Dear ffmpeg support
I'm Oishi from KNB.
I'm trying to combine mxf file, wav file, and image files using ffmpeg.
I'm using the Windows command prompt.
Is it possible to use the codec mpeg2Video in a Windows environment?
Do I need to install anything additional to use it?
I'll post the code I'm currently creating as an attachment.
I would like to meet the following conditions.
Please let me know if there is anything I can do
・Video
Format:Mpeg Video
GOP:15
Bitrate:50M
・Audio
Format:PCM
Number of channel:8(channel 3 to 8 are silent, 1channel is stored in
8stream)
Sample rate:48KHz
Bit depth:24bit
I hope I can hear from you soon
Best regards
