yes, after thinking about this for a second ...
the 0x1b7 should be sent to the decoder as its own packet and the decoder
should if needed then output the last frame (as if it has been feeded with
a 0 sized packet at the end)

something like:

-    if (buf_size == 0) {
+    if (buf_size == 0 || !memcmp(buf, (char[]){0,0,1,BF}, 4) {
        /* special case for last picture */
        if (s2->low_delay==0 && s2->next_picture_ptr) {

Today you'd get arrested for mere telling someone where the library is
