FFmpeg : how to make video out slides and audio
7 juillet 2014, par Muhammad UmerSo i have several images some png and some jpgs. And i have mp3 audio. I want to make a video file don’t care what format.
So i want either :
A video made up of xyz size meaning images are centered and cropped if they go beyond dimensions coupled with audio in mp3 format..
I have tried copying and pasting things and even modifying them after reading documents but in the end i got a blank video with audio and huge file that took forever to complete.

ffmpeg trim videos at specific start / end frame [closed]
13 mai 2023, par emilectorI have mp4 video files that I need to trim between a start and an end frame. I am using this python command, but instead of the trimmed videos I get long videos of the same frame.


os.system('ffmpeg -i {0}.mp4 -vf trim=start_frame={1}:end_frame={2} -fflags +genpts {3}.mp4'.format(inputVideoPath, startFrame, endFrame, outputVideoPath))



I dont care about audio. Could someone point me in the right direction ?

Is there a set of working P/Invoke declarations for FFMpeg, libavutil, libavformat and libavcodec in .NET ?
11 février 2014, par casperOneI'm currently looking to access libavutil, libavformat and libavcodec (all part of FFMpeg) from .NET.
Currently, I'm getting the libraries from the automated builds of the shared FFMpeg package performed every night for Windows 32-bit.
I am also using the code from the ffmpeg-sharp project. In that project, I have removed a number of classes that were not compiling (they are wrapper classes not the P/Invoke declarations).
The code compiles fine, but I am running into a few issues.
First, it appears that the build of av*.dll uses the cdecl calling convention, as I was receiving a number of
PInvokeStackImbalanceException
when trying to callav_open_input_file
. This was easy enough to change to get it to work right. TheAVFormatContext
structure is populated.After that, I want to call
av_find_stream_info
to get information about the streams in the file. However, when calling that with theAVFormatContext
retrieved from the call toav_open_input_file
, anAccessViolationException
is thrown indicating that I am trying to read or write from protected memory.Has anyone used P/Invoke to access the libavutil, libavformat and libavcodec dll libraries through P/Invoke and have gotten it to work ?
I should mention that working with the command-line version of FFMpeg, while a solution, is not a viable solution in this case, access needs to occur through the libraries. The reason for this is that I'd have to thrash the disk way too much to do what I need to do (I have to do a frame-by-frame analysis of some very high definition video) and I want to avoid the disk as much as possible.
