vcodec

vcodec - Squeeze69

quick and dirty program to test for particular vcodec in an AVI (or any format supported by RIFF library)

program written in GO

Scan a RIFF file for the codec (vids in the strh and the structure in the following strf section), then exit with an error level 1 if the video codec is listed on the command line. The "heavy lift" is made by the image/riff library.

It's partially based on one of the examples in the image/riff section (the read chunk,etc...).

i.e.:

vcodec file.avi DIV3 DX50 ... (case insensitive)

It's quite useful when you want to re-encode with ffmpeg or others a bunch of files only if they use certain codecs
