This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3. This is based on top of an original patch by wm4 <nfxjfg@googlemail.com>. The original patch supported both encoding and decoding, but this patch only includes encoding. The patch contains further changes by Paweł Wegner <pawel.wegner95@gmail.com> (primarily for splitting out the encoding parts of the original patch) and further cleanup, build compatibility fixes and tweaks for use with Qualcomm encoders by Martin Storsjö. Signed-off-by: Martin Storsjö <martin@martin.st>
