Subject: [PATCH] avcodec/libaom: fix setting amount of threads
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The libaom doxy says that a value of 0 for the threads fields is
equivalent to a value of 1, whereas for avctx->thread_count it means
the maximum amount of threads possible for the host system.
Use av_cpu_count() to get the correct thread count when auto threads
is requested.
