Mediainfo provides the following information
ffprobe version 4.1.3-static https://johnvansickle.com/ffmpeg/
Copyright (c) 2007-2019 the FFmpeg developers
built with gcc 6.3.0
When transcoding with CPU, adding -i /home/1.png -filter_complex
"[0:v][1:v] overlay=55:25" worked fine, but with GPU its throwing an
error msg
This is the command I tried using
ffmpeg -vsync 0 -hwaccel cuvid -c:v h264_cuvid -deint 1
-drop_second_field 1 -i 'udp://0.0.0.0:' -i /home/1.png
-fil
It seems like again I hit the wall. While one mpeg2 source works with
the mpeg2_cuvid option, the other gives me troubles.
ffmpeg -threads 1 -vsync 1 -hwaccel cuvid -c:v mpeg2_cuvid -deint 1
-drop_second_field 1 -i 'http://0.0.0.0:46007' -c:v h264_nvenc -vb
1000k -preset:v medium -c:a aac -ac 2 -a
This finally fixed it:
-hwaccel cuvid -c:v mpeg2_cuvid
Indeed, you need to specify the input type before transcoding!

Whatever further processing is done, I think that scaling down to 480

Looking more at the sample it does seem that the progressive scale and

Hi Bouke, Thanks for your prompt response.
Please don't top post.
For me the idea is to get field based interlaced streams to test some
of my implementation. Maintaining frame rate is not an issue with
me.
I tried with tinterlace too but not to my luck.

Vid looks like it's scaled up from 480 height and pillarboxed, so

It's probably been scaled as progressive which on strong chroma
will (I think) be un-mendable. Saying that the sample can be scaled
down

I tried and it seems the encoder has issues, needs -strict -2 and isn't

Hi List,
I'm a new user here and want suggestions for "best" ffmpeg syntax to

The AVCHD-SD specification is possibly something that could be used

Hi All,
I need to mux and then framerate convert a rawvideo .mov file, and a PCM 16bit

For example, a .mov file is exactly 10 seconds long, and a .wav file is also
exactly 10 seconds. The initial .mov file is a 30 frames-per-second, but after

Notice by accident and may be one off unlucky sample.
Out of curiosity I did ffmpeg -i on the second m2ts stream of a

This ate all mem (8G) and swap (4G) before oom killer killed ffmpeg.
This was git and as it didn't happen with my older installed ffmpeg

Possibly, or you didn't restrict to baseline.
You really should know what format the source video is is to do
things properly.
If say it's interlaced and stored as 422 or 411 then the default
conversion to 420 will be wrong. You would need to add interl=1 to
