I am using ARM processor (DM8168). The total memory available is 256 MB. Also, there are several other processes going on in the system like live streaming of 4 streams.
In this scenario system does not always have enough memory to support 138 MB allocation.

Currently (since nearly ten years), FFmpeg assumes a theoretical maximum size for one macroblock of 3000 bytes (see libavcodec/mpegvideo.h line 75). A small overhead for safety is added in libavcodec/mpegvideo_enc.c line 1702. Could you explain your usecase? I would assume that on a modern system where you want to encode 4k a 100 MB allocation (that does not leak) is no problem or am I wrong?
