omxh264enc does not send keyframes at regular intervals

[DaneLLL]

Hi piperak,
Besides, I tried to run with x264enc and the result also looks wrong. Have you also tried x264enc?
The pipeline:

Using launch string: videotestsrc is-live=true ! video/x-raw, width=800, height=600, format=(string)I420 ! x264enc ! video/x-h264, stream-format=(string)byte-stream ! h264parse config-interval=1 ! splitmuxsink location=/home/nvidia/test-%02d.avi muxer=avimux max-files=5 max-size-time=10000000000

I think for ‘max-size-time=10000000000’, the duration should be 10 second. Is my understanding correct?

Hi,

I can confirm that sending an EOS solves the zero file size issue. But, splitmuxsink does not split the files correctly anymore. In fact it does not split at all after restarting.

Moreover, if you have a pipeline with audio, you need to send an EOS to the corresponding pad also.

Have you figured out why the EOS signal does not reach splitmuxsink?

I found http://gstreamer-devel.966125.n4.nabble.com/splitmuxsink-with-rtspsrc-EOS-problem-td4680078.html

It is an issue in splitmuxsink itself and not an issue in NVIDIA omxh264enc

Hi,

I have finally figured out what is wrong with this pipeline. The EOS signals are not reaching any of the sink ports of the splitmuxsink element.
I resent the signal every time the stream is stopped. This work fine for video, but if you muxing audio as well it does not.
The file splitting issue is already registered as a bug in the gstreamer bug database.
I will not spend any more time on this issue, I will just file a bug to gstreamer and wait for a fix. Thanks for the assistance.
