After pause (on x265 / HEVC 10bit videos only), video freeze but audio continues (sometimes)

Hello,

Video freeze happens erratically on 10 bits encoded x265 (mkv format) files when I pause the video, then when I want to resume the audio plays, but the video stays frozen. Other formats (x265 8 bits or x264) don't have this problem.

When I want to resume , most of the time it works normally, but sometimes (seems perfectly random to me) this freeze happens.

When this occurs the following error message appears in the log

avcodec error: avcodec_send_packet critical error

Some info about my hardware : Using D3D11VA (NVIDIA GeForce GTX 1060 6GB, vendor 10de(NVIDIA), device 1c03, revision a1) for hardware decoding

I've been having this error for a long time, but decided to report only today, I think I've had this error only since the vlc 3.x line but it was working okay with vlc 2.x

Please share your logs.

Ping for logs.

I get the same behavior. If I select "Video Track -> Disable" and then "Video Track -> Track 1", it will reset and work again. Also nvidia, but 1050ti.

I am having the same issue but there are no errors or warnings written to the log. The file is being streamed on my local gigabit network. Network streaming cache is set to 2000ms. The codec is h.265 and in a .mkv wrapper. Client is a Win10 x64 i4790k 32GB ram and Nvidia 1080ti.
