wrong...

Should the execution of an external program not be desired (for security reasons; it's a valid justification), it's possible to just interface to avilib (see avilib documentation) by writing a small PHP extension.

I am, I just haven't done anything (yet) :P It's just that there's a lot of other stuff that I need to do before any .org work is done.

Hey, the default resolution and framerate are PAL

I was originally referring more to direct and indirect links, and having the user input the resolution him/herself, but this talk is good too
(I'm never quite comfortable when I can't see the file info on a local link...)
