Mux problem

[darkblue99]

Now, I'm trying your encoder SDK(trial verion) to check whether it can be used for our product.
I want to encode Audio and Video with your MPEG4 compressor and then both stream go forward into your Mux to be Mpeg2TS stream.
So, I set your mux property as "Transport Stream" and I didn't touch anything else.
I saved TS as *.mp4 file.
At that time, I found your mux makes very big file.
It may be 7~8 MBytes per sec.

Please let me know why it happened and how to solve.

Hi,

"7~8 MBytes per sec. " perhaps you talk about MBites?

please check the bitrate settings on the encoder's property page. If the bitrate is near 7~8 MBites, so the bitrate of multiplexed stream is also high. Also check the "Use Padding" flag on the Transport stream property. This flag should be "NO".

ps
Perhaps you want to make MP4 file format, in this case you should use MP4 Multiplexer, but not the TS Multiplexer.

Hi
Thank you for very fast reply
I checked "NO", but nothing is changed.
I think there are some mistakes.
I gave up to solve , and I decided to follow your recommendation that using mp4 mux is better than using TS mux for me.

And I have another question.
I want to transmit file during saving currently. (streaming)
For that I need muxed stream.
So, I used sample grabber next to mux.
But sample grabber could not be connected with your mp4 mux.

So, I connected my custom file writer filter with your mp4 mux.
custom filter support concurrent read/write operation.
But saved file didn't render.
my custom filter operation is simple.
Stream from your mp4 mux is saved sequentially on file.
No modification or addition is.
I think it should be playable.
But I can't play it.
So, I wonder whether some addition is needed such as mp4 header.


I know your network renderer filter. But I should use particular network protocol.
So, I'm considering with your customization service.
But before that, I want to know whether my approach is correct or not.

That means, I want to know the method to read the file during saving on file writer. Do I have make custom file writer?

Please let me know to solve the problem.
