<p class="MsoNormal">Hi,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I'm encoding a YUV video to H.264 using nvh264enc. When I use the first pipeline blow, the encoding works but I cannot play the MP4 file in VLC 3.0.8 (Ubuntu 18.04) but only using the Videos application of Ubuntu. However, when I add a
h264parse element between nvh264enc and filesink, as in the second pipeline, I can play the video without a problem in VLC. Any ideas why this is happening? I don't really understand why I need the parser element h264parse after the encoder<o:p></o:p></p>
