628,Frame copy concealment is not working for h.264,hardiksharma,michael,"I am trying to decode from .264 to yuv format.
I dropped slices (one by one) in h.264 file format and then decoded the .264 to yuv format. During decoding, decoder is dropping the respective frame if I drop the slice which contain whole frame. This type of scenario only comes with B frame till now where my frame size is lesser then slice size. 

Command line to decode- ffmpeg -b:v 512k -r 30 -i error_$sliceno.264 -b:v 512k -x264opts sar=352:288 -r 30 -y decode_$sliceno.yuv
