Recording FFMPEG channel

General
1

Hello,

Congratulations on the CasparCG!!!. But it’s frustrating about Caspar’s documentation, I’m sorry. But a lot of versions a lot of evidence to get something.

I need to get clear with the recording in v2.3. I’m running 3 channels, 2 players in HD and the 3 input Decklink input in PAL only for NDI and recording. NDI its perfect. But i would need to record the PAL input, but I can’t find the right codec for an MPEG2 IBP MP@ML, close GOP, and PCM 16 audio.

For example if I use:

ADD 3 FILE "NVCE1.mp4"  -c:v mpeg2video -pix_fmt yuv422p -s 720x576 -aspect 16:9  -c:a pcm_s16le -f dvd

For PAL DVCAM dv the same:

ADD 3 FILE "test1.avi" -codec:v dvvideo -vf scale=720:576

In the case of H264 with NVENC it works wonderfully:
H264

How can I control the recording parameters for this version of CasparCg?

Thanks for your help

Try following command.

ADD 1 FILE "NVCE31.avi"  -codec:v mpeg2video -codec:a pcm_s16le -b:v 10M -filter:v format=pix_fmts=yuv422p,scale=720x576,fps=25,setdar=16/9 -filter:a pan=stereo|c0=c0|c1=c1

Ok!! Great

Work Ok, but if the name is xxx.mpg not work!!! :frowning:

It would be great to have a list of broadcast recording formats.

In Spain the most poupular in formts in broadcast is:
¿How encoder correctly for this format?

VÍDEO ALTA DEFINICIÓN (HD)
-Format SONY XDCAM HD 422 @ 50 Mbps (wrapper MXF OP1A)
-Códec: MPEG HD422 for XDCAM HD
-Resolución1080/50i

-Rate control: CBR (Constant Bit Rate)
-Level: 422P@HL
-Resolución: 8 bits, 48 Khz 24 Bits

Thank you for your work, it’s impressive!!!
