GStreamer 1.0 error : Failed to write input into the OpenMAX buffer

Hi,

I try this line command to read a yuv file, to encode it with the hardware encoder available in Jetson TX2 and then to save the result in a file :

gst-launch-1.0 filesrc location=/media/ubuntu/6634-3132/Basketball_640x360.yuv ! 'video/x-raw, width=(int)640, height=(int)360, format=(string)I420, framerate=(fraction)25/1' ! omxh264enc ! h264parse ! filesink location=/media/ubuntu/6634-3132/result1059s.h264 -e

But I obtain these errors :

Setting pipeline to PAUSED ...

Someone can help me to resolve the issues.

Thanks in advance.

Please try 640x368

Hi,

Thank you for your response, I change the height to 360, but I have always the same error. Could be an error related to the free space I have in my TX2, I have less than 2GB ?

Please put ‘videoparse’ and try again.

Hi Danell,

Thanks for your response. The problem is resolved by specifying the blocksize property for the filesrc element:

gst-launch-1.0 filesrc blocksize=345600 location=Basketball.yuv ! 'video/x-raw, width=(int)640, height=(int)360, format=(string)I420, framerate=(fraction)25/1' ! omxh264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! filesink location=results_block_size_345600.h264
