Confirmed. I get these errors as well with choppy video usually 1080 or 720. I do not have a problem in the web GUI.

I also get:
21:35:36 T:139663922677504 ERROR: Decode - avcodec_decode_video returned failure

System:
Kodi v15.2 “Isengard” on a Dell GX620
HDHR tuner. (just using one tuner for OTA)
Wired Network
no CPU issues.
TVheadend is on another GX620.

Could you try to disable hardware video decoder in kodi?

When I disable DXVA2 hardware acceleration the symptom goes away. Hardware acceleration is preferable of course, but the CPU can handle decoding just fine. So while the problem is not fixed, the symptom is!

But it's kodi issue then... Report this there..

Updated by Jaroslav Kysela almost 9 years ago

Could you try v4.1-1459-gc8810d2 ? Also, could you report your result for the hw decoder when 'use packet backlog' in the general configuration is turned on ?

Updated by Jerome Wilkins over 8 years ago

The issue still persist with latest version of tvheadend. I turned on packet backlog and I still get those errors in the log with a lot of drops and skips. I tried with mpeg2 decoding disabled and I get the same results.

OK. So this bug is in tvh 3.9+ (any version), isn't ? The backlog is only implemented for h264 for the moment. I should read the error line more carefully next time.

Updated by Jerome Wilkins over 8 years ago

I tried out the mpeg2 packet backlog version and sometimes when the video start I get green artifacts or the whole screen would be distorted, however when checking the kodi logs I dont get this error no more. ERROR: ffmpeg[7FE92AFFD700]: [mpeg2video] Invalid frame dimensions 0x0.

#11

Updated by Jaroslav Kysela over 8 years ago

Jerome Morrow: The problems are at the video start only or also when the stream continues ? As I understand correctly, do you use Intel GMA 950 graphics?

#12

Updated by B C over 8 years ago

isn't this expected as the backlog must not start on an I frame?

#13

Updated by Jerome Wilkins over 8 years ago

Yes it happens at the start of the video and as the video continues. I use intel haswell graphics.

#14

Updated by Jelly Frog over 8 years ago

Having the same issues, stuttering, skipped frames... Playing the source (http iptv) directly works flawless
See attached logs from kodi/hts
