HLS TS segments generated by nvh264enc is not playing (except the first segment)

[Ugur]

I have two pipelines that creates hls video. Unfortunately when i use nvh264enc only the first ts file is playable. When i try to play the second file or the other ts segments I see a black screen.

Then i run ffprobe on the segments. For the playable segment:
Stream #0:0[0x41]: Video: h264 (High) (HDMV / 0x564D4448), yuv420p, 320x240, 30 fps, 30 tbr, 90k tbn, 60 tbc

For the failing segment:
Could not find codec parameters for stream 0 (Video: h264 (HDMV / 0x564D4448), none): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

x264enc pipeline:
gst-launch-1.5 videotestsrc is-live=true ! x264enc   ! mpegtsmux ! hlssink playlist-length=100 target-duration=5 playlist-location=x264enc.m3u8 location=x264enc%u.ts

nvh264enc pipeline:
gst-launch-1.5 videotestsrc is-live=true ! nvh264enc ! mpegtsmux ! hlssink playlist-length=100 target-duration=5 playlist-location=nvh264enc.m3u8 location=nvh264enc%u.ts

So it looks like an issue with incorrect/nonexisting meta data.

Any suggestions what how to fix it? Or what could be the cause?

Best,
Ugur

Although not using the nvenc element, I encountered a very similar problem which is documented in Bug #760980 (https://bugzilla.gnome.org/show_bug.cgi?id=760980). See also the attachments in that bug which yield the exact same result when played/ffprobed.

Perhaps the SPS/PPS is missing/malformed in the second segment?

Try to insert h264parse after nvh264enc, which can add PPS in the stream
gst-launch-1.0 videotestsrc is-live=true ! nvh264enc ! h264parse
config-interval=1 ! mpegtsmux ! hlssink playlist-length=100
target-duration=5 playlist-location=nvh264enc.m3u8 location=nvh264enc%u.ts
