FFMPEG Debug "Invalid data found when processing input"
29 septembre 2020, par dgcippHow can I debug this error ? I am trying to display a vp8-encoded video stream (TCP) from Android (x86) to my PC but I got this message from ffplay : "tcp ://10.8.0.3:49152 ? listen : Invalid data found when processing input"


With h264 it works and the same code in an android device works with vp8 too.


Command in the server :


ffplay -i tcp://10.8.0.3:49152?listen



I have tried adding verbosity or log-level debug, but it shows the same. How can I get a detailed error ?

Error : "No such option : -l" when running yt-dlp
12 juin 2022, par garsonI have adapted code from this Stack Overflow answer to try to download a video and use ffmpeg to alter it


yt-dlp "https://www.youtube.com/watch?v=PtkqwslbLY8" -o ffmpeg -i in.mp4 -vcodec libx264 -crf 23 -preset fast -profile:v baseline \
-level 3 -refs 6 -vf "scale=640:-1,pad=iw:480:0:(oh-ih)/2,format=yuv420p" \
-acodec copy output.mp4



However, when I run this I'm getting the error :


yt-dlp: error: no such option: -l



Any ideas of how to fix this ?

12 ffmpeg xfade transitions : "option not found"
17 juillet 2023, par nimdaI'm running into a strange error where each of these following 12 of the 56 xfade transitions are throwing errors :


- 

- hlwind
- hrwind
- vuwind
- vdwind
- coverleft
- coverright
- coverup
- coverdown
- revealleft
- revealright
- revealup
- revealdown


























I've tested all filter transitions with the following command, which is being generated by a nodeJS app with the fluent-ffmpeg library, and only the twelve listed above fail with the same error "option not found" :


ffmpeg -f lavfi -t 169
