[FFmpeg-devel] [PATCH] avformat/avio_internal: add av_warn_unused_result to ffio_ensure_seekback

[Ganesh Ajjanagadde]

This will trigger a few warnings that need to be fixed, as this function
can return AVERROR(ENOMEM).

--------------------------------------------------------------
Inspired by a patch sent by Paul for the IVR demuxer.
