Hi, On Thu, Feb 16, 2017 at 06:19:00PM +0000, Rostislav Pehlivanov wrote: > > > > No, do this in libavfilter and do not introduce another useless pseudo > > codec > > > > *libavformat, sorry The advantage of using a pseudo codec just to depack the stream is that the input and the codec are in separate threads in ffmpeg, so it can handle a heavier workload. Is there any way to do the depacking in the RTP handler without that performance penalty? Thanks,

Add a codec capable of decoding some formats of the RFC4175. For now it's only capable of handling YCbCr-4:2:2 with 8-bit or 10-bit depth. For 8-bit it's a simple pass-through, for 10-bit it depacks the stream in the AV_PIX_FMT_YUV422P10 pixel format.
