I've had a long 2nd-pass job end in an error twice in a row on a certain video. The AVS script has only one command (AviSource). The x264 settings are identical to many other videos I've encoded, and those videos are all about the same length & content. I can play the source file from start to finish in media players & thru Avisynth without any errors.
Using x264.exe dated 2005-12-19 19:36, as I have for several other successful jobs.
Both attempts left an output MP4 file that was corrupted (incomplete, both ~1/10 of the expected size). I deleted the stats file and reran the 1st pass between attempts.
The MeGUI log isn't terribly informative about what's going wrong:
Next job job1-1 is a video job. encoder commandline:
"c:\program files\x264\x264.exe" --pass 1 --bitrate 2000 --stats "D:\Vid\duke-davidson-avisource.stats" --bframes 3 --b-pyramid --filter -2,-1 --subme 1 --b-rdo --weightb --trellis 1 --analyse none --me dia --threads 4 --sar 8:11 --progress --no-psnr --output NUL "D:\Vid\duke-davidson-avisource.avs"
