Does this also happen if you only use ffplay?
$ ffplay -f avfoundation -framerate 25 -pixel_format uyvy422 -i "0"
Please test current FFmpeg git head.

Hello,
Do you know if ffmpeg can encode klv data from a csv file and inject it
into an existing mpeg ts file? (Or any other appropiate container?)
Thank you,
Best Regards,
Andrew

Thanks for the replies. I guess I'll just have to stream it in h.264. That
seems to work fine.

Carl and I both gave full example commands.

I don't know if the issue is the file reading or the demuxer,
feel free to test a few different file types like avi, asf, mov,
mpegts.

It is possible to give full command with example to i better to understand
,Bcz i new in ffmpeg.it would be great help from your side.

No, unless someone step in with request to sponsor developement.

Lowering surfaces in GTX 1070 Ti to 2 only reduces memory to 129MB, so it
is still not the same as GTX 1050 Ti. Also, 2 surfaces are not enough for
correct decoding, decoding has errors.
Using nvdec with command:
ffmpeg -hwaccel nvdec -f mpegts -i

Thanks Gyan, we'll give mp4box a shot.

Hello there,
On the system using more VRAM, can you lower the -surfaces value from 8 to
~6?
Also, in place of h264_cuvid, use nvdec instead.
Example:
ffmpeg -c:v nvdec -surfaces 8 -f mpegts -i
https://samples.ffmpeg.org/V-codecs/h264/HD-h264.ts -vcodec libx264 -preset
veryfast -crf 23 -c:a copy
In order to dynamically encode file and upload them to a server, I output
ffmpeg to pipe:1 and use curl to post the result to a file.
The problem is when I use MediaInfo to check the file, it appears as 'Open /
Incomplete' and the duration is no longer available. Is there a solution to
make th
I am using h264_cuvid in some systems. GTX10xx cards have the power to
decode many full hd streams concurrently.
I have found that memory allocated in the GPU differs between GTX 1050 Ti
and GTX 1070 Ti. With the same command, same settings, ffmpeg allocates
only 87MB in GTX 1050 Ti while it alloca
