The global semaphore was never closed/unlinked, causing permission denied issue if the device is later used by another user. Properly removing the semaphore when stopping the pipeline would still leave it open in case of a crash. With a GStreamer specific name, it was also not preventing other apps to access the device concurrently. Finally, if the system has multiple cards, the lock should be per card and not global (to be confirmed). Fixes: #3283. Sponsored-by: Netflix Inc.

|
|
* Source element for [AJA](https://www.aja.com) capture cards.
|
|
*
|
|
* ## Example usage
|
|
*
|
|
* Capture 1080p30 audio/video and display it locally
|
|
*
|
|
* ```sh
|
|
* gst-launch-1.0 ajasrc video-format=1080p-3000 ! ajasrcdemux name=d \
|
|
* d.video ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! videoconvert ! autovideosink \
|
|
* d.audio ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! audioconvert ! audioresample ! autoaudiosink
|
|
* ```
|
|
*
|
|
* Capture 1080p30 audio/video and directly output it again on the same card
|
|
*
|
|
* ```sh
|
|
* gst-launch-1.0 ajasrc video-format=1080p-3000 channel=1 input-source=sdi-1 audio-system=2 ! ajasrcdemux name=d \
|
|
* d.video ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! c.video \
|
|
* d.audio ! queue max-size-bytes=0 max-size-buffers=0 max-size-time=1000000000 ! c.audio \
|
|
* ajasinkcombiner name=c ! ajasink channel=0 reference-source=input-1
