Hello,
I’m working on Apalis IMX6 using Yocto.
I would like to play a TS file using Gstreamer and choose the played program.
At this time, i use the following command :
gst-launch-1.0 filesrc location=/mnt/usb/HD5_6Mbps_5min_v2.trp ! decodebin name = dec dec. ! queue ! audioconvert ! volume volume=10 ! alsasink dec. ! queue ! videoconvert ! imxg2dvideosink
This works fine but it’s always the first program of the TS file which is played.
Thanks in advance for your help.
Use a concrete pipe-line rather than using decodebin trying to detect demuxer.
NXP’s i.MX Linux User’s Guide may have some more usage information for multimedia use cases.
Their community may also have more specific answers in the multimedia domain.
You demuxer of choice may have a property to specify resp. program e.g. have a look at the output of the following command:
gst-inspect-1.0 aiurdemux
Hello,
Advantage of using decodebin is that video+audio codec is chosen automatically.
In the same TS, i can have MPEG2 video + MPEG4 Video.
It’s very hard to detect the stream, and build the pipe with good video codec + good audio codec !
Sure, I’m fully aware of decodebin’s advantages however if you want something rather special like being able to choose a particular program from an MPEG transport stream then I guess decodebin might not be able to serve you.
You can't have your cake and eat it too!
You might want to consider playbin rather than decodebin.
It has a property called current-audio and current-video that can be used to select a stream other than the default one.
of course but on my hardware, decodebin works better than playbin.
