[FFmpeg-devel] [PATCH 1/3] avcodec/v4l2_context: return EAGAIN to signal full buffers

[Andriy Gelman]

From: Andriy Gelman <andriy.gelman at gmail.com>

Return proper error when a frame buffers are full. This path is
triggered on the DragonBoard 410c since the encoding API change in
commit 827d6fe73d2f5472c1c2.
