As usual, after getting a season I run a series of scripts that invoke various programs to check that I've got a full season and the downloads are actually good. This time round I noticed audio inconsistencies with flix are were longer than usual, so I verified things manually, and found that audio does get chopped at the end.

While preparing the log files, I noticed a massive disparity in the final file size between 1.0.9.1 and 1.0.9.3: an episode downloaded with .1 was 2442999901 bytes long while the same episode downloaded with 1.0.9.3 was merely 1541053674 bytes long, so I dug even deeper and found:

with .9.1:-

I haven't checked if A suffers from the same problem yet.

As for the audio, the tail of the audio track doesn't seem to get written on occasion with 1.0.9.3.

Dont have any logs for it but i also noticed the differences (file size/bit rates)
grabbed the wrong audio track for a show so re-downloaded it and got way different bit rates.
 
Having looked more closely at the MP4 box decomposition, I noticed that in the truncated (1.0.9.3) version the second entry in the sample-to-chunk (stsc) box has the first chunk number set to chunk #1248, whereas the 1.0.9.1 has the first chunk # at 1252 and the chunk offset box (stco) is 4 entries shorter in .3, could be source of lip-sync issues described in https://forum.redfox.bz/threads/htt...ds-anystream-beta-1-0-9-3-disney-80536.80645/ if the MP4 players there properly rely on box structures instead of just ignoring them (a la pc players, I suspect)...
 
Hi,
does anyone know if this bug is still present on 1.1.1.0?
I'm still on 1.0.9.0 and am hesitant to upgrade.

So going back to what I said in #7, it looks like the bugs (both of them) are gone, if the truncation did happen (and I have a low degree of confidence that it might have) it's so rare that is fixable by re-downloading
