Hello, I'm working at the Austrian Mediathek (national audio/video archive) and together with other archives we are using FFv1 as our archival video codec.
There have been major updates to FFv1, and its version 3 (FFv1.3) is nearing its release. I've tried to merge the code from ffmpeg to the current git-head of libav, but I'm still running into compile errors: //------------------ libavcodec/ffv1.c: In function ‘encode_slice’: libavcodec/ffv1.c:1245:13: warning: passing argument 2 of ‘put_rac’ from incompatible pointer type [enabled by default] libavcodec/rangecoder.h:82:20: note: expected ‘uint8_t * const’ but argument is of type ‘int *’ libavcodec/ffv1.c: In function ‘encode_frame’: libavcodec/ffv1.c:1286:5: error: implicit declaration of function ‘ff_alloc_packet2’ [-Werror=implicit-function-declaration] libavcodec/ffv1.c: In function ‘decode_slice’: libavcodec/ffv1.c:1680:13: warning: passing argument 2 of ‘get_rac’ from incompatible pointer type [enabled by default] libavcodec/rangecoder.h:110:19: note: expected ‘uint8_t * const’ but argument is of type ‘int *’ libavcodec/ffv1.c:1709:9: warning: passing argument 2 of ‘get_rac’ from incompatible pointer type [enabled by default] libavcodec/rangecoder.h:110:19: note: expected ‘uint8_t * const’ but argument is of type ‘int *’ libavcodec/ffv1.c: In function ‘decode_frame’: libavcodec/ffv1.c:2104:49: error: ‘AVCodecContext’ has no member named ‘pkt_timebase’ libavcodec/ffv1.c:2105:85: error: ‘AVCodecContext’ has no member named ‘pkt_timebase’ libavcodec/ffv1.c:2118:36: warning: cast discards ‘__attribute__((const))’ qualifier from pointer target type [-Wcast-qual] libavcodec/ffv1.c:2136:53: warning: to be safe all intermediate pointers in cast from ‘uint8_t **’ to ‘const uint8_t **’ must be ‘const’ qualified [-Wcast-qual] cc1: some warnings being treated as errors //------------------ As I'm not familiar with the code structure of neither ffmpeg nor libav, I'd be happy if anyone here could help me out, so libav can support this important format, too.
