      @mitu Yes, the ffmpeg.exe is in my $path. I was getting "ffpmeg not in $PATH" errors before I added it. I'm not familiar enough with ffmpeg yet, do you know how I could convert all videos in a directory to 320x240@30fps with ffmpeg?

        @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.

          @mitu I'll give that a try! I couldn't find that in the source before. Thanks!

            Ok, I just tried running:

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

            and the cmd prompt gave me:

            Error splitting the argument list: Option not found

            So it's not liking the "vfscale=w=320:h=240:force_original_aspect_ratio=decrease" argument. I'm guessing that ffmpeg was updated but the scraper hasn't changed to reflect that, or the scraper just wasn't tested for this on windows.

              Ok, I had to split "vfscale=w=320:h=240:force_original_aspect_ratio=decrease" into "vf scale=w=320:h=240:force_original_aspect_ratio=decrease".

                Now when I run:

                ffmpeg -i %CD% -c:v libx264 -preset fast -crf 23 -vf scale=w=320:h=240:force_original_aspect_ratio=decrease -c:aa ac -b:a 80k %CD%

                I get a "G:\retropie-mount\roms\gba: Permission denied" error.

                  @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"

                        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:

                          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:

                                  G:\retropie-mount\roms\gba\images>ffmpeg -i "Zelda - the Minish Cap-video.mp4" -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\Zelda - the Minish Cap-video.mp4"

                                    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"
