Le decadi 20 pluviôse, an CCXXII, Michael Niedermayer a écrit :
> Makefile:111: target `tools/uncoded_frame' doesn't match the target pattern

Fixed using:

+PROGS += tools/uncoded_frame$(PROGSSUF)$(EXESUF)

Hopefully fixed.

The segfault would happen whenever the input graph could not be initialized,
due do clean-up on an array that was not yet allocated. That is fixed.

It fails with any file that has just audio because you kept ":s=v+a", and
there is no video stream.

New patch attached, thanks for the testing.
