Deposit > Upload: misleading/inconsistent percentages in Files tab during transcoding

[costaflavio]

Expected behavior

The percentage in the progress bar to give a reasonable indication of the advancement of the transcoding

Actual behavior

The percentage in the progress bar does not give a meaningful/useful indication of the advancement of the transcoding, see for example:

The transcoding progress bar shows 33%, while all the file subformats are at least at 61% or completed.

The progress bar percentage is not very usefull since in fact the transconding finishes after the 33% is displayed in a fraction of the time it took from the start to 33%.

Although server load may slow down these missing subformat transcoding, it would be reasonable to see a progress bar showing the average between the progress of each subformat:

• 73
• 61
• 100
• 100
• 93

average: 85.4%
Perhaps(?) it makes sense to count a final step for the transcoding, which reverts the progress bar back, let's say ~10% (?) i.e. 8.54%: so 85.4 - 8.54 = ~77%

77% (or more) would be much more realistic than 33%

Information about the Issue

Steps to reproduce the behavior

1. Open the Files tab during the transcoding of a relatively big file (at least few hundreds MB) and observe the percentages both for the subformats and the video progress bar

Do we know why this issue appears? @egabancho @drjova

We are not counting the individual file percentages to calculate the total transcoding percentage, in fact it represents the number of files that are done already.

It might be also a bit misleading as, sometimes, we are sending more tasks to the queue than the slaves that will finally be generated.

I would keep this open because, IMHO, we should review the way the UI presents this percentage and probably calculate the overall process better.

As it is today 28.6.17 I am not sure that the percentage represents the number of files done already, see

The new transcoding software will have a different way to handle transcoding progress.
