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

Any idea to disable this warning? How to set the color range correctly?
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;
}
