concealing 8160 DC, 8160 AC, 8160 MV errors in frame error in ffmpeg
18 mars 2019, par TaliaI have an mp4 video and I want to convert it to yuv. This video has some errors inside. I need to convert it to yuv because the target is getting PSNR between the distorted yuv and the original yuv.
I am using FFmpeg for this purpose. I get several of the consecutive following error :
[h264 @ 0x1c0ce00] concealing 8160 DC, 8160 AC, 8160 MV errors in P frame
[h264 @ 0x1bce920] concealing 8160 DC, 8160 AC, 8160 MV errors in P frame
[h264 @ 0x1be2c80] concealing 8160 DC, 8160 AC, 8160 MV errors in P frame
frame=14964 fps= 31 q=-0.0 size=45453150kB time=00:09:58.56
bitrate=622080.0kbit[h264 @ 0x1b482a0] concealing 8160 DC, 8160 AC, 8160 MV
errors in I frame
[h264 @ 0x1be9780] concealing 8160 DC, 8160 AC, 8160 MV errors in P frame
[h264 @ 0x1b827a0] concealing 8160 DC, 8160 AC, 8160 MV errors in P frame
[h264 @ 0x1b89ee0] concealing 8160 DC, 8160 AC, 8160 MV errors in P frameThen, in the converted yuv video, these frames are the gray scenes while these frames are fine in the mp4 video. So, I am wondering why FFmpeg can’t convert them to yuv.
I am using the following command to convert mp4 to yuv :ffmpeg -i d_video.mp4 -c:v rawvideo -pix_fmt yuv420p -r 25 -s 1920x1080 -y d_yuv.yuv
could you please guide me ?
