What it does
Gstreamer is an agent skill from streamband/hydra-srt. Use this skill for GStreamer pipeline development and debugging: graph design, caps negotiation issues, latency, synchronization, and runtime diagnostics.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: An Open Source Alternative to Haivision SRT Gateway. The licence is Apache-2.0.
When your agent uses it
- GStreamer pipeline development and debugging: graph design
- Caps negotiation issues
- Synchronization
- Runtime diagnostics
Example prompts
- “/gstreamer”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Define expected media contract first: codec, resolution, framerate, latency budget.
- Build minimal pipeline that works end-to-end.
- Add elements incrementally and validate after each addition.
- Capture logs and DOT graphs when behavior diverges.
- Lock in working caps and buffering strategy.
What it can do on your machine
Read from SKILL.md and the folder at commit 8d081f2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gstreamer loads about 499 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 213 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Use this skill for GStreamer pipeline development and debugging: graph design, caps negotiation issues, latency, synchronization, and runtime diagnostics.
GStreamer Skill
When to use
Use for tasks with gst-launch, pipeline graphs, plugin selection, caps negotiation, timing/sync, encoder/decoder tuning, or stream reliability.
Workflow
- Define expected media contract first: codec, resolution, framerate, latency budget.
- Build minimal pipeline that works end-to-end.
- Add elements incrementally and validate after each addition.
- Capture logs and DOT graphs when behavior diverges.
- Lock in working caps and buffering strategy.
Core commands
- Quick run:
gst-launch-1.0 ... - Inspect plugin:
gst-inspect-1.0 <element> - Verbose logs:
GST_DEBUG=2 gst-launch-1.0 ... - Focused logs:
GST_DEBUG=GST_CAPS:6,GST_PADS:6,GST_EVENT:5 gst-launch-1.0 ... - Dump graphs:
GST_DEBUG_DUMP_DOT_DIR=/tmp GST_DEBUG=3 gst-launch-1.0 ...then render with Graphviz (dot -Tpng file.dot -o graph.png).
Debug heuristics
- If no data flow: verify pad link compatibility and capsfilter placement.
- If negotiation fails: inspect upstream/downstream caps and force explicit caps near boundaries.
- If latency spikes: inspect queue sizes, leaky settings, and encoder tune/preset.
- If A/V drift: inspect timestamps, clock selection, and sync flags.
- If intermittent drops: check jitter buffer, network burst tolerance, and keyframe interval.
Reliability patterns
- Use queues between thread domains.
- Set explicit caps at critical boundaries.
- Prefer explicit parser/payloader/depayloader elements rather than implicit auto-plugging in production.
- Add watchdog/health probes for long-running pipelines.
Validation checklist
- Startup time and steady-state latency measured.
- Recovery behavior tested (source restart / network jitter).
- CPU and memory stable under expected load.
- Logs include enough signal for postmortem.
