My FFMPEG throws me unexpected errors while writing a Thumbnail to the songs
4 mars 2019, par Harmonised7I am using Node to execute my ffmpeg. I use this wrapper :
https://www.npmjs.com/package/ffmpeg
Everything was fine when I was using smaller versions of the thumbnails provided by Youtube, but when I attempted the HD ones, it suddenly started giving me an error. I’ve tried -pix_fmt yuv422p and Many other pixel formats, but nothing helped. Though ONE out of 100+ songs did tag successfully.
here is my code :
downloadTags(tags.thumbnail, `./thumbnails/${tags.title}.jpg`).then(thumbnail =>
{
video.addCommand('-i', `"${thumbnail}"`);
video.addCommand('-map', '0');
video.addCommand('-map', '1');
video.addCommand('-c', 'copy');
video.addCommand('-c:v:1', 'png');
video.addCommand('-disposition:v:0', 'attached_pic');
if(tags.title)
video.addCommand('-metadata', `title="${tags.title}"`);
if(tags.artist)
video.addCommand('-metadata', `artist="${tags.artist}"`);
if(tags.id)
video.addCommand('-metadata', `comment="https://www.youtube.com/watch?v=${tags.id}"`);
video.addCommand('-pix_fmt', `yuv422p`);
var output = 'downloaded'
if (outFolder)
{
output = outFolder;
if(!fs.existsSync(output)) fs.mkdirSync(output);
}
video.save(`"./${output}/${tags.title}.${tags.format}"`, function (error, file)
{
if (error)
{
resolve(error);
return
}
try
{
fs.unlinkSync(song);
}
catch(err)
{
console.log(err.code);
}
resolve();
});
});
}and here is my error :

ffmpeg autodetect and cut black bars on video [closed]
30 octobre 2024, par some_vasyaFILE_SRC="$HOME/some.mp4"
CROP=$(ffmpeg -ss 00:00:15 -i "${FILE_SRC}" -t 00:00:30 -vsync vfr -vf fps=1/2,cropdetect -f null - 2>&1 | awk '/crop/ { print $NF }' | tr ' ' '\n' | sort | uniq -c | sort -n | tail -1 | awk '{ print $NF }')

# before converting, need to check
fplay -vf "${CROP}" # <-- the black stripes remain




Question : how to remove black bars in video correctly so that you can watch video on TV without black bars, taking into account the definition of bars ? I am interested in a solution using ffmpeg, and not other means


I tried to find a solution to work in automatic mode, but I didn't find it


I="$@"
X=${I##*.}
O=${I%.*}_zoomed.${X}
f=$(which ffmpeg 2>/dev/null)
echo ${I}
C=$($f -i "$I" -t 1 -vf cropdetect -f null - 2>&1|awk '/crop/{print $NF}'|tail -n1)
echo "${C}"
echo $f -i "$I" -vf "$C" "$O"; $f -i "$I" -vf "$C" "$O"

Embed a Youtube with a MP4 File as poster
29 août 2021, par adamplI want to embed a youtube video with a 10 second silent looping MP4 file as the poster.


Currently, I am using the Wordpress video shortcode with my MP4 as the poster source, it works on some browsers but not all. Can anyone help ? I would prefer to find a pure HTML solution separate to the wordpress shortcode as I will need to get this to work on other CMSs.


[video src="https://www.youtube.com/watch?v=[videoID]" poster=<video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">
 <source src="/wp-content-directory/intro.mp4" type="video/mp4">
</source></video>]



What i have found is to get a looping MP4 work on all browsers, I have to use this tag with the autoplay loop muted and playsinline


<video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">
<source src="/directory/intro.mp4" type="video/mp4">
</source></video>
