gstreamer log for filesrc

Hello,

We are trying to use the nvenc plugin of 1.7.2. But it failed when the source was from a file with an internal data flow error. We were using the example YUV video from NVIDIA Video Encoder SDK.

gst-launch-1.0 filesrc location=/sources/nvenc_sdk/Samples/YUV/1080p/HeavyHandIdiot.3sec.yuv ! videoconvert ! nvh264enc ! fakesink

Setting pipeline to PAUSED ...
ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0:
streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

The nvenc works with videotestsrc.

gst-launch-1.0 vidieotestsrc num-buffers=4000 ! videoconvert ! nvh264enc ! fakesink

Comment 2 Tim-Philipp Müller 2016-02-29 09:01:25 UTC 
This is expected behaviour in this case.

Try adding a videoparse element after filesrc (and make sure to configure it properly via properties).

Thanks for the instruction. Try with videoparse and it works.
