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 ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org

Re: [FFmpeg-user] h.265 streaming to youtube

Thanks for the replies. I guess I'll just have to stream it in h.264. That seems to work fine. On Sat, Sep 8, 2018 at 6:10 PM, DopeLabs wrote: > it would also help if youtube actually supported hevc ingestion... > > https://support.google.com/youtube/answer/2853702?hl=en > > > > > On Sep 8,

Re: [FFmpeg-user] When using h264_cuvid, memory allocation differs between different nvidia GPUs

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

Re: [FFmpeg-user] When using h264_cuvid, memory allocation differs between different nvidia GPUs

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

[FFmpeg-user] Piping FFMPEG out makes loosing file duration

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

[FFmpeg-user] When using h264_cuvid, memory allocation differs between different nvidia GPUs

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
