Comment (by H2Swine):

 Looks like remuxing hits another size constraint. 487 823 229 bytes remux
 fine,  947 942 263 bytes and it throws this error:
 {{{
 [in#0/mov,mp4,m4a,3gp,3g2,mj2 @ 00000211d3001680] Error during demuxing:
 Cannot allocate memory
 [out#0/mp4 @ 00000211d30125c0] video:0KiB audio:0KiB subtitle:0KiB other
 streams:0KiB global headers:0KiB muxing overhead: unknown
 [out#0/mp4 @ 00000211d30125c0] Output file is empty, nothing was encoded
 }}}

 (Primarily used by ... people who throw another codec into testing. ALS
 does surprisingly good on some signals.)
