I was trying to update my application to FFmpeg 3.0 but I couldn't get it work.
To see what was going on I was trying to run the decoding_encoding.c example, and I keep getting an error, even though I don't change anything meaningful.
The function returning an error is
avcodec_open2(c, codec, NULL);
with returned value -22.
On the console I receive the following message:
Could not open codec
[libx264 @ 0000000000597180] Specified pixel format -1 is invalid or not supported
c->pix_fmt is AV_PIX_FMT_YUV420P;
I tried it as well with the latest snapshot, but the error remains. I am using windows 7 64 bit, the libraries I am using are the ones retrieved from zeranoe.
Any idea of what am I doing wrong?
