what mp4 file encoding is supported in watching directly inside the browser kinesis video console

Question

I'm uploading an MP4 to a kinesis video stream using the example:

```
gst-launch-1.0 -v  filesrc location="/data/videos/20220217110106-usb-046d_0825_1A0D6A40-video-index0.mp4" ! qtdemux name=demux ! queue ! h264parse !  video/x-h264,stream-format=avc,alignment=au ! kvssink name=sink stream-name="audio-video-file" access-key="YourAccessKeyId" secret-key="YourSecretAccessKey" streaming-type=offline demux. ! queue ! aacparse ! sink.
```

but i can not play the file in the kinesis video console "Media Playback"

If i live stream from my usb camera like:

```
gst-launch-1.0 v4l2src io-mode=2 do-timestamp=TRUE device=/dev/video0 ! video/x-raw ! queue ! videoconvert ! video/x-raw ! x264enc bframes=0 key-int-max=10 bitrate=500 ! video/x-h264,stream-format=avc,alignment=au,profile=baseline ! queue ! kvssink name=sink stream-name="audio-video-file" access-key="YourAccessKeyId" secret-key="YourSecretAccessKey"  stream-name="audio-video-file"
```
it does play... just wondering is the following file supported :

```

Thank you, it turned out that the way the mp4 file was saved needed some changes:
https://forums.developer.nvidia.com/t/nvv4l2h264enc-output-is-different-from-x264enc/203981

so when i used the gpu version of x264 encoding i needed to add

nvv4l2h264enc maxperf-enable=1 **disable-cabac=true idrinterval=60**

that made the file visible in the chrome browser (firefox was able to play the kinesis stream without that as well... )

Hello,

Looking at the video that you are using, I believe this should work with KVS, however to investigate further, can you please try adding the Region in the command[[1]], and also enable debug mode[[2]] while running the command? Please let me the result of the debug command.

Also, please try to open a case with KVS team and share with them your use case as well as the test video so they can try replicate the issue from their side.
