Looking at the code, this is just av_fast_realloc. You could change it to that, or you could just allocate MAX_PAGE_SIZE at the start and never reallocate. Its only 65k. Up to you, feel free to commit whatever you choose. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
