H264 decode_slice_header error in the first hls ts file segment

jahwan.oh · June 8, 2022, 5:47pm

Hi,

whenever I encoded video using gstreamer (h264, hlssink) , ffprobe gives me No frame error for the first HLS segment file(.ts). and the other following ts files(segment1.ts, segment2.ts …) are OK.

[h264 @ 0x5562ddd320] decode_slice_header error
[h264 @ 0x5562ddd320] no frame!
[h264 @ 0x5562ddd320] non-existing PPS 0 referenced

ffprobe segment0.ts

How can I solve this?

Hi,
Please try nvv4l2h264enc and set insert-sps-pps=1 idrinterval=15. The setting inserts SPS/PPS in every IDR frame and sets IDR interval to a smaller value.

jahwan.oh · June 9, 2022, 8:14am

I will update the result as soon as possible by today.
Do you suggest not using omxh264 nor 265 but to use nvv4l2h264 ?

jahwan.oh · June 10, 2022, 10:29am

only changing encoder to nvv4l2h264enc from omx makes it hlssink outputing only one file segment without increasing the file segment number.

I’m still looking for the solution.

jahwan.oh · June 10, 2022, 12:12pm

it works fine after adding h264parse.
thank you!

DaneLLL · June 13, 2022, 2:44am

Hi,

Yes, we have deprecated omx plugins and please use v4l2 plugins.
