#146 fixed Strengthen calls to avcodec_decode_video2 Antoine Martin ahuillet
Description

Hello,

 * @warning The input buffer must be FF_INPUT_BUFFER_PADDING_SIZE larger than
 * the actual read bytes because some optimized bitstream readers read 32 or 64
 * bits at once and could read over the end.

We don't currently do that, and this could theoretically yield segfaults.

While we're at it, the input buffer should be aligned on a 32bit boundary, and it should end with a 0.

#147 fixed GL acceleration for client rendering Antoine Martin Antoine Martin
Description

(remaining) tasks:

  • provide a GL client window alternative to the standard gtk window, so OpenGL can take care of colourspace conversion, done in r922
  • urgent: fix vpx (ahuillet)
  • support all encodings (ie: mmap, jpeg and png)
  • do_expose_event isn't called automatically - fix it
  • fallback to non-GL rendering when PyOpenGL is not installed, or when the GL driver is blacklisted (or not whitelisted)
  • win32 build: we need to document how to build everything from scratch

Changes required from commit r922:

  • whitespace cleanup
  • remove wildcard imports
  • remove unused variables
  • constify GL command string
  • do not use SystemExit
  • why does this crash python??:
    python -c "from OpenGL.GL import glGetString, GL_VERSION; glGetString(GL_VERSION)"
    
  • remove duplicated window backing code: separate GL (backing) from window code - and re-use backing (super)class if needed. GLWindowBacking is not used??
  • use booleans and not integers (ie: vtxarrays - not used?)
  • use_openGL_CSC is hardcoded, make it a switch? Needs testing too.
  • self.current_mode and self.textures, need documenting more clearly, and initializing in constructor?
  • restore nogil for decompress_image_to_rgb: csc_image_yuv2rgb does not need the gil
  • run automated tests to compare with more scenarios

Contingency plan: we can disable the opengl code if this proves unstable or problematic.

Note:

  • with local connections, it might even be possible for the server to render directly to the client window? (even faster than mmap)
#148 fixed Xpra server deadlocks ahuillet ahuillet
Description

Hello,

I'm running Xpra server on debian stable (SVN version built from source, not the .deb). After some time (details still unclear to me), I can no longer attach to the server: the client will connect but nothing happens.

It seems to me that the server is actually deadlocked. Here is a backtrace for each of the threads running, starting with the thread that is worrying me:
