Rockchip: Often video hangs or stutters on particular HEVC broadcasts

[tmn505]

Hi.
When using the plugin with particular Polish DVB-T2 HEVC broadcasts the video often stutters or hangs (audio plays without issues). It causes these messages in kernel log:

Here's a link to the sample recording: https://mega.nz/file/pFpkDBZR#q3nyGl6z0lWVqGUAk-_07tnPBfeN8iiTYa_bu14Jy08

The other DVB-T2 HEVC broadcasts play fine, which are Polish public television and Czech multiplexes.

My system is Asus CS10 (RK3288) with installed LibreELEC 12.0 (kernel 6.6.x, ffmpeg 6.0.1) built with VDRSternELEC and source of signal is streamdev-client plugin.

PS
Do You use the plugin with Rockchip devices? If yes, which SoC, what distro are You using with what modifications? Thanks.

Regards

Your sample plays fine on an rk3399 (Rockpro64 board). Sorry, I have no 32-bit board with running linux. So I can't test it with 32-bit. Can you test this on another board with an 64-bit linux?

I'am afraid that there are a memory issue. => Page fault at 0x05e15000 of type read

Unfortunately I don't have 64-bit ARM system supported by Your plugin.

That could be the problem, the device gets pretty warm and CPU temp goes close to 70 C. Will check on my other RK3288 device (Asus C100) if it gets the same issue.
