[FFmpeg-devel] [PATCH 1/2] avutil/internal: Add ff_elog()

[Michael Niedermayer]

This enables the extra error messages in case of DEBUG or high assrtion levels.
High assertion levels imply slow checks in inner loops so any extra error should
be insignificant.
Is it preferred to have a separate switch for ff_elog() so it doesnt depend on
DEBUG/assertion level ?
