Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

Create a "metadata.json" file while saving [MMPEG]
21 mai 2022, par Emre7I am using youtube-dl. I want to create the metadata data of a file while saving, but the JSON file returns empty.


I can get data with —write-info-json but need detailed metadata, like this.


Sample command :


ffprobe -loglevel 0 -print_format json -show_format -show_streams /var/../test.mp4.part > /var/../metadata.json

What could be the reason for this and is there a different way ?

FFmpeg : "filter_complex" results in worse quality than "vf"
16 novembre 2016, par DasmowenatorI’m trying to use FFmpeg to do some complex video transcoding (such as concatenating multiple files). To do this, I’ve been trying to use the filter_complex, but I’ve noticed a slight drop in quality from what I saw earlier using the normal video filter.
To double-check, I boiled down my command to a simple transcode — one using filter_complex and one just using the vf — and I’ve confirmed that the output of the complex filter is noticeably blurry compared to the output of the normal video filter. I can’t find any FFmpeg documentation explaining this... does anyone know why this is happening and how I can get filter_complex to output the same quality video as vf ?
Command using the normal video filter (vf) :
ffmpeg -i input.ts -map_chapters -1 -f mpegts -an -sn -map 0:0 -vf "[in]yadif=deint=interlaced[out]" -vcodec libx264 -profile:v baseline -level 2 -b:v 800k output.tsFFmpeg Output :
