VLC on Hololens

[zkuang]

Hi all,
I met a problem on hololens. I tried to play a H264 stream on hololens, and I need to limit the delay. I set the --network-cache to around 250ms, this works. But if the network is unstable, the cache increase adaptively, and this increase the delay. So I modify the input_internal.h INPUT_PTS_DELAY_MAX to around 250000, this works on a PC win10 system (wifi connected). When I try to deploy the same app on Hololens (with --avcodec-hw=any), the log shows some "more than 5 seconds of late video -> dropping frame (computer too slow ?)" every 10 to 20 seconds. With cache increase to around 800ms, the streams plays pretty well. I guess I would still see the same log every now and then if this is a hardware performance issue, but I seldom see this happen.
My quest is how do I be sure that this is a hardware performance issue or something else? If it's something else, what is probably the reason?

[zkuang]

The weird part is, if I decrease the frame rate to 10 - 20 per second, the video just can't play with logs all about dropping frames more than 5s late. That looks more like a buffering issue than a performance issue, right? But I don't know what would be related, any idea?

[Jean-Baptiste Kempf]

Can you share your logs, by any chance?

[zkuang]

sure, here is the log for playing 60fps video, I truncated some noise after seeing the laggy pictures (it stops about 5-6 seconds, and I see the dropping frame log after that).

I added some logs, and I see avcodec_receive_frame returns error continuously, some the late packet start is not updated, and then I started to see avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?), the problem is these should be valid packets, why are they not decoded correctly?
