Creating an AVPlayerItem for a video when needed and feeding it to the AVPlayer. Especially since I had to deal with videos of very high resolution. Devices with lower amount of RAM was a problem though since having several videos in memory at the same time consumed too much memory. The third with having two AVPlayers and let them take turns worked great in practice. Further I had a problem with pausing the video exactly between two videos in the composition since the API could not provide frame guarantee for pausing. The first option where I used on big AVComposition with all the videos in it was not good enough since there was no way to jump to a specific time in the composition without having a small scrubbing glitch. So the project is now live in the App Store and it is time to come back to this thread and share my findings and reveal what I ended up doing. Image (2).jpg -> Image (002).jpg) use strict Ĭhomp(my $localdir = `pwd`) # invoke the script in the parent-directory of theĪlso from above answer: rename 's/d+/sprintf("%04d",$&)/e' *.png for i in *.png do mv $i `./zeropad.sh $i` done png files in the current directory such that they are zeropadded. Which will return the result frame001.pngĪll that remains is to use this script to rename all of the. You can then use the zeropad.sh script as follows. Save the above to a file called zeropad.sh and then do the following command to make it executable chmod +x.

Here’s how to do that in bash #!/bin/bash In other words I replace file1.png with file001.png and file20.png with file020.png and so on. Os.rename(os.path.join(path,oldname), os.path.join(path,newname)) zfill(4) + ".png") for x in os.listdir(path) if x.startswith("output_") and x.endswith(".png")] You could compile a list of valid filenames assuming that all files that start with "output_" and end with ".png" are valid files: l =. Os.rename(os.path.join(path, filename), os.path.join(path, new_filename)) New_filename = prefix + "_" + num + ".png" This is useful when the template AVS script expects multiple variables. Using the Import instruction, it is possible to externalize all the variable declarations into its own script. This allows me to simply drag-and-drop several source videos onto the batch. "%vdub%" /i "%pth%Template.vdscript" "%pth%_tmp.avs" A batch script then simply prepends the line with the variable for each video file, similar to this: off
#AVISYNTH SHOULD I REMOVE IT FULL#
I have a script template.avs which expects a variable ( v) containing the full path of the source video. I use this when I have a AVS script where the only parameter which changes is the source input file. I know this is not the answer you're looking for - nevertheless two approaches for generating scripts: Template script Generating scripts on the fly is the only way I was able to get it working. I've never found a way to pass a command line parameter directly to a AVS script.
