TImestamps in byte stream format input

[Treesa]

Hi,

I have sevral doubts regarding byte stream format and nal alignment.

Does one h264 decoder can accept nal alignemnt?

I have my own h264 decoder plugin.

Should I give only au alignment for its sink cap or giving both au and nal alignemnt caps is fine?

Hi,

I use stream-format=byte-stream,alignment=au for streaming and

stream-format=avc, alignment=au for recording. The recordings work with vlc, MediaPlayer etc.

streaming works with vlc as client.

Is it okay to have nal alignemnt input for decoder?

If yes what all things do we need to consider ? ( eg: time stamp)

Hi, timestamps are a feature of the muxer and not the encoder so they shouldn’t be affected. I would suggest you just try it out. I don’t have any files with NAL alignment so I can’t help you
