How can I create ProRes HQ video files with 5.1 SMPTE DTV audio using
ffmpeg? The input file is:
Apple FCP Uncompressed 10-bit 422 1920X1080
FPS 23.98.
The audio has 6, 24-bit integer (little endian) mono channels, plus a
stereo track, configured like this:
Mono = Left
Mono = Right
Mono = Center

Your solution to override the hard-coded limits seems promising at the
first glance. I'll try that soon and report ba

You have the Quadro P4000, which is artificially crippled to ~2 concurrent
sessions according to the documentation above.

NVENC runs on a discrete silicon IP core (SIP) block in the GPU, and not on
the GPU's shaders.
That SIP block has hard-coded limits (set in firmware) to ensure that these
who need more than the artificial limit buy Tesla-grade hardware.
Marketing shills by NVIDIA.
You can override this limit by u
I'm a little confused here because the GPU resource utilization is well
below the hard limits.
When I run nvidia-smi, this is what I get -

Hello,
I'm trying to figure out if I can use the QuickSync support to handle WMV
files. QuickSync itself I believe can handle WMV, but I don't see a codec
option I can invoke that appears to designate WMV decode using the qsv engine.
If I can't use qsv directly to handle wmv3, is it possible

You mentioned 30 streams. And more cause this to "fail".
Perhaps the Quadro line has a maximum simultaneous encoder limit of 30,
similar to the GeForce's limit of 2?

Hello everyone,
I'm currently using an NVIDIA Quadro P4000 GPU to transcode multicast UDP
streams to RTMP streams. I have quite about 30 streams running in parallel
on this GPU and I have no problems so far. I tried adding more today and
many of them are failing with this error.

Hello everybody
I have problems capturing a sdi flow with ffmpeg, I'm using a blackmagic
mini recorder pro, after a while of working the capture the audio is
distorted and the only way to fix it is to restart ffmpeg.
this is my pipeline
/usr/local/bin/ffmpeg -re -loglevel 48 -format_code pal -f d
I'm using ffmpeg to stream a live broadcast to another machine running
ffserver but the process won't run and I keep betting the error:
"Option rc_eq not found
Conversion failed!"
This is the ffmpeg command:
# .../ffmpeg-git-20171101-64bit-static/ffmpeg -y -f mpegts -i
/dev/dvb/adapter0/dvr0 -code

We are trying to match the output colour to the source content but although the
output formats matches the source we cannot get it to match.
Screenshot attached of the 3 outputs plus the original (top right) we have
tested with media info for each:
