Libavcodec "the procedure entry point for av_frame_alloc could not be located" error in Visual Studio 2017 C++ project
25 novembre 2019, par AvesI am trying to use libavcodec from ffmpeg library in C++ with Visual Studio 2017 Community. I downloaded the latest x64 dev and shared builds from zeranoe (version 20171217), set up include directories and additional libraries in Visual Studio for x64 build, added DLL files from shared package to my PATH.
This is my sample test code :
extern "C" {
#include
}
int main() {
avcodec_register_all();
AVFrame *pAvFrame = av_frame_alloc();
av_frame_free(&pAvFrame);
return 0;
}The code compiles without problems but when I run the application I see a dialogue window with error message "the procedure entry point for av_frame_alloc could not be located in DLL" (actual message is not in English, this is the translated version).
I tried to set Linker->Optimization->References to /OPT:NOREF as it was advised in the similar questions but it did not help.
Dependency walker shows that av_frame_alloc is exported, "Entry Point" is not bound. A little bit strange is that av_frame_alloc is displayed in both avcodec-58.dll (as red) and avutil-56.dll (as green). Maybe the reason is that the application is trying to get this function from avcodec instead of avutil, but I’m not sure, since I did not check the source code of these libraries.
So the question is how to set up such a simple FFMPEG-based C++ project in VS2017, where I’m wrong ?
UPD. 1.

Revision 452dc21500 : Move input frame scaling into the recode loop Move the point at which input fra
3 octobre 2014, par Adrian GrangeChanged Paths :
Modify /vp9/encoder/vp9_encoder.c
Modify /vp9/encoder/vp9_encoder.h
Modify /vp9/encoder/vp9_firstpass.c
Move input frame scaling into the recode loopMove the point at which input frames are scaled
into the recode loop. This will allow us to change
the coded frame size dynamically in response
to previous attempts to encode the frame at a
higher resolution.A following patch will implement a scheme for
resizing the frame in the recode loop.Change-Id : I6a59c02d6ac1626512edad6de8b60063b79433e6

Looking to play back non-encoded video upload then export gif from selection point via FFMPEG
10 novembre 2019, par Christopher NeilWe’ve been trying to crack this code all week, reaching out to everyone to see if you have any solutions ?
- We want the user to upload a video and in the next step he will select a small 5 second loop of the video which will be made as a gif.
- Old developer was able to do this by splicing the video at 10 seconds instead of 5 but not re-encoding it meant that it would sometimes be beyond 12 seconds and in some cases less than 7.
- We changed the code to force keyframes with re encoding so that it splices the video at exactly 5 seconds to show the loop.
- These slices are shown to the user using html5 video player.
- Upon selection of the loop that sliced video is converted to gif.
Everything is working in the vice order. The issue is when the user uploads a large sized and length video this slicing and re-encoding takes forever and that cause the user to feel the site is not working properly.
What we want is very simple :
- Show 5 second portion of the video on loop.
- If user wants to select another loop he/she clicks the next button and is taken to the next 5 second loop which would be either at 25% of the video or some other
- On selection of that portion it converts it into gif.
