Re: FFAStrans hardware configuration

I have been using FFASTrans 1.0.0 with custom ffmpeg specifying h264_nvenc as codec and has been working well. With a nvidia P2000 and localized files on ssd array, I can encode 4 HD 59.94 Prores files to mp4 in realtime! Upgrading soon to a PC with 20 xeon cores and 2 nvidia P4000 cards which shou...

Re: FFAStrans hardware configuration

Not sure if OBS Studio community can help with this? Nice approach to peek to some other existing tools but unfortuantely OBS does not seem to utilize ffmpeg.exe at all. To be honest i don't think it will help a lot to peek at other tools, unless there was some tool that had a very similar approach...

As OBS Studio has support for all of that about hardware encoding.
As their source code is available on GitHub, might check how they do it?

Audio extraction - Expected number for ar:a:0 but found: Same. - v1.0.0.2

Hi! I'm trying to extract all audio tracks from MP4 file. I know that this video has 8 audio tracks with 2 channels on each. I'd like to extract them all in separate files. I've did this: https://prnt.sc/rbfdks And I always get the same error whatever I do: Expected number for ar:a:0 but found: Same...

Re: FFAStrans hardware configuration

@veks for decoding how about that? https://devblogs.nvidia.com/nvidia-ffmpeg-transcoding-guide/ What you should know about decoding on Intel/AMD/Nvidia cards is that you can of course only decode a few configurations of each codec, e.g. little britrate, certain levels etc... and much more interesti...

Re: FFAStrans hardware configuration

Well said, and I'd really like to see someone comment on this with that kind of knowledge. I was trying to find some papers about it online, but not much from 2019 and above. Mostly before 2018 when GPU was far slower and not that useable as nowadays. NVENC/CUDA chips changed a lot. We're seeing the...

Re: FFAStrans hardware configuration

Maybe the difference would be dependable on a workflow in production and for which kind of content it is being done. For example, in OTT, you need to transcode for example MPEG2 to H.264 or H.265 which Quadro GPUs transcode like nothing. You can easily stack them in servers and use them for many sim...

Re: FFAStrans hardware configuration

Thanks a lot momocampo! As for the NVIDIA CUDA GPU encoding, we're running it with built FFMpeg from GitHub that has NVIDIA CUDA support. Right now on Linux Mint (latest) with Nvidia Quadro P2000 and that works great! Inputs are 6 Full HD - HEVC channels that are being transcoded to 6 profiles. It w...

FFAStrans hardware configuration

Hi all, I have a question about what type of hardware you're running FFAStrans on and also a farm. I know that developers of FFAStrans are running it as a farm. So I'd like to know on which hardware? Do you use CPU or GPU for transcoding? Specific hardware, what CPU, what GPU, how much RAM? Do you u...
