Minor note: OpenGL by default assumes lines to be aligned to 4 bytes, and setting the row stride alone does not change that, so I think you'd get some strange output for that case.
Also the non-powerof-two support requirement means it won't run on many, many older GPUs, while in reality in my testing not being any faster (note: for most drivers glSubTexImage2D is preferable, repeated glTexImage2D can lead to memory fragmentation, it's like using av_free/av_malloc repeatedly instead of av_fast_malloc).
