Ah yeah, that's something else. This appears like it would happen as a result of ret = nouveau_bo_map(bsp_bo, NOUVEAU_BO_WR, dec->client); failing. No clue how that could happen... OTOH, I see messages about threads, and certainly video decoding + GL in different threads is highly likely to be broken with nouveau. Please try to build a debug version, see if that yields more info. Also look for errors in dmesg.
