FFAStrans forum

Hello everyone,

I don't get audio / sound after encoding a file to mpeg2. The video works fine but the audio is not inside. Doesn't matter wich original file it is. What to do to create MPEG 2 output?

I use the PCM_s16le + Channelmapper and a/v/ media.

In the optionbar i use the -ac 2 regarding the audio aac extract.

I need to create an high end full Mpeg2 output but can't fix it with FFAStrans

Any help is welcome!

Greetings Robin

Hi Robin, thank you for using FFAStrans and welcome to the forum!

You need to give us some more details on what exactly you're trying to accomplish and by what means. Are you using the "Custom FFmpeg"-encoder node? And if so, does your commands work outside FFAStrans with just the command line version of ffmpeg?

The easiest thing is to export your workflow and post it here

Thanks for the quick answer. Yes I try to use the Custom FFmpeg to create an ordinary MPEG2 export file. If i use the MP4 export it will work fine but with the custom ffmpeg exports settings the audio will not be there in the export video clip.
Workflow included!

PS: I tried already some audio parameter options but still the same error! No Sound at all!

Thanks again,

Best regards,
Robin

Hi, the reason is that the mpg container implemented in ffmpeg is not directly compatible with pcm audio. Your command is therefore invalid and will also fail when using ffmpeg.exe from command prompt. Therefor I must kindly ask you to read this topic:

Try using mp2 audio encoder and 384k bitrate to get good quality audio when using .mpg containter.

Thanks for that, i wil give it a try!
