[Bug 50733] New: MUSICUS!: ending videos play are extremely choppy
https://bugs.winehq.org/show_bug.cgi?id=50733 Bug ID: 50733 Summary: MUSICUS!: ending videos play are extremely choppy Product: Wine Version: 6.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winegstreamer Assignee: wine-bugs(a)winehq.org Reporter: pernegger(a)gmail.com Distribution: --- When testing if 6.3 fixed #50686 I noticed another performance issue / regression: MUSICUS!'s MPEG1 ending videos are extremely choppy in 6.3. They're not very dynamic in the first place, so it's hard to tell what's wrong, but the audio (ending song) is fine, and the video (lyrics) are more or less in sync, so I'd say lots of frames are getting dropped, but I couldn't swear the whole thing isn't running a tad slow, too. 6.0 is *much* better. If I open the video in VLC directly, it is a bit smoother still, but without a direct comparison I wouldn't have noticed. This is on a Ryzen 7 3900X [Ubuntu 18.04.5]. (Then I remembered that I had this issue on my "laptop", too. That's a Surface Go 2 [Ubuntu 20.04], currently. Only it was *much* worse, totally unwatchable, we're talking a new frame every other second, maybe. I chalked it up to the machine being too slow, but maybe not. It's not just MUSICUS!, either, I retrospect one or two other (older) visual novels showed similar symptoms -- I just assumed the videos were crap at the time. Note that this bug is strictly about MUSICUS!, when that test case is fixed, I'll happily go back and test the other stuff, the tangent is just meant to illustrate that hardware performance may play a role in how noticeable it is.) [#50239 has slightly different symptoms, and most importantly, I'm using MUSICUS!'s 64-bit exe.] The regular terminal output has nothing, please advise on how to get suitable debug logs. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Of course, there you go. Sorry for spamming the server, I should've asked whether you really wanted all that.
Nah, I probably would have said yes regardless. I just ended up seeing weird lags in the log that made me suspect that terminal buffering or something was interfering with any useful information. Usually I do debug with GST_DEBUG=6, even for latency issues, since the relevant bottlenecks are still pretty evident. The video frame timings are very weird, but I can't tell if that's inherent to the file format. Can you please attach a log with GST_DEBUG=5 using `gst-play-1.0` to play the video? It should be at a path like base/movie/ed_c.mpg. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
https://bugs.winehq.org/show_bug.cgi?id=50733 --- Comment #9 from Zebediah Figura <z.figura12(a)gmail.com> --- Actually, maybe never mind, I think the problem is we're dropping most of the frames due to QoS (and I misread the log and thought we weren't doing that, but we definitely are). My guess is that 9c138562fe broke this (since I'm not sure what else could have), because now we're not sending QoS events serialized with samples anymore. I don't like that explanation, though. GStreamer should be able to handle that. Could you possibly attach a log of 6.0, with the same channels (and GST_DEBUG=5 is enough)? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

As before, playback wasn't a 100 % right, either, but nothing you'd notice if you didn't open the file in a video player to compare directly. As if frame times were slightly skewed, the pans are a tad mushier, too. 6.0 is alright (but it used to be flawless, even on much slower boxes). I also tried playing it in gst-play-1.0, that looks flawless, too. There's a log if do you want it after all, but I'd have to upload it in two parts. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=50733 --- Comment #11 from Zebediah Figura <z.figura12(a)gmail.com> --- So 6.0 is dropping about as many frames, which makes it unfortunately difficult to tell what's going wrong. Still, from examination, I've managed to find some serious issues with our QoS management, and I've submitted some fixes, committed as <https://source.winehq.org/git/wine.git/commitdiff/d99912aa65d63973af64f13065...>.

https://bugs.winehq.org/show_bug.cgi?id=50733 --- Comment #14 from castaneai <castaneai(a)castaneai.net> --- Hi. I found a similar problem. I have attached a minimal application that reproduces this problem. This application uses DirectShow's RenderFile API to play the MPEG file in the first argument. https://bugs.winehq.org/attachment.cgi?id=69597 It can be reproduced by unzipping it and running the following command wine mpegplaytest.exe sample_640x360.mpeg It is terribly slow in Wine 6.3. Wine 6.0 is slightly better, but slower than gst-play. In addition, I measured the processing time in the pipeline. The results show that mpegvparse0 seems to slow down the whole process. https://bugs.winehq.org/attachment.cgi?id=69598 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

I looked into this issue further. I got the current latest git master (23ffd0a7986421958c23cffce138afa389209920) and output the report of perform_qos.
The attached log shows that jitter is over 400ms regularly.
https://bugs.winehq.org/attachment.cgi?id=69625
The problem appears to be caused by the DirectShow's clock.
The jitter is negative, which means that the samples are arriving early (i.e. in time). mpegpsdemux clips seeks (including seeks to the start of the stream) to a fixed segment that spans from the PTS of the first sample to the last, and both may be nonzero. In the case of MUSICUS!, the first PTS is about 0.39294. We incorrectly use the buffer PTS to report QoS events when we should be using the running time, so mpegpsdemux perpetually thinks that the last sample to arrive was stamped later than the one it is currently processing. I was able to reproduce a similar problem with an MPEG-1 system file, though I didn't test with earlier Wine. My guess is that the bug was introduced by a3e7cfd4d7, and should be fixed by <https://source.winehq.org/patches/data/201821>. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Subjectively: still not perfectly smooth, slight choppiness in the audio now & then, too -- but I'd say it's back at 6.0 levels, so, serviceable.
