Choose the right mux, a/v codecs

[mcsniper95]

Hi everyone,

I have a video file that I have to stream into 3 diferents formats:
- poor quality, for example: PDA
- medium quality, for wireless connection
- high quality, for ethernet connection

Could you please explain to me how to do put it together in the vlm,
I mean it will be something like this:
- MPEG2+MPEGA(TS)
- H.264+AAC (TS)
- RAW or MP4

But what are the best options for poor, medium and best quality,
How do I know wich samplerate,fps,vb,ab,height,width I have to use for each connection?
Do I have to use ffmepg, deinterlace,dump raw input.

I m really confused with all this A/V codecs, containers, formats, heights x width, fps, samplerate.

Could you help me please.

Best regards

I think you must use TS.
H264 and MPEG2 can have the same bitrate, so if you have enough CPU you should use MPEG4 or H264.
I don't think you can transmit raw video through ethernet.
To have different bitrate, the best is to change the resolution first (a PDA don't need HD), and if it's not enough you can decrease fps, or reduce the quality (vb).
The only way to know what you want is to try different combination and see the result in quality and bandwidth.

I don't know the command line options for all of this, but you can find it in the documentation.
