IMX8M : gstreamer give error on H264 stream

[fredericduchass]

Hello,

I try to decode an MPEG2TS stream which is encoded with h264. I use the couple h264parse + vpudec and i get many many errors at the output :

ERROR: h264bsdDecodeSeiParameters error

ERROR: h264bsdDecodeSeiParameters error

ERROR: h264bsdDecodeSeiParameters error

ERROR: h264bsdDecodeSeiParameters error

.

.

.

.

Do you know what the reason and meaning of this error ?

BR

Frederic

could you share your video and your gstreamer commands?

how about using "gplay-1.0" or "gst-launch-1.0 playbin uri=xxxx?"

I played out.ts on the PC, I found mosaic in the first one second, and then I played on the board with gplay-1.0 out.ts, and I got the same error, but I can see the video on the display successfully, so I suggest that you can test another ts file, I'm not sure if there is something wrong with your ts file, and the error message doesn't affect playing this ts file

Hello Joan,

You're right the display is not affected by this message. All seems decoded perfectly.

But this message should not be very safe.

This is another TS files with the same error :

https://wetransfer.com/downloads/0272b72f7f96205ad8271d332cf5738920190130082423/83359a9b86d9f64dbaa3...

I have many other which gives same error because it's french terrestrial TV.
