[vlc-devel] [RFC PATCH 00/13] OMX: android hardware buffers: Take 2

[Thomas Guillem]

Hi,

Here is my second attempt to enable android hardware buffers on OMX (see my
first mail for more details).

I followed Martin advices (thank you again):

 - Reword some commit messages.

 - Add a copyright to the new files.

 - Fix some typos.

 - Don't remove/overwrite previous b_direct code and don't break anything.
   (omxil is still working with b_direct = false, b_direct = true, b_direct =
   true with hwbuf on).

 - Fix FreeBuffers: it was more complicated than I thought. Indeed, when using
   hwbuffers, buffers are not necessarily on OmxPort FIFO or on OMX side. They
   can also be hold by native_window (see min_undequeued) or on OmxHwBuffer
   FIFO. It was complicated to keep count of all FIFO, so I did a commit to
   change the way we wait for OMX Buffers to be returned (see RFC PATCH 12).

 - I also fixed a possible memory corruption (see RFC PATH 09).

I'll push the patches needed by vlc-android on the other mailing list.

Any comments are welcome.

Best Regards,
Thomas Guillem.
