These functions have a terrible design, let us fix them before extending them. First design mistake: no error code. A helper function for testing memory allocation failure where AVERROR(ENOMEM) does not appear is absurd. Second design mistake: printing a message. Return the error code, let the caller print the error message. Third design mistake: hard-coded use of goto. http://ffmpeg.org/pipermail/ffmpeg-devel/2020-May/262544.html Signed-off-by: Limin Wang <lance.lmwang@gmail.com>
