D port of the FFmpeg C headers

ffmpeg-d's Issues

When linking with this depended on, LD fails.

ld: unknown option: -pthread
clang: error: linker command failed with exit code 1 (use -v to see invocation)
--- errorlevel 1

That's what happens on my MBA 2013 running OS X 10.11.2.
Here's my LD version.

ld -v
@(#)PROGRAM:ld  PROJECT:ld64-253.9
configured to support archs: armv6 armv7 armv7s arm64 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em (tvOS)
LTO support using: Apple LLVM 7.0.2 (clang-700.1.81)

I did some research. Apparently pthread is not supported everywhere. It is hard to find info on. Perhaps that is true for OS X too?

This only happens when depending on ffmpeg-d.

ffmpeg-d project versioning

Hey, I've started work on porting the headers over from 3.0.2 and I was just wondering what should happen with the version of this project. I don’t really was to push a breaking change to master right now for obvious reasons.

I think we should be matching the major.minor but have our own patch from ffmpeg so users know what to use and can set the correct version in dub.

Also it would be nice to have separate branches in this repo for each version so we can add changes to older releases. (2.8 will probably hang around for a while)

So what I propose is matching the main ffmpeg repo by adding these branches added to this repo:

• release/2.8
• release/3.0
• release/3.1

And then in the readme for each branch state what version it applies to and the fact that other branches are available with a code snipit on how to add to dub and lock the major.minor version.

So something like this:

---

NOTE: This branch is compatible with ffmpeg 3.0.x, for other versions please see the other branches for usage information.

To include ffmpeg-d in your dub project add the following dependency to your dub.json file.

"ffmpeg-d": "~>3.0.0"

What are your thoughts?

Also, feel free to have a read through my 3.0.2 port at DavidBennettPIO@ccb16d2 I still need to test this out well, If I have time I might even write some simple examples.

Thanks!

How do I use it?

Could you please provide sample code in the README?

@nogc nothrow are missing

Error: function ffmpeg.libavformat.avformat.AVIndexEntry.flags(int v) cannot be overloaded with another extern(C) #121

see libmir/dcv#121

default configuration should be defined

currently posix test configuration is used for instead of default

sws_scale reports null value

if(rawFrame.data.ptr == null || rawFrame.linesize.ptr == null || convertedFrame.data.ptr == null || convertedFrame.linesize.ptr == null) return;
                    sws_scale(imageConversionContext, (cast(AVPicture*)rawFrame).data, (cast(AVPicture*)rawFrame).linesize, 0, cameraCodecContext.height, (cast(AVPicture *)convertedFrame).data, (cast(AVPicture *)convertedFrame).linesize);

As you can see, the code checks for any null values.

[swscaler @ 0x7f9bc10ba000] One of the input parameters to sws_scale() is NULL, please check the calling code

Why is this happening? Thanks in advance.

FFMPEG version 2.7.6
