      @scorpio588 %CD% in Windows (cmd.exe) is the current folder, you cannot convert a folder, you need to have an input file and a - different - output file as arguments

        Oh, ok. I mistook "<input_file>" above as the directory. In that case, would I have to run this command for each video then? If possible, I'd like to be able to convert all the videos in a directory.

          @scorpio588 Something like (borrowed from https://superuser.com/questions/808302/use-ffmpeg-to-batch-process-m4a-to-m4a):

          forfiles /P "<My_Videos_folder>" /C "cmd /c ffmpeg -i @file <lots of arguments here> @fname-converted.@ext"

            @mitu said in sselph scraper "-convert_videos" not working on Windows 10:

            @scorpio588 Looking at the sselph's scraper source, the command for encoding the videos is

            ffmpeg -i <input_file> -c:v libx264 -preset fast -crf 23 -vfscale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa ac -b:a 80k <outputFile>
            

            You could run it from the command line and see it works. If it fails, then you'll know why ffmpeg refuses to convert the video.

            Where did you find that command in the source code? I got some flags in my last test (still not working but getting closer I think) saying "Unknown encoder 'ac' ".

              I tried running:

              forfiles /P ".\images" /C "cmd /c ffmpeg -i @file -c:v libx264 -preset fast -crf 23 -vf scale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa ac -b:a 80k .\images\converted\\@file.mp4"
              

              and the output for each file looked something like this:

              Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (.\images\converted\Sonic Advance-image.jpg.mp4) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
              .\images\converted\Sonic Advance-image.jpg.mp4: No such file or directory
              

              I realize that I'm doing something wrong with the file name, but before I fix that, is there a way to run this so it only tries to convert .mp4 files? The directory I'm using contains .mp4 and .jpg files. I tried a command:

              for %a in ("*.mp4") do ffmpeg -i "%a" -c:v libx264 -preset fast -crf 23 -vf scale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa ac -b:a 80k "converted\%a.mp4"
              

              and that seemingly did nothing.

                You can use the /m *.mp4 argument to forfiles to filter through the files and only get the .mp4 files.

                    The "80k" error was due to a missing parameter, which was "aac". After figuring that out, I tried this:

                    for %a in ("*.mp4") do ffmpeg -i "%a" -c:v libx264 -preset fast -crf 23 -vf scale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa aac -b:a 80k "converted\%a.mp4"
                    

                    and got:

                      I just realized that I have to use "converted.%~na.mp4" instead of "converted.%a.mp4" to avoid .mp4.mp4 files. So the command looks like this:

                      for %a in ("*.mp4") do ffmpeg -i "%a" -c:v libx264 -preset fast -crf 23 -vf scale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa aac -b:a 80k "converted\%~na.mp4"
                      

                      and I get this:

                        Ok! I got it to work (mostly)! I used the command:

                        for %a in ("*.mp4") do ffmpeg -i "%a" -c:v libx264 -preset fast -crf 23 -vf scale=320:240: -c:aa aac -b:a 80k -r 30 "converted\%~na.mp4"
                        

                        to convert all the .mp4 files in the images folder and store them in images\converted. I'll just have to copy-replace the converted images into the images directory when the conversions are done! There is a chance that some videos will look funny because I'm not preserving the aspect ratio, but they look OK so far to me. The converted videos are all 320x240@30fps!

                        Thank you for your help @mitu!

                          Sorry, there's a typo in the last comment. Use this command instead:

                          for %a in ("*.mp4") do ffmpeg -i "%a" -c:v libx264 -preset fast -crf 23 -vf scale=320:240 -c:aa aac -b:a 80k -r 30 "converted\%~na.mp4"
