# gst-validate
|
|
|
|
`gst-validate` is the simplest `gst-launch`-like pipeline launcher
|
|
running inside GstValidate monitoring infrastructure. Monitors are added
|
|
to it to identify issues in the used elements. At the end it will print
|
|
a report with some information about all the issues encountered during
|
|
its run. To view issues as they are detected, set the environment
|
|
variable `GST_DEBUG=validate:2`{.shell} and they will get printed in the
|
|
GStreamer debug log. You can basically run any [GstPipeline](GstPipeline) pipeline
|
|
using this tool. If you are not familiar with `gst-launch` syntax,
|
|
please refer to `gst-launch`'s documentation.
|
|
|
|
Simple playback pipeline:
|
|
|
|
gst-validate-1.0 playbin uri=file:///path/to/some/media/file
|
|
|
|
Transcoding pipeline:
|
|
|
|
gst-validate-1.0 filesrc location=/media/file/location ! qtdemux name=d ! queue \
|
|
! x264enc ! h264parse ! mpegtsmux name=m ! progressreport \
|
|
! filesink location=/root/test.ts d. ! queue ! faac ! m.
|
|
|
|
It will list each issue that has been encountered during the execution
|
|
of the specified pipeline in a human readable report like:
|
|
|
|
issue : buffer is out of the segment range Detected on theoradec0.srcpad at 0:00:00.096556426
|
|
|
|
Details : buffer is out of segment and shouldn't be pushed. Timestamp: 0:00:25.000 - duration: 0:00:00.040 Range: 0:00:00.000 - 0:00:04.520
|
|
Description : buffer being pushed is out of the current segment's start-stop range. Meaning it is going to be discarded downstream without any use
|
|
|
|
The return code of the process will be 18 in case a `CRITICAL` issue has
|
|
been found.
|
|
|
|
# Invocation
|
|
|
|
`gst-validate` takes a mandatory description of the pipeline to launch,
|
|
similar to `gst-launch`, and some extra options.
|
|
|
|
## Options
|
|
|
|
* `--set-scenario`: Let you set a scenario, it can be a full path to a scenario file or
|
|
the name of the scenario (name of the file without the `.scenario`
|
|
extension).
|
|
* `-l`, `--list-scenarios`: List the available scenarios that can be run.
|
|
* `--scenarios-defs-output-file`: The output file to store scenarios details. Implies
|
|
`--list-scenario`.
|
|
* `-t`, `--inspect-action-type`: Inspect the available action types with which to write scenarios if
|
|
no parameter passed, it will list all available action types
|
|
otherwize will print the full description of the wanted types.
|
|
* `--set-media-info`: Set a media\_info XML file descriptor to share information about the
|
|
media file that will be reproduced.
|
|
* `--set-configs`: Let you set a config scenario. The scenario needs to be set as
|
|
`config`. You can specify a list of scenarios separated by "`:`". It
|
|
will override the GST\_VALIDATE\_SCENARIO environment variable.
