Comment (by markfilipak):
I've tried several large M2TS files. These symptoms appear to be hard.
Computer:
Windows 10 1803.
Physical memory: 32 GB.
Disk: 1 TB, SS RAID-0, 562 GiB free.
Key:
[PE] is Windows Sysinternals, Process Explorer
[MPV] is MPV player (Windows)
ffmpeg -report -ss 0:00 -analyzeduration 5000000000 -probesize 5000000000
-i "I:\BDMV\STREAM\00001.m2ts" -filter_complex
"telecine=pattern=5,split[A][B],[A]select='not(eq(mod((n+1)\,5)\,3))'[C],[B]select='eq(mod((n+1)\,5)\,3)',pp=linblenddeint[D],[C][D]interleave"
-map 0 -c:v libx264 -crf 20 -codec:a copy -codec:s copy
"C:\AVOut\00001.3.MKV"
Processing Events:
[PE] Initial memory use is approx. 650 MiB.
[PE] Memory usage climbs from there.
- Private Bytes: Rises steadily to 124.1 GiB (Note 1).
- Working Set: Stabilizes in 23 to 25 GiB range, up-down-up-down (Note 2).
[PE] ffmpeg.exe runs 33 threads.
[ffmpeg] Displays continuous series of "Starting new cluster due to
timestamp" when [PE] memory usage reaches 8.8 GiB.
[ffmpeg] Displays "Error while filtering: Cannot allocate memory" when
[PE] Private Bytes reaches 124.1 GiB.
(Note 1) Since these allocations exceed the amount of physical memory, and
since I saw a process named "Memory Compression" open-close-open-close, I
assume that Private Bytes means virtual memory.
(Note 2) I assume Working Set is physical memory.
Playback of 00001.3.MKV:
[MPV] Total time starts at zero (instead of 2:51:57) and rises by about
2x(Running time).
[MPV] When Running time reaches about 3:30, video freezes while audio
continues.
[MPV] Total time stops rising when it reaches 8:24.
[MPV] When Running time reaches 8:24, Total time begins rising again,
keeping 1 second ahead of Running time.
[MPV} Abruptly closes, but I didn't catch the Running time when it closed
-- it was greater than 10:00.
