AM62A7-Q1: Unable to get a working HLS stream using v4l2h264enc and hlssink2 using gstreamer

Part Number: AM62A7-Q1

Tool/software:

Hello,

I am trying to generate a HLS stream using the following pipeline:

gst-launch-1.0 -v videotestsrc is-live=true ! \
    v4l2h264enc extra-controls="enc,prepend_sps_and_pps_to_idr=1,video_gop_size=5,frame_level_rate_control_enable=1,video_bitrate_mode=0,vbv_buffer_size=3000,video_bitrate=6000000" ! \
    h264parse ! \
    hlssink2 \
        location=/var/www/html/segment%04d.ts \
        playlist-location=/var/www/html/playlist.m3u8

On AM62A, this outputs the first segment, and then stalls.

When I try something similar on my x86 linux machine using the following pipeline

gst-launch-1.0 videotestsrc is-live=true ! clockoverlay ! x264enc ! h264parse ! hlssink2

this works fine. I believe hlssink2 tries to make the encoder generate a key frame, and I'm not sure whether the wave5 encoder supports this.

Any idea how to solve this?

Hi Bas,

I am checking with the codec IP team on this issue. I will keep you posted as soon as I get to hear back.

I found the problem. hlssink2 uses the mpegtsmux and giostreamsink elements internally. My build added the hlssink2 element, but did not add the elements it builds upon (and there were no dependencies that added these).

Once those extra elements were added, things worked as expected.

Sorry about that.
