Memory usage with bmdplay specifically

[danpisarski]

I know there is a longish previous thread under "Memory Usage", but also noticed the libav / nut branch that thread refers to appears to no longer be in the repo.

I am seeing bmdplay grow in memory usage - playing a 720P stream over the course of about an hour, it grows to around 1.4 GB.

I know in the previous thread there was some conclusion that the nut container format was the culprit, but also the conclusion that you could not change that option in bmdplay (vs bmdcapture) since in that scenario, you are intputing the format into bmdplay and you can't just randomly try an alternate format.

SO, I wanted to ask: was there every a conclusion on bmdplay? were the changes in the nut / libav branch included in master eventually? anything to try or data I can send you with bmdplay and high memory usage?

Thanks!

If it is at all helpful, the ballooning seems to happen suddenly: that is, bmdplay will run for ~ 20 or 30 minutes at say 680 MB memory used (according to top), then in the next 5 minutes grow to 1.2 GB and hover there - I think that pattern repeats until its doubled and run out of memory.

Maybe that gives you some insight into where the balloon may occur.

Can you confirm you still have memory issues with the latest decklink drivers?

I just pushed another update to bmdplay, you might test it as well. To my knowledge (and the 100+ deploys my customers have) bmdplay works correctly.

I update the experimental nut branch to cope with the wacky memory-usage-over-days issue as well.

Thank you both, will definitely try it with latest blackmagic drivers and your latest code, and report on results.

I have the same problem with BMDPLAY. I'm using the latest bmdtools, libav (both from Nov.01.2014) and Desktop Video 10.2.3 drivers for Linux. I tried nut, avi and asf and memory still is increasing. But with nut it is increasing a way faster. If anyone have solved this, please could you post your driver version. I'm on Ubuntu 12.04. Would be great to know if this problem is related to driver, so we can contact blackmagic support.

I plan to make bmdplay a stand alone player soon stay tuned :) On 4 Nov 2014 09:22, "felix303" [email protected] wrote:

Hi, I am having a problem compiling bmdtools under ubuntu 12.04. The error is:- bmdcapture.cpp:36:28: fatal error: libavutil/time.h: No such file or directory

If I look at the files which libavtools-dev package installs on 12.04, time.h does not seem to be there. Indeed a find across the filesystem only finds the system related time.h files, so I don't think I am missing a location where the libav package could have put them. Ubuntu 14.04 seems to have a time.h but I cannot use 14.04 rather than 12.04 due to problems with by graphics card driver in 14.04.

The lines below are where the issue is, and I'm not sure how to proceed.

#include "libavformat/avformat.h" #include "libavutil/time.h"

Regards, Andrew Stringer.

Install the updated libav using the motumedia ppa.

Thanks, I have had a look at the ppa, but it seems that ubuntu 12.04 is not listed, but later versions are. I am limited to 12.04 because the video driver for the embedded card in the 1u server has been withdrawn from from 14.04 for perverse reasons and so I can only use the framebuffer. Without any acceleration, it is too slow to use for anything, let alone any video playback. Your tools compile just fine on my desktop with fedora which installs the libav as part of ffmpeg. Something compiles on fedora 1st time, but not ubuntu! That's a first... :-}
