James Almer	57d9788d1b	configure: simplify libwebp checks The libwebpmux pkg-config file already has an explicit dependecy on libwebp >= 0.2.0. Also remove the warning and silently disable the anim encoder when libwebpmux is not new enough.

Urvang Joshi	02cf59f3a6	WebP encoder: use WebPAnimEncoder API when available. WebPAnimEncoder API is a combination of encoder (WebPEncoder) and muxer (WebPMux). It performs several optimizations to make it more efficient than the combination of WebPEncode() and native ffmpeg muxer. When WebPAnimEncoder API is used: - In the encoder layer: we use WebPAnimEncoderAdd() instead of WebPEncode(). - The muxer layer: works like a raw muxer. On the other hand, when WebPAnimEncoder API isn't available, the old code is used as it is: - In the codec layer: WebPEncode is used to encode each frame - In the muxer layer: ffmpeg muxer is used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
