PCM being encapsulated in packets with "proprietary" header values to me also sounds like the task for a demuxer. The "codec" underneath, once the overhead is stripped, looks like plain PCM again, right? > the 3rd option is a AVParser to take the output from the wav > demuxer and turn it into properly packetized data Would that be like an input-bitstream filter?
