78149d6657 amfenc: Retain a reference to D3D frames used as input during the encoding process 
This fixes frame corruption issue when decoder started reusing frames
while they are still in use of encoding process

Issue with frame corruption  was reproduced using:

    avconv.exe -y -hwaccel d3d11va -hwaccel_output_format d3d11 -i input.h264 -an -c:v h264_amf output.mkv

It is recommended to use -extra_hw_frames 16 option in case if hw frames
number in pool is not enough

80a4e6a46f amf: Replace writer_id option with LIBAV_AMF_WRITER_ID constant 
AMFTraceWriter is an abstraction to configure how AMF outputs its logs
for the current process and can be configured to output different levels
of trace output. If multiple LibavWriter objects are used in one process,
there will be duplication of output in av_log. Use a constant writer_id
to prevent this scenario.
