Invalid option error using avcodec_open2 and libopus

Question

I'm getting an invalid option result from avcodec_open2 in ffmpeg 3.1.6 with libopus 1.1.4. I've sorted through all the options and I cannot locate the offending option, I created a gist holding the relevant native code. I've searched all about the internet and cannot find anything helpful as of yet. I've also tried with and without the opts dictionary.

results = avcodec_open2(context, codec, &opts);

and

results = avcodec_open2(context, codec, 0);

All tests and variations return -22 (at line 51 in gist)

memset(context, 0, sizeof(context));

That code needs to be removed. It will basically break everything. Specifically, it will unset all things set in avcodec_alloc_context3() based on the codec parameter, as well as more generally all codec-agnostic defaults.

(Note that it only zeroes the first 8 (on x86-64) bytes, since you used sizeof(context) instead of sizeof(*context)).

I have removed the offending line; thank you. However, the code sill doesn't work. – Paul Gregoire May 12 '17 at 14:47

At that point, your stderr should tell you which priv options are missing when you call avcodec_open2() with a non-NULL opts. – Ronald S. Bultje May 12 '17 at 21:36
