how to build ffmpeg with burn text on hls output while maintaining the aspect ratio
26 février 2016, par AameerMy objective is to burn a text(watermark) at a particular time range on the outputed hls video, I also have to change just the height and maintain the aspect ratio which I am able to do but the burning in text part is not working. First the ffmpeg I used is for 14.04 ubuntu, details are here. I don’t think this build supports subtitle (docs) filter which I could have used for my purpose as described here. when i enter ffmpeg into the terminal this is the output

How to change size of watermark image and set Size and Aspect Ratio of Video using fluent-ffmpeg ?
12 avril 2021, par KirasirisDoes anyone knows how to change the size of the watermark image ? ; secondly I tried to use
complexFilter()with thesize()andaspect()methods but it throws an error of complex-filter can not be used with complexFiltergraph in the same input stream ?

This is my code :


await ffmpeg('tmp/' + file.name)
 .input(waterMarkImage)
 .videoFilter([
 'overlay=10:10',
 'scale=1280:720',
 'aspect=16:9',
 'crop=1280:554:0:90',
 ])
 .output(key)
 .on('progress', function (progress) {
 console.log('Processing: ' + progress.percent + '% done')
 })
 .on('end', function (stdout, stderr) {
 console.log('Finished')
 fs.unlink(dir + file.name, function (err) {
 if (err) throw err
 console.log('File deleted')
 })
 })
 .on('error', function (err) {
 console.log('an error happened: ' + err.message)
 fs.unlink(dir + file.name, function (err) {
 if (err) throw err
 console.log('File deleted')
 })
 })
 .save(dir + key)


Thanks.

ffmpeg 360 Video Conversion - EAC (Youtube) to Equirectangular
18 juillet 2022, par chanteyI have this top-bottom 360 Video, where the bottom is rotated 90 degrees clockwise, and I am looking for the ffmpeg command to produce a singular equirectangular output. I've been experimenting with various ffmpeg 360 filters, but am really just guessing at this point.
