9Rush Frozen Video - "Operation not permitted"

stevebow · Post by **stevebow** » Sat Jun 13, 2020 09:32

Since yesterday here in Sydney, whenever I change to 9Rush, while the audio is ok, the video is frozen on a frame of the previous channel. Power off/on did not help, and 9Rush is the only channel this happens on. Needless to say, I haven't touched any settings and this just started happening out of the blue. T4 firmware is 20191106.

Maybe 9 Engineering have messed with something, but 9Rush is fine on my TV, so the problem appears to be localised to the T4.

Looking at the serial o/p, I noticed the following diffs between a good "regular" channel and 9Rush:

Regular:

Code: Select all

[...]
{550}<  1359.841> [eDVBVideo0] VIDEO_PLAY ok
[...]
{550}<  1359.967> [eDVBChannel] getDemux cap=00
{550}<  1359.983> [eDVBVideo0] VIDEO_GET_EVENT SIZE_CHANGED 720x576 aspect 3
{550}<  1359.999> [eDVBVideo0] VIDEO_GET_EVENT FRAME_RATE_CHANGED 25000 fps
{550}<  1359.999> [eDVBVideo0] VIDEO_GET_EVENT PROGRESSIVE_CHANGED 0
{550}<  1360.000> [eDVBServicePMTHandler] PATready
[...]

9Rush:

Code: Select all

[...]
{550}<  1376.260> [eDVBVideo0] VIDEO_PLAY failed: Operation not permitted
[...]
{550}<  1376.368> [eDVBChannel] getDemux cap=00
{550}<  1376.380> [eDVBServicePMTHandler] PATready
[...]

The next step is to reflash the T4, but I'm not sure that would help as all the other channels are ok. Has anyone else noticed this with 9Rush, or any ideas why "Operation not permitted"?

I've attached the full logs. Incidentally, each time I change channels the serial o/p is always dropping characters around lines30-40. I've padded the missing chars for the diff to work properly.

Same here last night in Mel on a T2 - re-booted and no change. Get the same happening as you, image frozen on screen from last channel but 9Rush audio playing. Switched over the the TV tuner and it was working OK.

Looks like someone at 9 stuffed up and configured an invalid PCR in the mux stream. The decoder can't proceed without a valid clock.

It seems somebody has unstuffed something at 9, 9Rush is working again.
