Hey guys, I just want to confirm if webp decode is not supported yet? I build ffmpeg and enabled as many libraries as I can like:
> ./configure --prefix=/usr/local --enable-gpl --enable-nonfree > --enable-libass --enable-libfdk-aac --enable-libfreetype > --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis > --enable-libvpx --enable-libx264 --enable-libxvid --enable-libwebp > --enable-demuxer=webp_pipe --enable-decoder=webp > --extra-ldflags=-L/usr/local/lib --extra-cflags=-I/usr/local/include but then I do this: *./ffmpeg -i test.webp -vframes 1 frame.jpg * want to extract 1 frame from webp animated image. I still got the error like: > ffmpeg version N-80121-gbe96ebd Copyright (c) 2000-2016 the FFmpeg > developers > built with Apple LLVM version 7.3.0 (clang-703.0.31) > configuration: --prefix=/usr/local --enable-gpl --enable-nonfree > --enable-libass --enable-libfdk-aac --enable-libfreetype > --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis > --enable-libvpx --enable-libx264 --enable-libxvid --enable-libwebp > --enable-demuxer=webp_pipe --enable-decoder=webp > --extra-ldflags=-L/usr/local/lib --extra-cflags=-I/usr/local/include > libavutil 55. 24.100 / 55. 24.100 > libavcodec 57. 43.100 / 57. 43.100 > libavformat 57. 37.101 / 57. 37.101 > libavdevice 57. 0.101 / 57. 0.101 > libavfilter 6. 46.100 / 6. 46.100 > libswscale 4. 1.100 / 4. 1.100 > libswresample 2. 0.101 / 2. 0.101 > libpostproc 54. 0.100 / 54. 0.100 > [webp @ 0x7fb023801c00] skipping unsupported chunk: ANIM > [webp @ 0x7fb023801c00] skipping unsupported chunk: ANMF > Last message repeated 793 times > [webp @ 0x7fb023801c00] image data not found > [webp_pipe @ 0x7fb023800a00] decoding for stream 0 failed > [webp_pipe @ 0x7fb023800a00] Could not find codec parameters for stream 0 > (Video: webp, none): unspecified size > Consider increasing the value for the 'analyzeduration' and 'probesize' > options > Input #0, webp_pipe, from 'test.webp': > Duration: N/A, bitrate: N/A > Stream #0:0: Video: webp, none, 25 tbr, 25 tbn > [buffer @ 0x7fb022f00120] Unable to parse option value "0x0" as image size > [buffer @ 0x7fb022f00120] Unable to parse option value "-1" as pixel > format > [buffer @ 0x7fb022f00120] Unable to parse option value "0x0" as image size > [buffer @ 0x7fb022f00120] Error setting option video_size to value 0x0. > [graph 0 input from stream 0:0 @ 0x7fb022f00060] Error applying options > to the filter. the code here http://ffmpeg.org/doxygen/trunk/webp_8c_source.html#l01503 <http://www.google.com/url?q=http%3A%2F%2Fffmpeg.org%2Fdoxygen%2Ftrunk%2Fwebp_8c_source.html%23l01503&sa=D&sntz=1&usg=AFQjCNGh_NjDELvCWUU2iOx4pyX7vI1ikA> shows the ANMF chunk been skipped? does that mean I cannot extract frame from webp using ffmpeg for now? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
