assertions from imxv4l2videosrc and h264 decode/encode #304

Closed hrc-amilcar closed 2 years ago

hrc-amilcar commented 2 years ago

Hello,

I have a pipeline that is reporting some assertions when connecting to the videorate plugin, imxvpudec_h264, and/or imxvpuenc_h264. I'm on a VAR-SOM-SOLO IMX6 and 2655bea for gstreamer-imx.

The video plays ok, but I wonder if there are any underlying issues or potential for crashes or leaks.

  1. videorate: The assert may be coming from a call to gst_buffer_pool_has_option on line 554 of gstimxv4l2videosrc.c. But perhaps the assert stems somewhere else in relation to videorate. Though I don't see a call to it in gstvideorate.c.
  2. h264: Not sure what is causing this one. Perhaps GstImxVpuEncH264. See object unref assert below.

I added a fix for the first assertion (the one from imxv4l2videosrc). The cause was that gst_query_parse_nth_allocation_pool() returns a NULL buffer_pool. Fixed in 4a489e6da3cb88a3908bf0008e4443aa1bc41f2d . The second assertion is still WIP.

Fixed second assertion. It had a similar cause (allocator can be NULL in the allocation params). Closing this now. Feel free to reopen if this still happens to you.
