ffmpeg : "invalid syntax" on file name ?
26 novembre 2017, par Josh FloriI am trying to use this line of code in python :
ffmpeg -i test.mp4 -vf fps=1 out%d.png
per the documentation here https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video
but python is giving me :
File "<stdin>", line 1
ffmpeg -i test.mp4 -vf fps=10 out%d.png
^
SyntaxError: invalid syntax
</stdin>I have imported ffmpeg and have my test.mp4 file exactly where I keep everything else python related. I have looked for a good while and am not sure what I am doing wrong, seems like it should be something simple ? Any ideas ?
Thanks

FFMPEG Dash libvorbis page samples error
9 mai 2015, par BrittelWhen using the guide http://wiki.webmproject.org/adaptive-streaming/instructions-to-playback-adaptive-webm-using-dash to encode several webm streams the audio stream is not correctly encoded by ffmpeg.
ffmpeg -i input_audio.wav -c:a libvorbis -b:a 128k -vn -f webm -dash 1 audio_128k.webm
When creating the manifest and loading the stream into ExoPlayer (but the same problem occurs in the reference javascript implementation dash.js), the error states :
[...] SoftVorbis.cpp:314 CHECK_GE( inHeader->nFilledLen,sizeof(numPageSamples)) failed: 1 vs. 4
The stream works flawlessly when not including the audio stream in the manifest.
I’m using ffmpeg version 2.5.6-0ubuntu0.15.04.1
Does anyone know what the problem might be ?

ffmpegthumbnailer issue : dyld : Library not loaded : /usr/local/lib/libavutil.52.18.100.dylib
18 octobre 2013, par scientifficWhen I try to run ffmpegthumbnailer, I get the following error :
dyld: Library not loaded: /usr/local/lib/libavutil.52.18.100.dylib
Referenced from: /usr/local/bin/ffmpegthumbnailer
Reason: image not found
Trace/BPT trap: 5I installed ffmpeg using the directions here :
http://ffmpeg.org/trac/ffmpeg/wiki/MacOSXCompilationGuide
In my /usr/local/lib folder, I have the file "libavutil.a", but not the one specified in the error mesage.
How can I solve this error ?
This is what I was using to try to generate a thumbnail :
ffmpegthumbnailer -i /public/uploads/tmp/1382121359-37490-7826/thumb_Untitled.mov -o /public/uploads/tmp/1382121359-37490-7826/tmpfile.png -c png -q 10 -s 158
