[FFmpeg-devel] [PATCH 0/4] av_warn_unused_result for avutil/eval

[Ganesh Ajjanagadde]

This is an attempt on my end to be more systematic and avoid sloppiness and noise
while sending patches. As can be seen, I have made use of the cover letter
option and have organized an av_warn_unused_result change into one cohesive unit:

1/4 fixes issues of unchecked error codes from av_expr_parse_and_eval, essentially
ENOMEM.

2/4 fixes an issue I noticed while working on vf_rotate regarding the above.

3/4 cleans up issues in the test build for avutil/eval, so that 4/4 which adds
av_warn_unused_result does not cause warning regressions.

Tested with FATE.
--------------------------------------------------------------------------------
Please reply to this cover letter if you think my attempt at more structured changes
is an improvement over e.g mass av_warn_unused_result changes.

Ganesh Ajjanagadde (4):
  avfilter/all: check and propagate the return code of
    av_expr_parse_and_eval
  avfilter/vf_rotate: correct log message
  avutil/eval: check av_expr_parse_and_eval error code in the test build
  avutil/eval: add av_warn_unused_result
