…more image frames in transcoding multi-image file formats. The parameter is translated in actual frame selection syntax supported by ImageMagick. Use the more portable "escapeshellarg" function in selecting the first image frame in still generation.

For still generation I earlier added selecting the first image frame in multi-image file formats. This is also useful in transcoding, but needs to be more general since the target file format is not restricted to jpeg. So I added a fictive "-source-frame-range" parameter for selecting one or more image frames. This fictive parameter is translated to actual frame selection syntax supported by ImageMagick. For instance:
convert source.tiff -resize 800x600 -source-frame-range 0-2 target.tiffwill be translated to
convert source.tiff[0-2] -resize 800x600 target.tiff(
-source-frame-rangeis not a validconvertoption)
