swscaler warning : deprecated pixel format used

Question

I want to perform a color space conversion of my video frame before converting it to an opengl texture with the following code: ``` struct SwsContext * pSwsCtx = sws_getCachedContext(NULL,width, height, codec->pix_fmt, width, height, AV_PIX_FMT_RGBA, SWS_POINT, NULL, NULL, NULL); ``` Each time the sws_getCachedContext() function is called I got the following warning: ``` [swscaler @ 0x10506fa00] deprecated pixel format used, make sure you did set range correctly ``` Here is my ffmpeg output for version information: ``` ffmpeg version 2.2 Copyright (c) 2000-2014 the FFmpeg developers built on Mar 26 2014 15:29:01 with Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn) configuration: --prefix=/usr/local/Cellar/ffmpeg/2.2 --enable-shared --enable-pthreads --enable-gpl --enable-version3 --enable-nonfree --enable-hardcoded-tables --enable-avresample --enable-vda --cc=clang --host-cflags= --host-ldflags= --enable-libx264 --enable-libfaac --enable-libmp3lame --enable-libxvid liba…

Accepted Answer

It seems you're trying to read `AV_PIX_FMT_YUVJXXXP` frames which are deprecated (see the libav doc). You can use this workaround to manage it :

```
AVPixelFormat pixFormat;
switch (_videoStream->codec->pix_fmt) {
case AV_PIX_FMT_YUVJ420P :
    pixFormat = AV_PIX_FMT_YUV420P;
    break;
case AV_PIX_FMT_YUVJ422P  :
    pixFormat = AV_PIX_FMT_YUV422P;
    break;
case AV_PIX_FMT_YUVJ444P   :
    pixFormat = AV_PIX_FMT_YUV444P;
    break;
case AV_PIX_FMT_YUVJ440P :
    pixFormat = AV_PIX_FMT_YUV440P;
    break;
default:
    pixFormat = _videoStream->codec->codec->pix_fmts;
    break;
}
```
