Comment (by dprestegard):
Here's a sample command:
ffmpeg -report -loglevel debug -y -i
"https://s3.amazonaws.com/download.opencontent.netflix.com/Meridian
/MER_SHR_C_EN-XX_US-NR_51_LTRT_UHD_20160913_OV/MER_SHR_C_EN-XX_US-
NR_51_LTRT_UHD_20160913_OV/MER_SHR_C_EN-XX_US-
NR_51_LTRT_UHD_20160913_OV_01.mxf" -pix_fmt yuv420p10 -c:v libx265
-threads 1 -preset veryslow -crf 12 test_01.mp4
This reads a very large (715 GB) j2k mxf file from one of Netflix's public
S3 buckets and encodes it into HEVC. I'm running this now and expect it to
time out in the next few hours. I'll provide the full debug report from
that.
Probing the source reveals the following:
Duration: 00:11:58.93, start: 0.000000, bitrate: 8548764 kb/s
Stream #0:0, 1, 1001/60000: Video: jpeg2000, 1 reference frame,
rgb48le(12 bpc, progressive), 3840x2160, 0/1, lossless, SAR 1:1 DAR 16:9,
59.94 tbr, 59.94 tbn, 59.94 tbc
Metadata:
file_package_umid:
0x060A2B340101010501010F2013000000FE44076823AB4CAC8F059C5EDECED827
file_package_name: File Package: PROTOTYPE SMPTE ST 422 / ST 2067-5
frame wrapping of JPEG 2000 codestreams with HDR metadata
track_name : PHDR Image Track
So, we should get a file that's 00:11:58.93 in duration.
