You can pass the payload section of the RTP packets directly to an opus decoder to convert to PCM float or integer samples. To save it in a file other audio

Opus Raw Pakcets
Hi, I have application, where I am reciving the RTP packets, which has OPUS payload. >From the RTP packets I got following information: (12 byes Header) tells about the version, payload time, time stamp, srsc, etc. The rest of the packet is OPUS payload (raw format), The TOC byte from OPUS payload tells its 20ms frame, even the time stamp different of 960 means 20 msec frame. Questions: 1)

[net-next RFC] pktgen: don't wait for the device who doesn't free skb immediately after sent
...do not free the old tx skbs immediately after it has been sent (usually in tx interrupt). One such example is virtio-net which optimizes for virt and only free the possible old tx skbs during the next packet sending. This would lead the pktgen to wait forever in the refcount of the skb if no other pakcet will be sent afterwards. Solving this issue by introducing a new flag IFF_TX_SKB_FREE_DELAY which could notify the pktgen that the device does not free skb immediately after it has been sent and let it not to wait for the refcount to be one.
