[FFmpeg-devel] [RFC] check avcodec_open codec paramert != NULL

[Reimar Döffinger]

Hello,
I personally would prefer if the avcodec_open would check if codec is
NULL and return an error then.
The main reason is laziness: You can then just do
avcodec_open(vf->priv->avctx, avcodec_find_encoder(CODEC_ID_PNG))
instead of having an extra variable for the avcodec_find_encoder result
and checking it against NULL.
What do you think? I admit it encourages sloppy error checking but I
just hate doing more checks that absolutely necessary, it clutters the
code too much for my tastes.

Greetings,
Reimar D?ffinger
