What is GPU Transcoding with NVIDIA NVENC?
Protocol Definition & Architecture: Reseller Configuration
Technical Definition
NVENC is the hardware video encoder on NVIDIA GPUs used by panels to transcode ingest feeds into HEVC/H.264 bitrate ladders in real time. A single data-centre GPU encodes 20-40 1080p60 streams with sub-100 ms encode latency.
How It Operates Under the Hood
FFmpeg or the panel transcoder decodes the source with NVDEC, scales on the GPU, and encodes each rung with the hevc_nvenc preset p4-p6 at CBR with a VBV buffer equal to 2x bitrate. Audio is encoded on CPU (E-AC-3 or AAC).
Reseller Panel Configuration
Resellers should verify GPU Transcoding with NVIDIA NVENC on every new line with a 24-hour trial before invoicing. Document the expected values in your onboarding message so customers can self-serve, and escalate to the provider desk with a Wireshark capture when behaviour deviates.

GPU Transcoding with NVIDIA NVENC FAQ
What is GPU Transcoding with NVIDIA NVENC in simple terms?
NVENC is the hardware video encoder on NVIDIA GPUs used by panels to transcode ingest feeds into HEVC/H.264 bitrate ladders in real time. A single data-centre GPU encodes 20-40 1080p60 streams with sub-100 ms encode latency.
Why do some channels show encoder artifacts?
Overloaded transcoders drop presets to p1-p2, increasing blocking; providers scale GPUs during peak windows.
How are reseller credits priced and how is the margin calculated?
Credits are bought in tiers: $3.00 each at 50 credits, $2.20 at 100, $1.80 at 250, and $1.40 at 500+. One credit creates a 1-month line that retails for $10-$15. At the Pro tier (100 credits for $220) sold at $12/month, gross revenue is $1,200 and net profit is $980, a 445% return on the credit purchase.
How does multi-screen concurrency work and what happens if I exceed max_connections?
The Xtream Codes player_api.php handshake returns max_connections and active_cons. Each live or VOD stream request opens one session counted against that limit; a second TV, phone, or multi-view tile is a second connection. When active_cons would exceed max_connections, the server answers the new stream request with HTTP 403 / 458 and the player shows "max connections reached". Resellers should sell lines with 2-5 connections for households and enable IP-lock only for single-device subscribers.
What is device MAC address binding and why does my MAG box or Smart TV app ask for it?
Stalker / Ministra middleware authenticates a set-top box by its 48-bit MAC address (MAG boxes use the 00:1A:79 OUI prefix) instead of a username and password. The reseller panel binds that MAC to a subscription line; apps such as IBO Player and Smarters on Samsung or LG TVs generate a virtual MAC that must be registered the same way. If you replace the device, the panel must re-bind the new MAC or the portal returns an "unregistered device" error.
Do providers offer a free trial and how long does activation take?
Every network in this directory issues 24-hour trial lines from the reseller panel. Activation is instant: the panel writes the line to the Xtream database and the player can authenticate within 10 seconds. Trial lines are usually limited to 1 connection and exclude PPV bouquets.
What is the difference between Xtream Codes API, M3U URL, and Stalker Portal login?
All three deliver the same channels. Xtream Codes API uses player_api.php JSON endpoints so the player lazy-loads categories and EPG in seconds. An M3U URL (get.php) downloads a single text playlist of every stream, which is slow with 45,000 channels but works on any player. Stalker Portal authenticates by MAC address through a /c/ portal URL and is used by MAG receivers and some Smart TV apps.
