Would you try latest test build from following link?
.ts hw+ playback is improved in this test build but I'm not sure your issue is fixed because this issue looks like happening only on MediaTek platforms and I do not have device having MediaTek playform.
(Please note that hw playback is not changed though)
BTW, DVB subtitle positioning issue is also fixed.
Feedback will be appreacited !
Yes, I've tried hw+ decoder, below are results:
1) The original TS file (HBO_HD recording)
SW decoder only. Trying to switch to HW or HW+ decoder falls back to SW with error message "Cannot play this video with H/W(+) decoder".
2) TS file in which the DVB subtitle track and the Czech audio track were removed (repacked by DVBViewer-TSPlayer)
HW+ decoder is functional, but playback is sluggish on my Acer Iconia Tab A1-810 (similar performance as SW decoder playback)
HW decoder cannot play this video.
3) MKV file created from the original TS file using mkvmerge
HW decoder is functional, perfect smooth playback
HW+ decoder cannot play this video
I will send you a link to all three files to the specified email.
Thank you in advance!
