a)
Which is not what the original poster requested.

On the other hand, the command line needs to be adapted anyway,
depending on hwaccel. Perhaps one could use ffmpeg to query by doing
trial and error (e.g. encoding to /dev/null) - unfortunately, ffmpeg
won't say what the actual issue was, unless you want to parse log
messages.
