ffmpeg : Invalid data found when processing input
20 septembre 2018, par Rich_FI have a situation where
ffmpeg
is throwing an error :Invalid data found when processing input
I’ve reviewed other answers here, but my situation is different. I generate in
Ruby
, a text file with a list of input files I want to concatenate together into one large video.I generate in
Ruby
, the command meant forbash
, which is also output for me to manually copy :ffmpeg -y -f concat -safe 0 -i /Volumes/Dragon2/Yums/randoms.txt /Volumes/Dragon2/Yums/final.mp4
Throws an error :
/Volumes/Dragon2/Yums/randoms.txt: Invalid data found when processing input
Here is that file :
file '/Volumes/Dragon2/Yums/0CEDC3CA-4571-4271-9938-A161EC2A887B.mov'
file '/Volumes/Dragon2/Yums/0D25D907-D053-443B-AFC6-9F12B1711BBF.mov'
file '/Volumes/Dragon2/Yums/6A272808-7706-435D-801E-ACE6B42EC749.mov'
file '/Volumes/Dragon2/Yums/6E9BA2F1-C5E7-4C1C-B290-D116105732FA.mov'
file '/Volumes/Dragon2/Yums/0A41C7B7-74CE-484E-B029-3AE57B8BB4EA.mov'When
bash
runs it, it complains about the input file randoms.txt having invalid data. When I copy and paste the very same command inbash
, it works fine. I’m stumped as to how the two are different and whyffmpeg
is not happy when initiated in theshell
.How can I get this to work ? What am I missing ? Cheers
EDIT : Original
ruby
code :`clear`
require 'pathname'
require 'pp'
s = '/Volumes/Dragon2/Yums'
files = []
Dir.foreach(s) do |path|
files << "#{ s }/#{ path }"
end
result = files.sample(files.size) # randomizer
f = File.open("#{ s }/randoms.txt", 'w+')
result.each_with_index do |item, i|
pp "#{ i }: #{ item }" if item.include?('mov')
f << "file '#{ item }'\n" if item.include?('mov')
end
`echo `
File.delete("#{ s }/final.mp4") if File.exists?("#{ s }/final.mp4")
s = "ffmpeg -y -f concat -safe 0 -i #{ s }/randoms.txt #{ s }/final.mp4"
puts s
sleep 3
`#{ s }`I have also tried
system s
as well with the same error. The syntax is generated fine, output fine, operates fine manually. -
ffmpeg UDP stream incomplete using WEBM (VP9)
21 janvier 2018, par DerLarsI’m trying to encode a raw (YUV) video into VP9 and to stream it with ffmpeg via UDP.
Sender command :
ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 352x288 -r 25 -i ReferenceVideo_200Frames.yuv -c:v libvpx-vp9 -lossless 1 -f webm udp ://localhost:1337
Receiver command : (started first)
ffmpeg -i udp ://localhost:1337 -vcodec copy ReferenceVideo_200Frames_Streamed.webm
The testvideo used for this has exactly 200 Frames.
The final output of the sender is :
frame= 200 fps= 14 q=0.0 Lsize= 7918kB time=00:00:07.96 bitrate=8147.3kbits/s speed=0.574x
video:7912kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead : 0.064364%But as soon as the sender finishes, the receiver gets stuck at : frame= 181 fps= 13 q=-1.0 size= 5226kB time=00:00:07.20 bitrate=5945.5kbits/s speed=0.531x
The final streamed video is now incomplete.
So my question is : What am I doing wrong that the stream is incomplete ? Did anyone face this issue too and was able to fix it ?
Many thanks in advance.

FFMPEG XFade Transition
21 juin 2022, par UserErrorLoLI am attempting to use xfade transitions to link multiple video files but I have noticed that the transition does not finish in most cases. If I set the duration to 1 second, it may get 1/4 through the screen before instantly starting the next video. Does this have something to do with my ffmpeg settings like framerate ? My current call is
ffmpeg -i inputs 1-10 -aspect 16:9 -filter complex video_fades -map [final] -c:v libx264 -preset ultrafast -crf 28 out.mp4


The inputs are all 1920x1080 60fps videos and the video fades graph is




[0:v][1:v]xfade=transition=wipeleft:duration=2.000000:offset=32.700[v01] ;
[v01][2:v]xfade=transition=squeezeh:duration=2.000000:offset=125.400[v12] ;

[v89]format=pix_fmts=yuv420p[final]




Has anyone else had this problem and knows how to fix it ?
