Expand description

Why an export of codec has no encoder, and what to do about it.

“h264 encoder is unavailable” reads like a bug in alpha2. What decides is the GPU-resident path, which says why it declined (gpu_output_unavailable, when the caller knows), the linked runtime, which says what it offers instead (offered, every codec’s encoders), and for H.264 whether OpenH264 is installed. The message names all three and the ways out.
