... after seeing the logcat... any ideas as to what is causing videos to starting hanging after playing 50+ 5s videos consecutively? I looked at the memory profiler and it appears that garbage collecting of memory is happening. I tried to find where buffer files are being stored under data/data... but could not find them if they are being written to memory.
Is Geckoview buffering videos if they are being played from extSD storage? That seems to be the only reason why playing lots of short videos in a short amount of time would result in video play hanging. If it does buffer can that be turned off so that resources are not used up? Thanks!

I only included the portion where the JS auto playing each 5 sec video started to hang. By this I mean after playing a video it tries to start playing the next video but I have to intervene and press the play button for every other video because the auto play is not doing its job.. Then soon I had to intervene on every video by pressing the play button to get it to play. The nightly version (which can't be logged... right?) ... would eventually get to where even pressing the play button could not get the video to continue. Is this the logcat that you requested? The debug version actually starts to show the hang symptoms sooner after install than the nightly. Maybe after 30 videos. Whereas the nightly does not show symptoms until 90 videos. Thanks!

You can collect device logs running `adb logcat` on a terminal while the device is connected to your computer.

My use case is children viewing hundreds of 5s video clips per session. So it may be best if I can prevent the caching of video to not happen at all. If that is what's happening. I have preload turned off in the html/JS that calls each video.. <video name="video_player" id="video_player" style="display:none" controls preload="none"> <source src="mp4" type="video/mp4"/> </video> Once I watched a Google Developer announcement that talked about how they had built a video play api that was good for streaming video. It would smartly buffer video while checking the network speed and determine on the fly whether to lower the resolution so the user did not encounter pauses. Could it be the case that that technology is being used with Geckoview? If so ... is there a way to turn off the smart buffering in cases where it is clear that the video is local... i.e. no network delay? This is not my first rodeo with buffering clogging up the works. With hundreds of short video clips that all get exercised... preload="none" was the cure. If GeckoView is smart buffering the beginnings of each video ... how can I turn that off? Thanks!
