At the moment, it's easy to end up with the wrong type of executable because both debug and release produce the same named executable.

I think it should add the "d" suffix to debug builds, as it does with the dlls and libs.

What is an easy way to do this ?

This one goes back to the change that was made at my request, so I guess I have to bear part of the blame :-)

The building of the DebugDLL and ReleaseDLL versions of avcodecgo awry because they try to link in libavutil.lib (libavutild.lib for debug), which are no longer import libraries but static libraries since the import libraries now follow the naming standard saying that import libraries (under Windows) should not have the lib prefix (precisely so that they can be told apart from static library builds).

Thank you for these repositories

I spent monthes trying to compile FFmpeg in windows. I tried cross compile in ubuntu and in mingw but these methods has all kinds of problems.:dizzy_face:

I heared your media project in a programmer chat room by luck.

This is what I'm looking for!!!:smile::heart_eyes:

Hope for batch process

But the bulid process was little stupid: I cloned repositories one by one and opened every solutions to figure out the dependences, then builded librarys once at a time. This takes me one morning.:sweat_smile:

When you pushed to these repositories, I have to pull them one by one again!:sweat_smile:

After realize how stupid I was, I wrote a bash script which works in git bash to pull all the repositories and I'm planning to write MSBuild scripts for VS native tools command prompt.:smirk:

I hope we can add a batch script repository.

Thanks

I had to add ....\libvpx to AdditionalIncludeDirectories. The same with xvid

Possible Fix

Many of the projects (but not all) fail to load in Visual Studio 2015. When loading the project files into the VS editor, you see that some child elements of <ItemGroup> are underlined in blue. Hovering over them then brings up some text saying that Visual Studio cannot understand those tags.

thank you. i need nvdia video codec 7.0 in ffmpeg

When I make a change to one source file, I expect only that file to compile and then the linker to run.
Instead, all files are recompiled.
Do you know how I can correct this?
Thanks

When working closely with FFmpeg builds (read: when stepping into the code with the debugger becomes a habit), having to copy the generated DLLs and .pdb files becomes a source of errors. Currently, building any configuration deletes the output directories, so that you can't keep debug and release builds together without copying them.

ffplay no sound.
x86 or x64.

Your Environment

• Version Used: git 2017-09-05
• Operating System and Version: WIN7X64
• Compiler and Version(s):VS2015

Possible Fix

ffmpeg(native)+sdl(native,pkgconfig), ffplay is OK.

Due to dead code elimination being extensively used throughout FFmpeg code optimisation needs to be enabled in order to remove to dead function calls. Unfortunately this optimisation is not performed in debug builds and so many unresolved external symbols appear. Currently the linker is forced to ignore these symbols but this is a rather dirty hack. Need to find more elegant way to handle this.

My objective is to build ffmpeg within Visual Studio 2015.
I am assuming that the first thing I need to do is to run the project_get_dependencies.bat in the ffmpeg folder, but fails fails to clone the projects.
Running the clone command for all of the projects manually succeeds and they are now next to ffmpeg under my project root.
There are now two problems that are described below.

Context

It is not clear how to acquire all the prerequisites.

Expected Behavior

After following instructions in the project, ffmpeg.sln should build all the components of ffmpeg.

Actual Behavior

1. yasm succeeds to compile some asm files but fails on others. Sample output:

1> Assembling cpuid.asm
1> Assembling emms.asm
1> Assembling fixed_dsp.asm
1> Assembling float_dsp.asm
1> Assembling imgutils.asm
1> Assembling lls.asm
1> Assembling pixelutils.asm

2. Some of the include files required for building are missing. For instance

6>..\libavformat\tls_gnutls.c(24): fatal error C1083: Cannot open include file: 'gnutls/gnutls.h': No such file or directory

Steps to Reproduce

1. clone the ffmpeg project on windows.
2. Install yasm as instructed.
3. In the project run project_get_dependencies.bat
4. clone the projects manually so that they are all next to ffmpeg.
5. open ffmpeg/smp/ffmpeg.sln.
6. Select x64 configuration and rebuild all.

Your Environment

• Version Used:
• Operating System and Version:
  Windows 10 64 bit
• Compiler and Version(s):
  Visual Studio 2015

Possible Fix

It is possible that I am missing a configuration or installation step.
If so, I would like know where to find information on that.

After creating the Visual Studio 2013 projects and compiling them. The include folder under $(OutDir) is missing a header in libavutil/avconfig.h.
This file is included by libavutil/common.h
This file can be found at SMP/libavutil/avconfig.h which is why it is found by the projects in the SMP folder.
However, when I point to the header folder $(OutDir)/include in another project that uses the FFMPEG libraries, the file is not found.
I found that two things needed to be done to fix this:

1. Copy SMP/libavutil/avconfig.h to $(OutDir)/include/libavutil
2. Edit $(OutDir)/include/libavutil/common.h so that it does not include "libavutil/avconfig.h" but rather "avconfig.h".

I cloned the project and opened ffmpeg.sln with Visual Studio 2013
The following projects failed to load: libavcodec, libavdevice, libavfilter, libavformat, libswresample and libswscale.
In addition during compilation a number of headers were not found: zlib.h, sdl.h and a few others.
How can I resolve these?

Hi, can you add "--enable-nonfree and --enable-decklink" to support bmd devices?

Context

can you tell me how to truncate the codec library

Expected Behavior

Because i don't neet some decoders and encoders,so i want to truncate the codec library

I don't know how to truncate the codec library

any reason ?

hello, I compile shiftmediaproject ok, then test hls segment, command likes:
ffmpeg.exe -i F:\web\express\testv\public\hls\ani.mp4 -codec:v libx264 -codec:a aac -map 0 -f ssegment -segment_format mpegts -segment_list F:\web\express\testv\public\hls\playlist.m3u8 -segment_wrap 5 -segment_time 5 F:\web\express\testv\public\hls\out%%03d.ts

but when I preview m3u8 in browser , I found that video is blocked frequently； I notice that ts（segemnt）file was produced very slowly。 if I use ffmpeg complied by mingw， ts file was produced very fast， any suggestion？

thanks a lot。

Thank you!

The above error can only be worked around by creating a subdirectory libass below the msvc output directory and copying all the header files of the libass library there. Unfortunately, that subdirectory gets deleted by the building process sometimes.

When I try to run the project generate to make new project files it throws an error, I assume it has to be that I don't have all the dependencies downloaded but its not super clear which ones

I'm getting the following in log.txt when calling my version of project_generate.bat (I simply added --disable-sdl):

alldevices.c
avdevice.c
utils.c
dshow_crossbar.c
dshow.c
dshow_enummediatypes.c

opengl_enc.c
vfwcap.c
file_open.c
../../..\libavdevice\opengl_enc.c(43): fatal error C1083: Cannot open include file: 'GL/glext.h': No such file or directory

This should not happen, because I have downloaded glext.h, and put it into D:\Libraries\include, which I have configured via the Property Pages in Visual Studio.

This is not a bug, and it may have nothing to do with FFmpeg. Nevertheless, I'd appreciate any input on this problem.

Our application, which is 32-bit, requires quite a bit of memory. However, it's not its needs of physical memory (those are below 1GB) that present the problem, but the fact that the per-process 2GB address space is exhausted.

I was able to determine this using Mark Russinovich's excellent VMMap tool. VMMap also showed me that a lot of the address space is being wasted on the stacks: roughly 500MB are reserved for the stacks of 12 threads - only 5MB being actually used (both numbers are totals over all threads). It's quite probable that the actual consumption would have gone up a bit if the creation of the video stream had succeeded (which it didn't because memory allocation failed), but I suspect the actual need is nowhere near as high as the reserved amounts.

I'm not sure why our exe is reserving that much stack; it might be because of a VS project setting that I can't check myself at the moment. But if it turns out, as I think is the case, that we do need a lot of stack for the main thread, is there a way to set a specific stack size for the threads created by FFmpeg ?

Now we get all outputted to "msvc". Useful to have separate directories for each configuration.

The important variables - other than platform (already take care)

• $(Configuration)
• $(PlatformToolset)

like - msvc-v141\Debug\x86

Hi Matthew Oliver,
first let me tell you how thankfull I am that you share all your work necessary for porting ffmoeg and its libraries to VS. That was extremely helpfull for me!

Have you had a look at "libaom", the library that provides the new AV1 video codec? I believe it is an important addition to ffmpeg.

It was actually easy to build the aom-project with VS using the cmake option in VS-2017.
Unfortunately the "CMakeLists.txt" file produces only *.exe files, since all the libraries in the project seem static. I am certain that it is possible and maybe easy to do the same with dynamic libraries, but I do not have the slightest idea, how to modify a cmake-file.

Do you have any plans to integrate libaom into the ShiftMediaProject collection of libraries?
Best regards, Peter

Sorry if this is the wrong repo to post this in, Would it be possible for you to create a libopenh264 project that can then be used with this FFMPEG project?

Hi All,

I cloned the code and configured on Visual Studio 2017 with Window SDK (10.0.17763.0) on Windows 10 Prof.

While build the project then I got compilation error.

Context

I need latest version of of FFmepg4.XX in for some testing. If am download from the FFmpeg.org then these methods(ff_rtsp_parse_line & ffio_open_dyn_packet_buf) are missing while creating 'obj' file.

Expected Behavior

Code should compile smooth without error

Actual Behavior

But we are getting error. Log file attached
ffmpeg.log

Steps to Reproduce

1. Checkout the the code and its dependency
2. Open 'ffmpeg_deps.sln' in Visual Studio C++
3. Build the Solution
4. You will receive error

Your Environment

Machine OS: Windows 10 Prof
Visual Studio C++ : 2017
Windows SDK : 10.0.17763.0

I'm trying to compile the project using Visual Studio 2017, but it fails with linker errors. I was able to successfully compile the project using Visual Studio 2015 on a different machine, using the same steps.

Context

FFmpeg should be able to compile using Visual Studio 2017.

Expected Behavior

Successful compilation.

hi, i use this command to generator new project with enable fdk-aac lib, but it always come with this error msg:

Error: Failed calling temp.bat. Ensure you have Visual Studio or the Microsoft
compiler installed and that any required dependencies are available.
See log.txt for further details.

the command is :

I want to cancle x264 library becasue my project is depends x264.lib

This is not a priority to me, because I just found out that I can't use that particular configuration.

Like the heading says, the DLL is generated due to the /FORCE option, but the import library isn't, probably because of all the linker errors.

Regarding the import library, I'd also like to suggest a change. There is standard (not a very intuitive one, but still) stating that (under Windows) only static libraries should carry the lib prefix, while DLL import libraries shouldn't (i.e. they should have the same name as the DLL whose interface they represent).

(This is stated in the Boost project. Actually the naming convention followed by Boost is even more involved, but personally I'm not suggesting you should follow that, only the prefix part.)

With your current approach, you have to configure separate output directories for each configuration, otherwise the import and static libraries will overwrite each other.

Also, minor detail: the default output directory seems to be "msvc", but I think your readme says it is either "msvc32" or "msvc64".

Great project by the way.

1. libspeex.def - LIBRARY labelled as libspeex not speex, meaning ffmpeg won’t start as it tries to load the libspeex.dll library instead of speex.dll

2. I encountered issues with libvpx.def mentioned elsewhere where I had to remove the DATA tags.

3. It’s necessary to install YASM in addition to NASM for several projects to build.

4. speex_header_free comes up as unresolved for libavcodec until I added it manually to libspeex.def

5. Had to install the header file from here https://github.com/KhronosGroup/EGL-Registry/tree/master/api/KHR into a KHR include folder for the opengl stuff to build.

Think that’s about it. Only built ReleaseDLL of ffmpeg so not sure if other issues lurk when I build Debug.

This was all with VS2017 on Win 10 and latest git clone of the project.

I retargeted all projects to the latest Win10 SDK via ffmpeg_deps.sln

Using the default project configuration, udp (for example when streaming over rtp) complains that pthreads support is required for circular buffers. Can this be solved with any config option? Or do I have to include pthread-win32 as a dependency?

I tried various ways to get the current version to compile, but no luck. With the static version, I had countless linker errors for symbols beginning with "ff". To my understanding, those are the entry points for the codecs, so those cannot be ignored.

In desperation, I tried a debug DLL build, but that build fails with the above linker error (no DLL is generated).

There is also a serious problem with yasm. Although I obtained version 1.3 and took the configuration steps outlined in your readme, yasm stills fails:

Error 1 error MSB3721: The command "vsyasm -Xvc -f win32 -g cv8 -i "..\\" -i ".\\" -i "..\libavcodec" -o "D:\SourceLibs\ShiftMediaProject\Sources\FFmpeg\SMP\\obj\DebugDLL\Win32\libavutil\\" -P "config.asm" -rnasm -pnasm "D:\SourceLibs\ShiftMediaProject\Sources\FFmpeg\libavutil\x86\cpuid.asm"" exited with code 1. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\BuildCustomizations\vsyasm.targets 45 5 libavutil

I've had similar errors throughout the project. In most cases, I was able to work around them by going to "Build customizations" and switching from yasm to masm, but not here.

Your Environment

• Version Used: git 2017-09-05
• Operating System and Version:WIN7X64
• Compiler and Version(s):VS2015+YASM1.3

Possible Fix

I had some tests with ffmpeg binaries from shiftmedia and zeranoe.

• ffmpeg-3.4.2-win64-shared.zip (zeranoe)
  https://ffmpeg.zeranoe.com/builds/win64/shared/
• 3.4.2.r90885 (shiftmedia)
  https://github.com/ShiftMediaProject/FFmpeg/releases

Here are test commands and results.

1. ffmpeg -buildconf

• zeranoe
  

• shiftmedia
  

2. ffmpeg -i song.mp4 -vcodec mpeg4 -an -threads 6 output.mp4 (with and without -threads option, zeranoe is faster in every case..)

• zeranoe
  

• shiftmedia
  

Above results shows that

• two binaries are built with different config options and compilers.
• shiftmedia ffmpeg is slower than zeranoe`s.

I want to know correct reason what makes it slower.

• Which config option makes slower?
• FFmpeg built in msvc is slower than one built in gcc compiler?

Please check and let me know your ideas.

Thanks!

diff --git a/SMP/ffplay.vcxproj b/SMP/ffplay.vcxproj
index be4cdafd8d..7e04a7a508 100644
Original: $(OutDir)\bin\x64$(TargetName)$(TargetExt)
FIXED: $(OutDir)$(TargetName)$(TargetExt)

Sorry for not using the issue template, because it's a little issue i think.
