Why does ffmpeg need DNS resolver as its dependencies ?
20 décembre 2019, par KshitijI was installing FFmpeg and libav today using
brew install ffmpeg libavwhen I noticedunboundin the dependencies list.It’s very strange because
unboundis DNS resolver and why ffmpeg would need it.❯ brew install ffmpeg libav

Python FFmpeg : Setting VBR and BT.709
14 décembre 2019, par CryptonautI’m using this Python library to programmatically generate a short video using an image (.png) as input. The video needs to match the specifications of another video created by someone else.
The key differences between my output and the other are the following (these are the media attributes I desire to have) :
- BitRate_Mode : VBR
colour_primaries : BT.709(Solved via the comment made by Rotem - updated my code example to include the solution)
How would I achieve VBR ? It was my understanding ProRes 422 HQ natively used unconstrained VBR yet my output specifies CBR.
Secondly, as can be seen from my code, I’m attempting to conform to BT.709. However, my media information output does not specify this. What am I doing incorrectly ?Here’s my code :
image = ffmpeg.input(input_image, t='00:00:10', framerate='24000/1001', loop='1', probesize='42M')
output = ffmpeg.output(image, output_video,
f='mov',
vcodec='prores_ks',
vprofile='3',
pix_fmt='yuv422p10le',
g='48',
video_track_timescale='24000',
movflags='use_metadata_tags',
timecode='00:00:00:00',
color_primaries='bt709',
color_trc='bt709',
colorspace='bt709',
qcomp='1',
# BT.709 issue solved by adding the bsf option as seen via the line below
bsf='prores_metadata=color_primaries=bt709:color_trc=bt709:colorspace=bt709',
vf='scale=in_range=full:in_color_matrix=bt709:out_range=full:out_color_matrix=bt709')
output.run()Here’s the media information produced by my output :

Empty stream when cutting a video using ffmpeg
17 décembre 2019, par dscvWhen I try cutting a video, it outputs an empty stream (262 byte video with 0s duration). Would appreciate any insight, thanks.
Command used :
ffmpeg -i /path/to/long/video.mp4 -ss 37.69 -t 4.96 -c copy /path/to/short/video.mp4However, when I the following (more inaccurate) command, it outputs a video. This video also has some problems, as the last frame is repeated several times, making the video one second longer (with a frozen image for one second).
ffmpeg -ss 37.69 -i /path/to/long/video.mp4 -t 4.96 -c copy /path/to/short/video.mp4ffmpeg version :
