* WebP encoder: use WebPAnimEncoder API when available.Urvang Joshi2015-05-23
| | | | | | | | | | | | | | | | | | 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>

| * hevc: make avcodec_decode_video2() fail if get_format() failswm42015-05-19
| | | | | | | | | | | | | | | | | | | | | | | | Personally, I need the decoder to back out if get_format() returns no usable pixel format. This didn't work because the error code was not propagated down the call chain. This in turn happened because the variable declaration removed in this patch shadowed the variable, whose value is returned at the end of the function. Consequently, failures of decode_nal_unit() were ignored in this place. Reviewed-by: Andreas Cadhalpun <andreas.cadhalpun@googlemail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
