FFMPEG - Palettegen for animations is not working
18 juillet 2018, par deanhodgesI have a script taken from the correct answer at https://superuser.com/questions/1002562/convert-multiple-images-to-a-gif-with-cross-dissolve, but I am getting no results.
Even copying the code word for word does not work for me.
However, if I run
$ffmpeg = shell_exec("ffmpeg -i images/image001.jpg -vf palettegen palette_test.png");
on a single image, it works fine. But because I need it for an animation, I need to create a pallete for all images.Unless of course, on each image in the GIF sequence I can load a new palette ?
$q = "ffmpeg -f image2 -framerate 0.5 -i ../view/client/files/".$dir."/%*.jpg -i palettePro.png -lavfi paletteuse -y .." . $save_path . '/' . $filename . " -report";

Ffmpeg it's not setting the correct variable names and hence throwing Unable to choose format
9 novembre 2024, par Miguel ArriecheI'm trying to automate the subtitle addition to a folder with some videos so I wrote the following script :


forfiles /p "C:\Users\titos\Resilio_Sync\4K_Video_Downloader\videoprocess" /m *.mp4 /C "cmd /c set filename=@fname & ffmpeg -i @file -vf subtitles="C:\Users\titos\Resilio_Sync\4K_Video_Downloader\videoprocess\@fname.srt" -f mp4 "C:\Users\titos\Resilio_Sync\4K_Video_Downloader\donesubs\@fname_srt.mp4""



However, the script is throwing me the following error for each video :


[AVFormatContext @ 0000020c20220680] Unable to choose an output format for 'Der'; use a standard extension for the filename or specify the format manually.
[out#0 @ 0000020c20220580] Error initializing the muxer for Der: Invalid argument
Error opening output file Der.
Error opening output files: Invalid argument



In this case, "Der" is the second word of the video's title (And it does the same with each video where it throws the error with the second word). So I think it might be due to the videos containing spaces and ffmpeg not parsing it correctly ? But why is the second word that it gets and not the first one in that case ? And more importantly, what could I do to fix this issue ?


I've honestly found some other threads that discuss similar issues, but quite frankly I'm still too newbie to understand any of the answers in order to adapt it to my script lol. I appreciate your help, thanks a lot in advance :)
