[FFmpeg-devel] [PATCH]Fixed av_fast_realloc calling error when compiled to the Dynamic library

[杨超]

Hello,Michael:Sorry for my late reply.>the patch lost the \nyes, the patch lost \n.
the patch is :---a/libavcodec/utils.c+++b/libavcodec/utils.c@@ -127,1 +127,1 @@-#if FF_API_FAST_MALLOC && CONFIG_SHARED && HAVE_SYMVER+#if FF_API_FAST_MALLOC && (!CONFIG_SHARED) && HAVE_SYMVER
>what error message(s) do you get when it fails ?The command line is:"./ffmpeg -y -i ./test.mp4 -vcodec copy -acodec copy -vbsf h264_mp4toannexb -strict -2 -f hls test.m3u8"The fails Phenomenon is feign death( Not occurred hang up or segment fault ).I debugged the dynamic library using gdb(a android mobile phone) and gdbserver(utuntu) and found when calling av_fast_realloc. The fails occurred.So I modified this bug as the patch and tested it(other processings on android plantform). The result is OK.The reason about this bug is using the macro “FF_SYMVER” on cross compile platform. Thank you for your reply.
