How to get the output resolution after successful encode ?
11 janvier 2021, par Daniel Birowsky PopeskiI'm using fluent-ffmpeg and I'm already able to get the output resolution in the 'on end' event :


createFfmpegCommand()
 .input(fs.createReadStream(readPath))
 .noAudio()
 .fps(30)
 .format('mp4')
 .videoCodec('libx264')
 .videoFilter([
 {filter: 'scale', options: '1920:1920:force_original_aspect_ratio=decrease'},
 {filter: 'setpts', options: '1.5*PTS'},
 ])
 .outputOption('-crf 30')
 .outputOption('-movflags frag_keyframe')
 .outputOption('-movflags +faststart')
 .output(mp4WriteStream)
 .on('start', () => console.log('processing started'))
 .on('error', err => console.error('err', err))
 .on('end', (_,res) => console.log('processing success',res))
 .run();



However, i'd like it to be machine-readable (json or xml). Instead, it looks like this :

Which doesn't let me be comfortable that my regex to extract the output resolution is always going to work.


Also, I don't wanna make another call/fileread just to get the resolution. Mainly because my files are stored in S3, where
ffprobe
doesn't work.

ffmpeg : Command Execution failed
29 janvier 2019, par PRABHJOT SINGHI am using this plugin plugin link and I am uploading mp4 videos and trying to compress the video on the server using node js FFmpeg module
var vid = new ffmpeg( './' + req.file_name + '.mp4');

res.send({status: 404, message: 'Unable to save video' })
} else {

How to config FFmpeg for xrgb and Aver Media capture card [closed]
12 mai 2023, par Plotter DesalorI'm trying to use FFmpeg through ffplay to display a capture card output as lossless as possible.


My capture card is named "Live Gamer Ultra-Video"


In OBS, the NV12, YV12, P010 and YUY2 lead to blurriness around text and fine pixels edges, but the XRGB one offer clear output. So I've tried to focus on this mode with FFmpeg as the default one lead to same blurriness seen in OBS.


Running "ffmpeg -f dshow -list_options true -i video="Live Gamer Ultra-Video" show me this result
(i've only kept line with wanted resolution)

video=Live Gamer Ultra-Video: Immediate exit requested



"unknown compression type 0xE436EB7D" is a pretty bad start but from https://trac.ffmpeg.org/ticket/6279 I could figured out it was just unproperly parsed RGB24 format


But if I run a very simple "ffplay -f dshow -i video="Live Gamer Ultra-Video" -pixel_format rgb24"
I got this output

How could I use rgb format with this capture card ?


If not possible, any other format leading to proper output would be ok too.
I've tried parameters from this topic Capture full-range/lossless rgb frame from capture card that supports NV12 and YUYV output without any good result sadly.
