Mass Migration from AMS Utterly Failed.
Quick report on our (failed) attempt after 3 sleepless nights trying to migrate >3,000 videos.
The queue only holds 1,000 jobs at any time, and only processes two at most at any given time. And if anything goes wrong and you have to "retry", you're losing another 10 - 12 hours.
- .AVI and .WMV videos failed completely!
- a large percentage of .MOV videos failed.
Overall, half of the videos failed with various errors. I'll be spending time later today, opening tickets with one sample for each error type below. Error messages encountered:
- Encoding seems stucked -> abort
- aborted
- The first video sample is an end of stream
- Failed to parse input when demuxing
- Corrupted data on input when demuxing
- The first video sample is an end of stream;Output did not receive any data for Audio stream
- (No error reported, just hangs in "Processing 0%" forever)
We're using the basic TransformVideo“ with the preset „H264 multiple
bitrate 720p with constant video quality“.
