Remnant threads in media player after playback

[koki]

A couple of threads in the MediaPlayer keep consuming CPU after the playback of a M4V video file is finished. It seems to happen with all the M4V files that I have here, but not with video files in other formats.

I can provide a sample file if needed. For now I am attaching a screenshot that shows the threads in question, and a BT from the KDL debugger.

(Feel free to change component if necessary.)

probably a bug in the mp4 reader, reassigning

Replying to marcusoverhagen:

From the bt attachment it looks like the mp4 reader is not detecting EOF on that file so is continuing to read chunks.

I will debug further.

I am having trouble reproducing this.

I am using the duetto_8-9.m4v file you sent me before.

Is there anything else you can tell me about what is happening?

@dlmcpaul

Thanks for looking into this. :) I am not doing anything unusual during playback; in fact, I can reproduce this 100% of the time by playing the above-mentioned file right after booting the system, without starting any other apps.

For what may be worth, here is the hardware this is happening on:

Acer Aspire One netbook Atom CPU (N270, single-core w/hyperthreading running @ 1.6G) Intel 945GSE Express chipset Intel 82801GBM (ICH7M) I/O controller

I am using the Haiku HDA native driver (OSS not installed), which otherwise seems to be working fine for the most part. Haiku revision is 29843, and this is gcc2 build.

There are what look like HDA-related entries towards the end of the syslog; if this is something that may help, I could attach the syslog if you want.

Ok I will try to load the current build on my Eee PC (similar specs to above)

I might send you a debug mp4_reader as well later.

There is no mp4_reader anymore, ffmpeg takes care of this now. Closing.
