linux camera failed in long time recording

kevin_chan — Thu, 24 Jul 2014 06:01:16 GMT

platform: imx6q sabresd evk board

software: L3.0.35_4.1.0

i use gst to record from mipi camera (0v5640):

gst-launch mfw_v4lsrc fps-n=30 capture-mode=0 device=/dev/video1 ! queue ! vpuenc codec=6 ! matroskamux ! filesink location=mipi.mkv sync=false &

gst start record, but after some time, about 15 minutes, gst aborted with these error log: /****************************************************************************************************

ERROR: from element /GstPipeline:pipeline0/MFWGstV4LSrc:mfwgstv4lsrc0: Internal data flow error.

Additional debug info:

/****************************************************************************************************

i try to see the size of ouput:

du -sh mipi.mkv ---------- 40.0M mipi.mkv

And yocto-3.10.17_1.0.0 bsp has this problem too.

And a step further, i test this command:

gst-launch mfw_v4lsrc fps-n=30 capture-mode=0 device=/dev/video1 ! queue ! vpuenc codec=6 ! matroskamux ! fakesink sync=false &

it's ok even after 30 minutes.

can someone give me suggestion about this gst problem?

we need to do a long time camera recording. thanks

Please try using queue-size option of mfw_v4lsrc element.

$ gst-launch mfw_v4lsrc fps-n=30 capture-mode=0 device=/dev/video1 queue-size= 10 ! queue ! vpuenc codec=6 ! matroskamux ! filesink location=mipi.mkv sync=false

Have a great day,
Yuri
